Very helpful and to the point. The explanation isn't too fast. No matter the speed you'll have to replay if you want to really get something. Love the splitting hares!
+Milan chhatralia well, I usually go by x0.5 - it's not so much about what you're measuring, just to know which multiplier you are using especially when it comes to interpreting feedcharts or using calibration fluids stated in PPMs.
I've been watching your videos for a while now and I have to say that I like your style of presentation. I've watched videos where the presenter took so long to get to the point I moved on to another video. I did a lot of research and decided I would get an EC meter over a TDS meter simply because it just makes more sense, besides I can always pick one of the multipliers and do the math myself if I want PPM. P.S. I subscribed on the first video I stumbled upon.

+tv76g Hi tv76g-t's more about your growing media than your plant. When your growing media (presuming it is inert) is completely flushed it will read the same TDS as the water you use to flush it. This is easier with some media (e.g. rockwool) than others (coco) - look for a low CEC (cation exchange capacity). I'm going to make a video dedicated to flushing (been promising it for a while now!) so look out for that soon.
***** EC meters measures electrical conductivity and express it in milisiemens. TDS meters measures electrical conductivity, but they have built in software that converts the milisiemens into ppm(parts per million). The "problem with TDS meters is that they don't all multiply with the same values and therefore different TDS meters will give different readings, while all EC meters will give the same readings.. In example: If an EC meter gave a reading of 3, and the software on one TDS meter would multiply by 4 to to give you the reading in ppm, it would read 12 ppm, but the software on another TDS meter multiplies by 5 and will therefore read 15 ppm. In conclusion a TDS meter is an EC meter with software, that makes people confused and misunderstand eachother.
Hi Jonathan. Thanks for your question. I'm not aware of any method using just a regular EC meter because it measures overall conductivity created by all the solutes. I am aware of meters that allow you to measure specific ions (e.g. CleanGrow dot com) so they may be worth checking out.
Everest, Love your videos man and have ask a few questions since finding them. But I have another for you! In DWC, I am using a small 5 gallon tote that holds to my lever 3 gallons of water. I am currently trying to find my plants feeding EC by slowly raising the base of my EC to see where it will plateau (in-taking water, nutrients and dropping) all at the same rate (General Hydroponics Flora Series). Now for the question.. How much is TOO much of a concentrated solution to pre-mix to add to my reservoir, which I might add there is no roots exposed as top / netpot are pulled out and set in an empty tote while I have a small recirc pump that I drop into the bucket for mixing. My idea or what I have been doing the past few days is mix up 1/2 cup RO water, add my Micro at 2 parts, stir very well. Grow at 3 parts / stir and then my 1 part bloom. I have doubled this for a larger mixture when needed. Do you think I would run into a nute lockout issue with this method? I am trying to raise my EC in small increments and actually using PPM @ .5 (so increments of say 25-50).
I'm still confused because I found a thing online that called for so and so ec and so and so ppm I have been using grow more sea grow for my soil plants but want to grow herbs and spices in hydro as well as stray berries and maybe a cherry bush sooo do I add any npk ratio nutes until I get to ppm I want once I hit that ppm what if my ec isn't right? How's that adjusted From what I gather npk ratios go out the winder and all you want is ec or ppm reading right?
SPCkeith Hey SPCkeith. Thanks for your question. Start with a premium hydroponic nutrient (single part, grow A & B, bloom A &B, or three-part) and follow directions for vegetative, transition, and bloom that you'll see on the label. That way you don't have to concern yourself with the NPK as the nutrient blenders have largely done that work for you. Your responsibility, as you correctly determine, is the CONCENTRATION and pH of the nutrient solution you mix up. The more nutrient product you add, the higher the PPMs (Total dissolved solids (TDS)) or milisiemens (Electrical Conductivity (EC)). It's a bit like making a tropical fruit cordial drink. You can add a little for a light drink or a lot, for a sweet syrupy drink! Still the same tropical fruit cordial with the same blend of pineapple, peach and orange-just at different concentrations! :)
Everest Fernandez awesome thank you One more question if I may I know ph is number one but some of the charts I found listed differing ec for every plants but some plants had the same ppm needs but differant ec needs is ec just a bit more standard formulation? And ppm is really not as critical? If I'm following right? I'm looking to do one of them vertical hydro set up this year (like the rain tower or I think that's what it was) I'm wanting to do lettuce over the winter and then once the shipping opens for strawberries currently I have sea grow 16-16-16 and the 4-26-26 these are water soluble and from what I understand are ok for hydro use. I like to go as organic as I can but simple too With soil I use root riot cubes to start and then plant in black gold moving to dr earths pot of gold soil when the plants are slightly older and then I just water in half tsp per gallon of filtered water of the sea grow Can hydro be that simple and do you know any good products you can recommend? Thanks
SPCkeith Hey SPCKeith-PPMs, EC-these are two leaves on the same tree my friend. EC is a measure of electrical conductivity-typically measured in microsiemens per cm, sometimes written as µS/cm. TDS is a measure of the total dissolved solids, typically expressed as PPMs. To measure EC we use an EC meter-this passes a small amount of electricity between to electrodes and measures how much gets through. This is interesting to hydroponic growers because the more concentrated the nutrient solution, the better it conducts electricity. Now, to accurately measure PPMs you would need to evaporate all the water in your nutrient solution and weigh the solid residue. This, obviously is not practical for most folks-so we use a TDS meter. What is a TDS meter? It's an EC meter! Yes-the two are essentially the same thing! All your TDS meter is doing is measuring the EC (in microsiemens/cm) and using this to guess the PPMs. It does this using a conversion factor. Different minerals in solution confer different levels of conductivity so it can only guess. Normally I go by x 0.5-that is, 1000 microsiemens is equal to 500 PPMs. Hydroponics is simple. Begin with the purest water you can, invest in some good quality liquid hydroponic nutrients and monitor your growing environment (min max temperatures and relative humidity) and you're off to a great start!
Everest Fernandez gotcha between that and some other stuff I was reading makes sense now. Why do these things have to be so confusing haha soil growing has been my thing all my life but it'd time to learn new stuff Now when it come to nutes I'm looking at the maxi line from gh figure 3 parts how hard can it be or 2 parts minus the cool bloom are there any other good nutes like this? I currently use sea grow for my soil plants the 16-16-16 and the 4-26-26 any idea if those will work in hydro?
SPCkeith I recommend choosing a nutrient product that's designed specifically for hydroponic applications so that it has the right balance of nutrients (especially calcium and magnesium). The three part flora series by General Hydroponics is a mainstay of my hydroponic garden-works great, easy to use, versatile, pH stable. Go for it!
