Ebb and flow (also known as 'flood and drain') is a simple hydroponic growing method that's cheap and easy to set-up and relatively hassle-free to maintain. Growers enjoy bigger yields over hand-watering and are freed up from the chore of daily manual irrigation. We explain everything you need to know about ebb and flow in under six minutes - check this out! - แนวปฏิบัติและการใช้ชีวิต
THANK YOU SO MUCH!
I've Looked n Looked at about a hundred websites n Utubes to find a Complete Guide to Ebb n Flow and you were the only place to have it... thank you again!
I love how this is a video about gardening and the top comments are all Splatoon
LOL
Right
Best video ever, short, sweet and straight to the point! Thanks!
25yrs later still hard to beat . Was cool to see the GH there too.
Just bought my first table. 2x2 from hydro farm. Hope to get it going this weekend! Re-watched this video for info. Thanks again!
Your knowledge is so powerful, I love that you freely share it
Thank you! And you’re welcome. Uploads start again from next week.
extremely informative...no babbling or excessive 'uh's' as with most how to tutorials. Great video
subscribed because Fahrenheit was converted to Celsius like a true gentleman
Thank you! Appreciated!
New splatfest looks tight
Hey man, super fun video to watch. A lot of information as well, I look forward to learning as much as I can from you.
+WiFiCannibal Glad to hear it amigo. Hope you're subbed!
Very informative. lots of great info presented in a quick precise form. subscribed
Thanks for your subscription and feedback Tom - much appreciated on both counts. Thanks again.
I really enjoy listening to you. You have got a lot of knowledge and you're so funny! All the best from Germany!
***** Danka! I'm really happy that you enjoy my videos. Thanks for subscribing too! :) I appreciate it.
After many research and watching this video I understand am in right way to start my grow rooms with EBB FLOW,many useful data in this video for me,thank you👍🏽👍🏽👍🏽👏🏽👏🏽👏🏽💐
Great video! Thanks for sharing with us.
So concise and perfectly helpful. Gracias amigo!
De nada!
Thanks, that was very, very thorough!
I love the way you talk man!
Awesome Video. Very informative and well done
Excellent video, right to the point. Wanted to try this system growing some watercress.
Using bato buckets now for tomatoes, cukes, zucchini and peppers.
Wis.Gardener Thanks Wis. You can grow pretty much anything you like in this system. It's so reliable! I highly recommend it. Very simple to set up and maintain too.
I'll have to watch this one again!
Great video....is drain to waste a better option. Can you discuss the pros and cons of different hydro setups. Flood and drain. Drain to waste. Dwc...etc etc...subscribed and liked. 👍
Great video! I have not tried this but now I want to... So many things I want to do
Tim Miller You definitely should Tim! Super easy to set-up and very productive! Let me know if you decide to take the plunge. :)
For the price of a menu at McDonald's you can set this up in your home
God I love your videos! incredibly helpful and informative! keep up the good work
+MYCO2bag Awesome to receive that kind of feedback. Thank you Myco!
Hot Damn Splatoon is looking alot more realistic in this video
I find this disrespectful. Get out of my house,
I have absolutely no clue what’s being discussed here. Lol.
@@Just4Growers there is a game called splatoon 2 and inside the game is a song called ebb & flow
Mlgdoge 69 Thanks for the heads up amigo.
Love how you breaking down the math and this
This to the best song in the world. How do Nintendo do it 😂😂😂
🥀👍🥀
Nice setup
awesome video! Just what I was looking for. Thank you!
+tanman1991 You are welcome Tanman. Thanks for taking the time to comment. Hope you subscribe to my channel. Thanks again.
Hey there! Super cool video with lots of information. I'd like to learn to which tank you connect your bluelab guardian probe to? Do you have one big tank for collecting the water or several? In this case do you use more than one probe? Thanks so much :)
Quality video. Thank you.
Ur an a angel. Loved the way u explained it.