I use bluelab truncheon , | understand that in blulab truncheon we have ec .2 to.3.6 ms and NACL conversion factor tds 500 ppm,which is= ms x1000 x .5 and natural water conversion factor 700 ppm which is = ms x 1000x .7. when i read in fertilizer 4 18 38 , conductivity 1500 ppm , is that nacl or natural water conversion factor? thanks
+Dan Fox Yup I have one and they come pre-calibrated. I played with it last night checking the PPM on my tap water vs purified water. Tap water was 260-270 and purified was 0 PPM. Pretty cool stuff.
So my EC meter shows me uS (micro-siemens) When i look at a guide it will say that a certain crop needs EC 2.0. When i measure my tab water it is 1000uS or EC 1.0 Do i deduct the 1.0 and then add 2.0 worth of nutes giving me a total of 3.0 or do i only add 1.0 worth of nutes giving me a total of 2.0??? I hope im understanding everything. Im currently growing som chilis and my meter shows 1700uS which I figure is EC 1.7 and so far they looks strong and healthy.
Hey Michael. 2000 uS (or 2.0 mS) is your crop's limit. Don't go above it. You have very hard water. Invest in a water softener for your home (inexpensive) and a reverse osmosis water purifier for your grow. You're right 1.7 milisiemens (your EC meter's reading) is equivalent to 1700 microsiemens.
Everest Fernandez Thanks for your reply. I'm happy that i understand my readings correct. And i will stay below the EC limit. Yeah the water is VERY hard, but 100% chlorine free and super tasty. I will look into some RO and water softener (might be insanely expensive here though.)
Michael Hansen I am sure you can find a European-based supplier who can mail you a reverse osmosis filter for a reasonable price-but if you help then just send me a message as I know a few folks who'd be happy to help you.
Lisa Webster Hi Lisa. I have a video that shows me mixing up the nutrients, and another where I top up the reservoirs and change them out. But I definitely could do with making a video on nutrient solution maintenance and will hop right to it! :)
Awesome video. Is an EC test supposed to be able to tell you which nutrient is out of balance in your water? Or does it just tell you if your mixture needs topping up or diluting?
Hi Zeroizeable. An EC test is a good indicator of the total dissolved solids in your source water and you can usually make some reliable inferences about your water's hardness (typically calcium and magnesium carbonate and bicarbonate content) for example. As you mention, it can also indicate the concentration of your nutrient solution but it does not give you any data on specific mineral ions or nutrient balance. There are some more sophisticated meters on the market that do this, usually for commercial growers making up their own stock solutions.
+Everest Fernandez (Just4Growers) Thanks. Is it normal or common to use an EC test to check your nutrient solution levels, or is the test more about checking your source water's suitability?
+zeroizeable Both-but growers commonly used an EC meter to test their nutrient solution's conductivity, infer the concentration, and verify that it's suitable to feed to their plants.
Great video, I have a question, if I test a water sample with different PPM conversion tds, is the EC should be same but the PPM result vary?(If they can display both EC and PPM)
Well that was a really fast and complicated way to explain the metric system and converting units. But wheres the info on any of the content mentioned in the title?
Jordan Snyder hey Jordan, if you have any questions on TDS / PPM or EC (and conversion factors) that I didn’t cover in the video then please feel free to ask amigo. Peace.
As most people I can probably speak fast about subjects that are familiar to me, but if I am doing it with somone who is not it all sounds like Greek. luckily i have some experience so it was a little easier to follow but still rushed. However, a very informative video that I would love to explore and archive again at a slightly slower pace. Peace to you.
1997wolverine Thanks Wolverine. I received quite a bit of criticism on the pace of this video-it was, as you say, too fast for someone who is (likely) unfamiliar with the subject territory. I guess I had a LOT to say but I didn't want to go onnnnn and onnnn! :) It's definitely a topic that I intend to return to though, so I'll take a chill pill next time for sure! Thanks for stopping by. Happy growing, Everest.
I truly appreciate you saying that Wsochak! Thank you. I try to make vids that are beginner-friendly but still with enough content to interest more experienced growers. So much planned for the coming year! :)
dev bachu Yeah but you have to test the pH after the nutrients are in. If your PPM/EC is too high you'll have to add more nutrient free water and/or start over again if your pot/bucket is already to its limit with the amount of water it can hold...even if the pH is correct.
Some growers might be confused with EC reading and measured concentration being dependent on the ionic nature of each constituent. For example nacl is a good conductor where sugar solution doesn't conduct as well in equivalent molar concentrations. If you accurately measure your nutrients and carefully adjust your pH I believe measuring EC or PPM will serve as a guideline. Better still, a accurately prepare your "standard nutrient solution", measure that EC or PPM, as you prefer, then use that reading for future measurements. There is no real substitute for accuracy when using powerful nutrients with your grow.
Thanks for all your great videos! I'm a complete beginner when it comes to growing so my question might be very stupid: is there another video that explains what desirable ppm levels are for given vegtables?
Dear everest I can't understand when we mix nutritions together how we calculate Ms to PPM in mixed nutrition we have different types of conversion factors 🙈🙄🤔🤔😣 can you learn us the easy way
Great video dude , enjoyed as hell. Great speech speed and presentation :D. Literally was smiling the whole video.

This item you are viewing is a 3 in 1 Nutrient Tester to determine the nutrient levels in a solution with 3 parameters (CF, EC and PPM).（YM-2005A） If you use hydroponics to grow fruits and plants, it is necessary to know the strength of nutrients.
Accidentally had this vid going at 1.5x 🤪 ... But you are so we'll pronounced and articulated, that I was almost able to follow it all ... Almost. Also thank you for the enormous amount of concise information!
First video I've seen from this channel. Will be the last time I watch a video from this channel. Might as well watch reruns of a micro machine commercial.
I think your vids are awesome EF. Watching some of these other vids w ppl who are high and slow is very frustrating. I live in NYC, speed it up even further. It's a sin you only have 55 subs.
There's a lot of info to take in here, it really isn't helpful that the guy presenting it seems to have ingested a large quantity of amphetamine shortly prior to making the video. Unless your camera has a 256MB memory card, I really don't think it was necessary to rush through it at such speed. I watched the video wanting to understand this stuff, it left me thinking "What?"
Thanks DJ Messy. Lol. My camera has two 64GB memory cards (now I'm showing off) but I just can't stand long waffley videos so I tune them to suit my own attention deficit disorder-sorry. I really should make a (slower) follow-up to this video as you're not the first to convey such sentiments :) Thanks again for the feedback. Peace and happy growing, Everest.

Flipside is folks can slow you down if they want :) But yeah, I agree, fun to watch but a little slower would be better. But I still appreciate the video very much, thanks, I learned a lot (in a short time)
Fast but explained really well thanks because I'm puerto rican and when I whach spanish videos they talk about ec and when I see english videos they talk about ppm i understand now..
Im still confused. My location is SE Asia. Scratching the hair off my head trying to.sort out my nutrient water solution and soil runoff. My TDS-EC meter displays ppm and EC. so when it displays 0.600EC is that the same as 6000 microsiemens?
Hi Jay, thanks for your comment. When your TDS-EC meter displays 0.600 EC that's 0.6 milisiemens. 1 milisiemen = 1000 microsiemens, so 0.6 milisiemens = 600 microsiemens, not 6000. Typically, you would grow vegetative crops around 1.2 milisiemens or 1200 microsiemens. Some flowering crops require feeds up to 3.0 milisiemens or 3000 microsiemens, or higher. Stick with SI units like milisiemens / microsiemens.
getting a tds sensor because they're more availible than ec meters, i'll run the conversion factor through the arduino nano if i can find teh specifications of the tds meter, thank you for this
Sir you made my day... Thanx a lot I was searching for the same from long time but no one could ake me understand yet in such a simple language. Thanx a lot lot lot Lott..
Kenneth Elston Sorry Kenneth-you're certainly not the first to convey similar sentiments. I think I tried to pack in too much info into too short a time. The strength of a nutrient solution is physically based on the amount of minerals dissolved in it. However, I was trying to say that your TDS meter (what we use to measure nutrient solution strength) is really an electrical conductivity meter! It's just a bit of software inside that takes the nutrient solution's electrical conductivity and calculates (or rather estimates) your total dissolved solids (in PPMS or parts per million). Different TDS meters make the conversion between electrical conductivity (in milisiemens) to TDS (in PPMs) using different conversion factors-so it's important to know which conversion factor your meter (or calibration fluid) is using. You can forget all about this if you choose to stick with EC like the Europeans do-like the metric system, it makes far, far more sense! :) Still clear as mud? :)
Great video. However, can you tell me how PPMs and EC have relate to pH? My meter (from Mudder on eBay) is called a "pH or TDS meter". It measures in PPMs. So what's the pH of the solution?
Conductivity has no relation to pH Don. Check out my video pH for Hydroponics 101. Happy to answer any questions you may have. I can get into the whys and hows! :)
Mr. Everest!! I love the speed of your video! A lot of us do! I hope most, so you can keep it up!! On to my question...it may be silly, but I want to make sure. You suggest going with an EC meter correct? Seems like there's too much room for error with the USA way...foolishly may I add
An ORP [Oxidation-Reduction Potential] meter measures your water’s ability to either gain or lose electrons in chemical reactions. Oxidizing: Means the water can accept electrons, which often indicates the presence of disinfectants like chlorine or ozone, used to break down contaminants. Reducing: Means the water is capable of giving up electrons, suggesting it might contain reducing agents like hydrogen sulfide or organic matter. An ORP meter gives a single number in millivolts (mV), which reflects how oxidizing or reducing the water is, helping assess the water’s cleanliness and disinfection status. Interpreting ORP Readings: Positive ORP Value (e.g., +200 mV): Indicates that the solution has a greater oxidizing ability, meaning it can accept electrons from other substances. A higher positive value generally suggests a stronger oxidizing agent, which is good for killing bacteria or disinfecting water (e.g., chlorinated water). Positive values are common in environments with disinfectants or oxidizers like chlorine, ozone, or hydrogen peroxide. Negative ORP Value (e.g., -200 mV): Indicates that the solution has a greater reducing ability, meaning it can donate electrons to other substances. A lower negative value suggests the solution contains reducing agents like organic matter, sulphur compounds, or unoxidized metals. Negative ORP values are often found in environments with decaying organic matter or polluted water. General Interpretation Guidelines: +200 to +400 mV: Water is moderately oxidizing; good for drinking water treatment. Above +600 mV: Strong oxidizing conditions, suitable for disinfection (like swimming pools). 0 to -200 mV: Mildly reducing; often found in natural water bodies. Below -400 mV: Strong reducing conditions, which could indicate the presence of contaminants or decaying matter. For hydroponic systems, the ideal ORP range for a nutrient solution typically falls between +200 to +300 mV. This range ensures that the water is slightly oxidizing, promoting a balance between nutrient availability and microbial control. Here's why this range works well: +200 to +300 mV: In this range, the solution maintains a healthy level of disinfection without being overly oxidizing, which can harm beneficial microorganisms or plant roots. It also ensures that the nutrients remain available for plant uptake. If the ORP goes too high (e.g., above +400 mV), it may indicate excessive oxidizing agents (like chlorine), which could stress or damage plants. Conversely, if the ORP falls too low (below 0 mV), it could indicate a lack of oxygen or microbial activity, which can lead to poor plant growth or the development of pathogens. Hope this helps!
@@Just4Growers thank you will read this a couple of times till it goes in but that is by far the best explanation of a orb meter. Much appreciated. 🫶🏻 So if I got this right, if you have a low reading would you either change res or add more hydrogen peroxide if you were running sterile rdwc? I want to fit a growtek dosing system and it has an orb meter. It’s going to be connected to the buckets so it can dose while it’s recirculating and be topped up by RO in the res. So I’m assuming I could put a peroxide on one of the dose pumps
You all complaining about talking speed? Instead of trying to get the channel to change to suit you, why not just watch the video again?? I've seen several of the channels videos multiple times and then ask questions to gain a better understanding. And I still don't get all of it. This is one of the two best and most informative channels on TH-cam for growing and product variety and reviews. It was hard for me to keep up the first time I watched one of his vids, but if I had quit at the beginning I wouldn't have learned anything.

Perhaps my sleepy slow comment hit you on the chin. I bet it takes you fucking 5 minutes to read one page of a book with 5% comprehension.
0.5 is the conversion factor, not the actual reading. So using this scale, 2.0 mS (EC) = 2000 uS = 1000 PPM (2000 X 0.5). If you were using the 0.7 conversion factor then it would be 2000 X 0.7 = 1400 PPM. As you can see, the conversion factor you use can make quite a difference so .... just use EC like those friendly, sensible Europeans.
call me dumb but im even more confused man i should have stayed in school lol is there a online conversion tool? i have a feeling im about to buy a 100+$ tool that im going to just sit and look at all confused that will end up on the shelf
Just wanted to say that I love your videos Everest just the way they are! I understand some people may have a hard time processing all the information you throw at them, but that is exactly why others have pointed out the fact that the video speed can indeed be slowed down. So problem solved! Anyways, I truly appreciate your delivery because it helps me cram a bunch of stuff into a short study time, especially for quick refreshers when I have a brain fart.

OK, it did cover the subject, but in such a manner that the average person cannot make notes useful for later. It also did not provide links to printed material for later use. Their goal was only to show their knowledge, and I'll bet they didn't do it without notes.
Although humorous, ya might want to slow down just a tad. ;-) informative yet I am still lost. I just learned about "EC" & SIEMENS, MILLISIEMENS & microsiemens. I have a tds meter i need new batteries for. They are battery vampires apparently. However i dont recognize where it says what the conversion is in the barely 1 page paper that tells about it.
***** Thanks Kevin. A few viewers mirrored your comments so from now on I always strive for clarity before brevity. Happy to answer any questions you might have on the matter. Basically EC really is the way to go when measuring nutrient conductivity in the real world. PPMs .... meh!
***** Well Kevin having a PPM meter is a good start! I think of it like this: Water is a solute-in other words, it dissolves stuff. (I know, you knew that already! :-)) However, to really know what's dissolved in your water you need to see what's left when you boil it all away and perform lab tests for the presence of various minerals in the residue that's left over. You might find, for instance, that you have 75 PPMs of calcium in your water and 12 PPMs of magnesium in your water-but only a lab test could tell you that. Of course, as growers, we don't need to rely on laboratories! We use TDS meters: Total Dissolved Solids. This guesses the total of all the different dissolved elements in your water in PPMs. 75 + 12 + whatever else is in there.... However, TDS meters are only guessing! They don't actually count up the calcium PPMs and the Magnesium PPMs etc... they measure how well the water conducts electricity-i.e. they are conductivity meters in disguise! Lol! Pure water conducts very little electricity. However, as you dissolve elements in water, it can conduct more electricity. Thus, water's electrical conductance can be used to INFER the total dissolved solids in it. If our test water is conducting relatively large amounts of electricity we can safely assume that there are a lot of dissolved solids in it. If our test water conducts very little, we can assume it's pretty pure. Different elements (sodium, calcium, magnesium, etc) conduct electricity better than others. So that's why different conversion factors are used-they are always guesses-but it gives us a good indication. Growers in Europe skip this stage and simply use electrical conductance as a measure of how concentrated their nutrient solutions are. I'm with the Europeans on this one. They have one measurement to go by (in microsiemens or milisiemens) and don't have to worry about conversion factors. So my advice-go get yourself a Bluelab conductivity meter (ask for 'the truncheon' but make sure it says Bluelab-you can't go wrong with this brand) and think of your nutrient strength in terms of electrical conductance rather than those pesky PPMs! I'm happy to keep discussing this until it's clear my friend so don't hesitate to come back with any questions. Peace and happy growing, Everest.
We have been drinking RO water in our house for 30 years. I even tested for dissolved solids for my clients as a health professional. But we are trying to remove those solids from water, not add them lol.
Anyone know if you could measure the Chlorine levels or at least meter them using a TDS meter ? I bought one of the Chlorine test meters from ebay :/ www.ebay.ca/itm/pH-CL2-Chlorine-Level-Meter-TDS-Water-Quality-Tester-Monitor-frSwimming-pool-spa-/311347766798?pt=LH_DefaultDomain_0&hash=item487dc5e60e AND when I put some pink salt into the glass of water the chorine reading shot waaay up... Of course the TDS meter reading also went from 15 ppm to 221 ppm. The PH reading appeared good, I compared it to my Milwaukee PH meter and it was within 0.1 of the Milwaukee reading so I call that a passing grade. I`m stumped, ether the Chlorine meter is crap or all chlorine testing kits do the same if you add pink salt...???
NoFear4XJs Hey NoFear. Thanks for your question. A TDS meter does not measure chlorine levels. It will measure chlorides such as sodium chloride but that's a totally different thing. A TDS meter is just a conductivity meter with some onboard software to estimate / infer the total amount of dissolved salts. As such, your TDS meter will only change when you add solutes that impact the conductivity of the water, which most salts do. If that helped please consider subbing my channel! Thanks :)

So what should your TDS meter read when your plant is completely flushed? Hope you can help? Thanks
+tv76g Hi tv76g-t's more about your growing media than your plant. When your growing media (presuming it is inert) is completely flushed it will read the same TDS as the water you use to flush it. This is easier with some media (e.g. rockwool) than others (coco) - look for a low CEC (cation exchange capacity). I'm going to make a video dedicated to flushing (been promising it for a while now!) so look out for that soon.
Nice video. Question. What is the ideal ppm reading of my water before adding the nutrients?
Thanks Stallone. Zero is ideal. 0 ppms. Reverse osmosis is the way forward.
Everest Fernandez If you can't use a distiller....
hi Everest what doe you think about Torus Hydro ph control ?
So EC is the same as PPM or TDS ? Just different math ?
*****
EC meters measures electrical conductivity and express it in milisiemens.
TDS meters measures electrical conductivity, but they have built in software that converts the milisiemens into ppm(parts per million). The "problem with TDS meters is that they don't all multiply with the same values and therefore different TDS meters will give different readings, while all EC meters will give the same readings..
In example: If an EC meter gave a reading of 3, and the software on one TDS meter would multiply by 4 to to give you the reading in ppm, it would read 12 ppm, but the software on another TDS meter multiplies by 5 and will therefore read 15 ppm.
In conclusion a TDS meter is an EC meter with software, that makes people confused and misunderstand eachother.
William Hansen Thanks William. That's it in a nutshell! In Europe, growers go by EC and save themselves a whole lot of potential confusion!
would you happen to know if it is possible to calculate certain macro and micro nutrients such as potasium, nitrogen, iron with just an ec meter?
Hi Jonathan. Thanks for your question. I'm not aware of any method using just a regular EC meter because it measures overall conductivity created by all the solutes. I am aware of meters that allow you to measure specific ions (e.g. CleanGrow dot com) so they may be worth checking out.
One thing I was looking for that you didn't explain is how do I change the ppm. If I'm in Veg, the suggested is 8-900. How do I get to that number?
Richondo Fabiano By adding or subtracting nutrients...
Everest,
Love your videos man and have ask a few questions since finding them. But I have another for you!
In DWC, I am using a small 5 gallon tote that holds to my lever 3 gallons of water. I am currently trying to find my plants feeding EC by slowly raising the base of my EC to see where it will plateau (in-taking water, nutrients and dropping) all at the same rate (General Hydroponics Flora Series).
Now for the question.. How much is TOO much of a concentrated solution to pre-mix to add to my reservoir, which I might add there is no roots exposed as top / netpot are pulled out and set in an empty tote while I have a small recirc pump that I drop into the bucket for mixing.
My idea or what I have been doing the past few days is mix up 1/2 cup RO water, add my Micro at 2 parts, stir very well. Grow at 3 parts / stir and then my 1 part bloom. I have doubled this for a larger mixture when needed. Do you think I would run into a nute lockout issue with this method? I am trying to raise my EC in small increments and actually using PPM @ .5 (so increments of say 25-50).
I'm still confused because I found a thing online that called for so and so ec and so and so ppm I have been using grow more sea grow for my soil plants but want to grow herbs and spices in hydro as well as stray berries and maybe a cherry bush sooo do I add any npk ratio nutes until I get to ppm I want once I hit that ppm what if my ec isn't right? How's that adjusted
From what I gather npk ratios go out the winder and all you want is ec or ppm reading right?
SPCkeith Hey SPCkeith. Thanks for your question. Start with a premium hydroponic nutrient (single part, grow A & B, bloom A &B, or three-part) and follow directions for vegetative, transition, and bloom that you'll see on the label. That way you don't have to concern yourself with the NPK as the nutrient blenders have largely done that work for you. Your responsibility, as you correctly determine, is the CONCENTRATION and pH of the nutrient solution you mix up. The more nutrient product you add, the higher the PPMs (Total dissolved solids (TDS)) or milisiemens (Electrical Conductivity (EC)).
It's a bit like making a tropical fruit cordial drink. You can add a little for a light drink or a lot, for a sweet syrupy drink! Still the same tropical fruit cordial with the same blend of pineapple, peach and orange-just at different concentrations! :)
Everest Fernandez awesome thank you
One more question if I may I know ph is number one but some of the charts I found listed differing ec for every plants but some plants had the same ppm needs but differant ec needs is ec just a bit more standard formulation? And ppm is really not as critical? If I'm following right?
I'm looking to do one of them vertical hydro set up this year (like the rain tower or I think that's what it was)
I'm wanting to do lettuce over the winter and then once the shipping opens for strawberries currently I have sea grow 16-16-16 and the 4-26-26 these are water soluble and from what I understand are ok for hydro use. I like to go as organic as I can but simple too
With soil I use root riot cubes to start and then plant in black gold moving to dr earths pot of gold soil when the plants are slightly older and then I just water in half tsp per gallon of filtered water of the sea grow
Can hydro be that simple and do you know any good products you can recommend? Thanks
SPCkeith Hey SPCKeith-PPMs, EC-these are two leaves on the same tree my friend. EC is a measure of electrical conductivity-typically measured in microsiemens per cm, sometimes written as µS/cm. TDS is a measure of the total dissolved solids, typically expressed as PPMs.
To measure EC we use an EC meter-this passes a small amount of electricity between to electrodes and measures how much gets through. This is interesting to hydroponic growers because the more concentrated the nutrient solution, the better it conducts electricity.
Now, to accurately measure PPMs you would need to evaporate all the water in your nutrient solution and weigh the solid residue. This, obviously is not practical for most folks-so we use a TDS meter.
What is a TDS meter? It's an EC meter! Yes-the two are essentially the same thing!
All your TDS meter is doing is measuring the EC (in microsiemens/cm) and using this to guess the PPMs. It does this using a conversion factor. Different minerals in solution confer different levels of conductivity so it can only guess. Normally I go by x 0.5-that is, 1000 microsiemens is equal to 500 PPMs.
Hydroponics is simple. Begin with the purest water you can, invest in some good quality liquid hydroponic nutrients and monitor your growing environment (min max temperatures and relative humidity) and you're off to a great start!
Everest Fernandez gotcha between that and some other stuff I was reading makes sense now. Why do these things have to be so confusing haha soil growing has been my thing all my life but it'd time to learn new stuff
Now when it come to nutes I'm looking at the maxi line from gh figure 3 parts how hard can it be or 2 parts minus the cool bloom are there any other good nutes like this? I currently use sea grow for my soil plants the 16-16-16 and the 4-26-26 any idea if those will work in hydro?
SPCkeith I recommend choosing a nutrient product that's designed specifically for hydroponic applications so that it has the right balance of nutrients (especially calcium and magnesium). The three part flora series by General Hydroponics is a mainstay of my hydroponic garden-works great, easy to use, versatile, pH stable. Go for it!
I use bluelab truncheon , | understand that in blulab truncheon we have ec .2 to.3.6 ms and NACL conversion factor tds 500 ppm,which is= ms x1000 x .5 and natural water conversion factor 700 ppm which is = ms x 1000x .7.
when i read in fertilizer 4 18 38 , conductivity 1500 ppm , is that nacl or natural water conversion factor? thanks
Bluelab's truncheon (great piece of kit!) actually shows EC, x0.5 and x0.7 scales.
+Dan Fox Yup I have one and they come pre-calibrated. I played with it last night checking the PPM on my tap water vs purified water.
Tap water was 260-270 and purified was 0 PPM. Pretty cool stuff.
Say I want to give a feeding of 200ppm but my source water is already 150ppm... Should I mix my nutes then till I reach a ppm of 350?
how do u adjust it, correct it
I have an apera ec20 , what would be my conversion for ppm?
which one should I buy please
So my EC meter shows me uS (micro-siemens)
When i look at a guide it will say that a certain crop needs EC 2.0.
When i measure my tab water it is 1000uS or EC 1.0
Do i deduct the 1.0 and then add 2.0 worth of nutes giving me a total of 3.0 or do i only add 1.0 worth of nutes giving me a total of 2.0???
I hope im understanding everything. Im currently growing som chilis and my meter shows 1700uS which I figure is EC 1.7 and so far they looks strong and healthy.
Hey Michael. 2000 uS (or 2.0 mS) is your crop's limit. Don't go above it. You have very hard water. Invest in a water softener for your home (inexpensive) and a reverse osmosis water purifier for your grow. You're right 1.7 milisiemens (your EC meter's reading) is equivalent to 1700 microsiemens.
Everest Fernandez
Thanks for your reply.
I'm happy that i understand my readings correct. And i will stay below the EC limit.
Yeah the water is VERY hard, but 100% chlorine free and super tasty. I will look into some RO and water softener (might be insanely expensive here though.)
+Michael Hansen whereabouts in the world are you?
Copenhagen, Denmark
Michael Hansen I am sure you can find a European-based supplier who can mail you a reverse osmosis filter for a reasonable price-but if you help then just send me a message as I know a few folks who'd be happy to help you.
Do you have a video showing the actual process of how to check the nutrient solution?
Lisa Webster Hi Lisa. I have a video that shows me mixing up the nutrients, and another where I top up the reservoirs and change them out. But I definitely could do with making a video on nutrient solution maintenance and will hop right to it! :)
Awesome video. Is an EC test supposed to be able to tell you which nutrient is out of balance in your water? Or does it just tell you if your mixture needs topping up or diluting?
Hi Zeroizeable. An EC test is a good indicator of the total dissolved solids in your source water and you can usually make some reliable inferences about your water's hardness (typically calcium and magnesium carbonate and bicarbonate content) for example. As you mention, it can also indicate the concentration of your nutrient solution but it does not give you any data on specific mineral ions or nutrient balance. There are some more sophisticated meters on the market that do this, usually for commercial growers making up their own stock solutions.
+Everest Fernandez (Just4Growers) Thanks. Is it normal or common to use an EC test to check your nutrient solution levels, or is the test more about checking your source water's suitability?
+zeroizeable Both-but growers commonly used an EC meter to test their nutrient solution's conductivity, infer the concentration, and verify that it's suitable to feed to their plants.
Keep reading, you'll answer yer own ?
" "brand name here" meters are calibrated with a 342 ppm NaCl solution"
I'm guessing this means the meter will use the NaCl conversion?
+Middle Finger yes.
@JJ different conversion factor means you will have a different reading as stated in the video 3:20
@JJ the meters are all the same but the internal multiplying factor differs
Hi am in the uk and use a blue lab truncheon, and I like you said only do my EC readings by my canna nutrient chart, is this wrong? or am I fine
As a layman I found this informative. I appreciated the visuals as well. This was beneficial to me, thank you.
I found this useful. I have watched other videos prior to watching this.
I just bought an EC pen and it’s measuring “1486” EC. Assuming this is 1.4?
JORDAN DAVIES Yes amigo, your EC meter is displaying its reading in microsiemens: 1486 microsiemens = 1.486 milisiemens.
Great video, I have a question, if I test a water sample with different PPM conversion tds, is the EC should be same but the PPM result vary?(If they can display both EC and PPM)
Well that was a really fast and complicated way to explain the metric system and converting units. But wheres the info on any of the content mentioned in the title?
Jordan Snyder hey Jordan, if you have any questions on TDS / PPM or EC (and conversion factors) that I didn’t cover in the video then please feel free to ask amigo. Peace.
As most people I can probably speak fast about subjects that are familiar to me, but if I am doing it with somone who is not it all sounds like Greek. luckily i have some experience so it was a little easier to follow but still rushed. However, a very informative video that I would love to explore and archive again at a slightly slower pace. Peace to you.
1997wolverine Thanks Wolverine. I received quite a bit of criticism on the pace of this video-it was, as you say, too fast for someone who is (likely) unfamiliar with the subject territory. I guess I had a LOT to say but I didn't want to go onnnnn and onnnn! :) It's definitely a topic that I intend to return to though, so I'll take a chill pill next time for sure! Thanks for stopping by. Happy growing, Everest.
Are we in an auction?
CHAB HENG Sorry Chab-so much to say, so little time! :)
Finally someone explained EC for me to understand.
You’re welcome!
Great videos Everest. Been growing for many moons and still enjoying grow videos that are educational and professional. Thanks.
I truly appreciate you saying that Wsochak! Thank you. I try to make vids that are beginner-friendly but still with enough content to interest more experienced growers. So much planned for the coming year! :)
can I just test the pH an adjust the ph
dev bachu Yeah but you have to test the pH after the nutrients are in. If your PPM/EC is too high you'll have to add more nutrient free water and/or start over again if your pot/bucket is already to its limit with the amount of water it can hold...even if the pH is correct.
FAK MAN, NOW I AM MORE CONFUSED, THANK YOU!
😂😂
So confused. Why do ppl waste time don't this?
Boy i end up as smart as i was when i took my first computer lesson class , WTF ... i have to watch it all over again. Tks for sharing
Been looking 20 minutes for this information than remembered im subscribed to the genius 😁🙏
Some growers might be confused with EC reading and measured concentration being dependent on the ionic nature of each constituent. For example nacl is a good conductor where sugar solution doesn't conduct as well in equivalent molar concentrations. If you accurately measure your nutrients and carefully adjust your pH I believe measuring EC or PPM will serve as a guideline. Better still, a accurately prepare your "standard nutrient solution", measure that EC or PPM, as you prefer, then use that reading for future measurements. There is no real substitute for accuracy when using powerful nutrients with your grow.
Helllo, good afternoon!! Can I use this equipments to measure a home made fertiliser? I love your job! Class!
Thanks for all your great videos!
I'm a complete beginner when it comes to growing so my question might be very stupid: is there another video that explains what desirable ppm levels are for given vegtables?
That's some good Peruvian marching powder he's on
Black maca? 😅
Superb again. The pace of your vids is great, no time wasted. Thanks mate
If Tds says 1200، what is that in ppm ?
The tds device says it’s up to usa epa !
Just tell me what's the difference between TDS and PPM ????
So do I use ppm 500 or 700 setting with my general hydroponic nutrients? Thanks Everest....
+Jonathan Bermudez Hi Jonathan. Use the PPMx500 setting. goo.gl/ly1s71
Dear everest I can't understand when we mix nutritions together how we calculate Ms to PPM in mixed nutrition we have different types of conversion factors 🙈🙄🤔🤔😣 can you learn us the easy way
Highly concentrated information...good!

Mr Mister You just ruthlessly killed my buzz ... man.
This item you are viewing is a 3 in 1 Nutrient Tester to determine the nutrient levels in a solution with 3 parameters (CF, EC and PPM).（YM-2005A） If you use hydroponics to grow fruits and plants, it is necessary to know the strength of nutrients.
Accidentally had this vid going at 1.5x 🤪 ... But you are so we'll pronounced and articulated, that I was almost able to follow it all ... Almost.
Also thank you for the enormous amount of concise information!
First video I've seen from this channel. Will be the last time I watch a video from this channel. Might as well watch reruns of a micro machine commercial.

@@Just4Growers Don't worry if slow people can't keep up.
I loved this video so much, I watch it whenever I am dissolving my nutrients, I mean my plant nutrients.
There's a lot of info to take in here, it really isn't helpful that the guy presenting it seems to have ingested a large quantity of amphetamine shortly prior to making the video. Unless your camera has a 256MB memory card, I really don't think it was necessary to rush through it at such speed. I watched the video wanting to understand this stuff, it left me thinking "What?"
Thanks DJ Messy. Lol. My camera has two 64GB memory cards (now I'm showing off) but I just can't stand long waffley videos so I tune them to suit my own attention deficit disorder-sorry. I really should make a (slower) follow-up to this video as you're not the first to convey such sentiments :) Thanks again for the feedback. Peace and happy growing, Everest.
@@Just4Growers If you hadn't gone at that speed, you'd have been on my default 2x playback speed. Flipside is folks can slow you down if they want :) But yeah, I agree, fun to watch but a little slower would be better. But I still appreciate the video very much, thanks, I learned a lot (in a short time)
I sped it up so I appreciate the speed of data and his blood stream should that be the case.
Fast but explained really well thanks because I'm puerto rican and when I whach spanish videos they talk about ec and when I see english videos they talk about ppm i understand now..
Im still confused. My location is SE Asia. Scratching the hair off my head trying to.sort out my nutrient water solution and soil runoff. My TDS-EC meter displays ppm and EC. so when it displays 0.600EC is that the same as 6000 microsiemens?
Hi Jay, thanks for your comment. When your TDS-EC meter displays 0.600 EC that's 0.6 milisiemens. 1 milisiemen = 1000 microsiemens, so 0.6 milisiemens = 600 microsiemens, not 6000. Typically, you would grow vegetative crops around 1.2 milisiemens or 1200 microsiemens. Some flowering crops require feeds up to 3.0 milisiemens or 3000 microsiemens, or higher. Stick with SI units like milisiemens / microsiemens.
Finally it is explained. Btw - American here and I am going EC. Cheers!
Awesome. One grower converted to EC. Just 300 million more to go. :)
i grow corn , can't talk to plants .. just goes in one ear and out the other
Lol.
getting a tds sensor because they're more availible than ec meters, i'll run the conversion factor through the arduino nano if i can find teh specifications of the tds meter, thank you for this
Nutrient strength explained like never before!

Pushkaraj Chaudhari Thanks Pushkaraj I am glad that you found this helpful.
i finally understeand the difference, thank you so much!
That was clear as mud to me!!!
Kenneth Elston Sorry Kenneth-you're certainly not the first to convey similar sentiments. I think I tried to pack in too much info into too short a time. The strength of a nutrient solution is physically based on the amount of minerals dissolved in it. However, I was trying to say that your TDS meter (what we use to measure nutrient solution strength) is really an electrical conductivity meter! It's just a bit of software inside that takes the nutrient solution's electrical conductivity and calculates (or rather estimates) your total dissolved solids (in PPMS or parts per million). Different TDS meters make the conversion between electrical conductivity (in milisiemens) to TDS (in PPMs) using different conversion factors-so it's important to know which conversion factor your meter (or calibration fluid) is using. You can forget all about this if you choose to stick with EC like the Europeans do-like the metric system, it makes far, far more sense! :) Still clear as mud? :)
Great video. However, can you tell me how PPMs and EC have relate to pH? My meter (from Mudder on eBay) is called a "pH or TDS meter". It measures in PPMs. So what's the pH of the solution?
Conductivity has no relation to pH Don. Check out my video pH for Hydroponics 101. Happy to answer any questions you may have. I can get into the whys and hows! :)
Awesome man, cool explanation, now I got it
Mr. Everest!! I love the speed of your video! A lot of us do! I hope most, so you can keep it up!! On to my question...it may be silly, but I want to make sure. You suggest going with an EC meter correct? Seems like there's too much room for error with the USA way...foolishly may I add
EC (milisiemens) is the way to go amigo. Just like Celsius, Kilopascals and Kilometers. :)
I don't see the point of the ec meter the different shades of green tell me how much urine and ash I need to mix with water to feed my plants.
You have the best and most accurate information I've ever heard, and probably the best on the internet. Thanks!
THANKS Curt! :) I do my best :)
You are legend bro. I understand everything
Please explain a orb meter for me 😂 you are the only person that can explain it to me in a way I can understand
An ORP [Oxidation-Reduction Potential] meter measures your water’s ability to either gain or lose electrons in chemical reactions.
Oxidizing: Means the water can accept electrons, which often indicates the presence of disinfectants like chlorine or ozone, used to break down contaminants.
Reducing: Means the water is capable of giving up electrons, suggesting it might contain reducing agents like hydrogen sulfide or organic matter.
An ORP meter gives a single number in millivolts (mV), which reflects how oxidizing or reducing the water is, helping assess the water’s cleanliness and disinfection status.
Interpreting ORP Readings:
Positive ORP Value (e.g., +200 mV):
Indicates that the solution has a greater oxidizing ability, meaning it can accept electrons from other substances.
A higher positive value generally suggests a stronger oxidizing agent, which is good for killing bacteria or disinfecting water (e.g., chlorinated water).
Positive values are common in environments with disinfectants or oxidizers like chlorine, ozone, or hydrogen peroxide.
Negative ORP Value (e.g., -200 mV):
Indicates that the solution has a greater reducing ability, meaning it can donate electrons to other substances.
A lower negative value suggests the solution contains reducing agents like organic matter, sulphur compounds, or unoxidized metals.
Negative ORP values are often found in environments with decaying organic matter or polluted water.
General Interpretation Guidelines:
+200 to +400 mV: Water is moderately oxidizing; good for drinking water treatment.
Above +600 mV: Strong oxidizing conditions, suitable for disinfection (like swimming pools).
0 to -200 mV: Mildly reducing; often found in natural water bodies.
Below -400 mV: Strong reducing conditions, which could indicate the presence of contaminants or decaying matter.
For hydroponic systems, the ideal ORP range for a nutrient solution typically falls between +200 to +300 mV. This range ensures that the water is slightly oxidizing, promoting a balance between nutrient availability and microbial control. Here's why this range works well:
+200 to +300 mV: In this range, the solution maintains a healthy level of disinfection without being overly oxidizing, which can harm beneficial microorganisms or plant roots. It also ensures that the nutrients remain available for plant uptake.
If the ORP goes too high (e.g., above +400 mV), it may indicate excessive oxidizing agents (like chlorine), which could stress or damage plants. Conversely, if the ORP falls too low (below 0 mV), it could indicate a lack of oxygen or microbial activity, which can lead to poor plant growth or the development of pathogens.
Hope this helps!
@@Just4Growers thank you will read this a couple of times till it goes in but that is by far the best explanation of a orb meter. Much appreciated. 🫶🏻
So if I got this right, if you have a low reading would you either change res or add more hydrogen peroxide if you were running sterile rdwc? I want to fit a growtek dosing system and it has an orb meter. It’s going to be connected to the buckets so it can dose while it’s recirculating and be topped up by RO in the res. So I’m assuming I could put a peroxide on one of the dose pumps
You all complaining about talking speed? Instead of trying to get the channel to change to suit you, why not just watch the video again?? I've seen several of the channels videos multiple times and then ask questions to gain a better understanding. And I still don't get all of it. This is one of the two best and most informative channels on TH-cam for growing and product variety and reviews. It was hard for me to keep up the first time I watched one of his vids, but if I had quit at the beginning I wouldn't have learned anything.

how does .5 ec answer the question of that ppm scale to use lol
0.5 is the conversion factor, not the actual reading. So using this scale, 2.0 mS (EC) = 2000 uS = 1000 PPM (2000 X 0.5). If you were using the 0.7 conversion factor then it would be 2000 X 0.7 = 1400 PPM. As you can see, the conversion factor you use can make quite a difference so .... just use EC like those friendly, sensible Europeans.
okay that all makes sense so then .5 is the conversion factor for the Nacl meters?
call me dumb but im even more confused man i should have stayed in school lol is there a online conversion tool? i have a feeling im about to buy a 100+$ tool that im going to just sit and look at all confused that will end up on the shelf

OK, it did cover the subject, but in such a manner that the average person cannot make notes useful for later. It also did not provide links to printed material for later use. Their goal was only to show their knowledge, and I'll bet they didn't do it without notes.
Although humorous, ya might want to slow down just a tad. ;-) informative yet I am still lost. I just learned about "EC" & SIEMENS, MILLISIEMENS & microsiemens. I have a tds meter i need new batteries for. They are battery vampires apparently. However i dont recognize where it says what the conversion is in the barely 1 page paper that tells about it.
***** Thanks Kevin. A few viewers mirrored your comments so from now on I always strive for clarity before brevity. Happy to answer any questions you might have on the matter. Basically EC really is the way to go when measuring nutrient conductivity in the real world. PPMs .... meh!
Well i already have ppm meter... so... but it doesnt read past 999ppms. Im getting to understand it a little more. But still kinda scratching my head.
***** Well Kevin having a PPM meter is a good start!
I think of it like this: Water is a solute-in other words, it dissolves stuff. (I know, you knew that already! :-)) However, to really know what's dissolved in your water you need to see what's left when you boil it all away and perform lab tests for the presence of various minerals in the residue that's left over. You might find, for instance, that you have 75 PPMs of calcium in your water and 12 PPMs of magnesium in your water-but only a lab test could tell you that.
Of course, as growers, we don't need to rely on laboratories! We use TDS meters: Total Dissolved Solids. This guesses the total of all the different dissolved elements in your water in PPMs. 75 + 12 + whatever else is in there....
However, TDS meters are only guessing! They don't actually count up the calcium PPMs and the Magnesium PPMs etc... they measure how well the water conducts electricity-i.e. they are conductivity meters in disguise! Lol!
Pure water conducts very little electricity. However, as you dissolve elements in water, it can conduct more electricity. Thus, water's electrical conductance can be used to INFER the total dissolved solids in it. If our test water is conducting relatively large amounts of electricity we can safely assume that there are a lot of dissolved solids in it. If our test water conducts very little, we can assume it's pretty pure.
Different elements (sodium, calcium, magnesium, etc) conduct electricity better than others. So that's why different conversion factors are used-they are always guesses-but it gives us a good indication.
Growers in Europe skip this stage and simply use electrical conductance as a measure of how concentrated their nutrient solutions are. I'm with the Europeans on this one. They have one measurement to go by (in microsiemens or milisiemens) and don't have to worry about conversion factors.
So my advice-go get yourself a Bluelab conductivity meter (ask for 'the truncheon' but make sure it says Bluelab-you can't go wrong with this brand) and think of your nutrient strength in terms of electrical conductance rather than those pesky PPMs!
I'm happy to keep discussing this until it's clear my friend so don't hesitate to come back with any questions. Peace and happy growing, Everest.
Thanks. It makes a lil more sense. ;-)
We have been drinking RO water in our house for 30 years. I even tested for dissolved solids for my clients as a health professional. But we are trying to remove those solids from water, not add them lol.
Anyone know if you could measure the Chlorine levels or at least meter them using a TDS meter ?
I bought one of the Chlorine test meters from ebay :/ www.ebay.ca/itm/pH-CL2-Chlorine-Level-Meter-TDS-Water-Quality-Tester-Monitor-frSwimming-pool-spa-/311347766798?pt=LH_DefaultDomain_0&hash=item487dc5e60e
AND when I put some pink salt into the glass of water the chorine reading shot waaay up...
Of course the TDS meter reading also went from 15 ppm to 221 ppm.
The PH reading appeared good, I compared it to my Milwaukee PH meter and it was within 0.1 of the Milwaukee reading so I call that a passing grade.
I`m stumped, ether the Chlorine meter is crap or all chlorine testing kits do the same if you add pink salt...???
NoFear4XJs Hey NoFear. Thanks for your question. A TDS meter does not measure chlorine levels. It will measure chlorides such as sodium chloride but that's a totally different thing.
A TDS meter is just a conductivity meter with some onboard software to estimate / infer the total amount of dissolved salts. As such, your TDS meter will only change when you add solutes that impact the conductivity of the water, which most salts do.
If that helped please consider subbing my channel! Thanks :)
Bloody hell what a speed
This didn't start to make any sense until I toked on some Blueberry.
At 2:55 it says 600 milisiemens but I think it’s supposed to say 600 microsiemens
Thanks my head just exploded
I love your videos. So condensed knowledge. I thought most comments would be appreciating this but I guess not. But I love you. Keep up the good work.
+ankit patil Thanks Ankit. I appreciate your time.
you made me so confusede right now :O
+Happy Life That's NOT what I wanted Happy Life! Please hit me up with any questions. Happy to help.
Awesome, I love informative material on youtube that's to the point. Breath of fresh air.
Great video. I learned a lot.
Josh E Thanks Josh E. Please sub the channel for regular, educational videos! Thanks for the positive feedback. Much appreciated.
good info, but why are you talking so fast? whats the hurry?
Great content, but missed a lot of it because the information is coming at us way too fast. Cute graphics, good video, but SLOW DOWN. It's not cool, it's not cute, it's not effective - it's frustrating, very frustrating.
Jeanie Puckett just set your playback speed to 0.5 speed. Problem solved.