Thanks Fayez. Some of my highschool colleagues might well take issue with the "angel" label but I'm accepting it with open arms. Thanks again.
Nice and quick run through.
+Ha Dang Thanks Ha.
Everest Fernandez This makes no sense to me because the drain is higher than the water in every diagram I see wtf lol what am I not understanding
One is the overflow drain valve and the other is the fill valve connected to the pump which is set closest to the base. Once the pump shuts off most of the water will drain through the "fill" valve back into the reservoir through the pump.
Hi! So I'm currently setting up an ebb and flow system with actually the same tray you're using here. I see that you're using one of the deeper wells for the inlet, and the other diagonally across for the overflow, is there an advantage to this positioning compared to both fittings being in the same well? Each of the two wells seems to have two nubs for fittings (drilled from the bottom of the tray) Thanks again! And great video.
I have grown in hydroton before and am going to do it again. This time however I got a tip from someone saying to just fill the whole tray with hydroton and plant your clones directly into it. It will develop a much better root system than even with baskets. Plus its reusable and we try to stay as green as possible. I love Hydroton.
+Ted Dekens Yes Ted, I couldn't agree more. I love hydroton. It's particularly good for plants which enjoy good drainage and a well-oxygenated root zone thanks to all those tiny little gaps between the spheres of clay. I've tried the "filling the whole tray" method and it works great! Uses a hell of a lot of hydration, for sure, but-as you note-it can be easily sterilized and re-used. (Something I'll be sure to make a video about at some point!) Another downside, of course, is that your plants can't be easily moved so it takes some skill and precision to dial in plant numbers and vegetative periods so that you get a nice full, even but not jungle-like / overly-competitive canopy. As for the plus sides, well you already know them! All that hydroton is like a luxury crib for your plants' roots! They are not bound by pot size any more! How often do you find you flood the table when your plants are mature? Once every 30 minutes, or every hour, or less? My one main tip with running a system like this is to air-prune your plants' roots in propagation stage so they are literally like race horses busting to get our of the starter gates! Roots everywhere coming out of the net pots or starter blocks, whichever you use. Anyway, thanks for stopping by-hope you're subscribed!
Your German Accent is impressivly accurate :D Greetz from GER
WOW, you killed that video man. Subscribed
Kif Dawg Thanks amigo! Every sub much appreciated!!!
Thanks for the passionate lecture.
I have a question. Some people put LECA balls on the surface of the EBB bed. Is there any reason for doing that? Is it necessary or recommended or not that worthy for?
I like to have circulation in my flood bed. One big advantage of Ebb and Flow systems, which wasn't touched on in this vid is salt removal. With some kind of circulation not only do your plant get extra oxygenated water, but more effective salt removal. So I've come accustomed to nice, deep floods. I think a mechanical timer is fine if your using a circulation jet, or forced bubble jet imho. Examples in my vids. Very easy mod.
Yes salt removal was mentioned here actually
What size of res. are you using and what size do you recommend for a 4X4 table? Love your vids.
I'm growing a lemon tree.. what do you suggest I use (clay,lava,rockwool,etc.) In my grow tray?
First grow i ever had was a flood and drain. This was before there was a hydroponics shop on every corner so i had to make my own from scratch.
I started with a deep water culture, as it is even simplier in setup. I've had the biggest yields i've ever seen!
But there are some parameters that you need to watch carefully.
1. humidity (provoked mold/fungus) 2. ec and 3. ph that becomes quite unstable the bigger your plants are and the more they suck.
Jeez... I should have brought a pen and paper. Awsome bud.... I’m growing outdoors in the I.K... can I use my own pond fish but will I need the nutrient reservoir?
I've been using ebb and flow since the 80's and it's the only way to grow. Plants grow like some sort of plant monster in a Japanese anime movie. General Hydroponics is the cheapest fertilizer I can find and it works great.
Nice video mate. Just need your help/opinion. I'm developing an "Ebb and Flow" system but instead of using a timer, I'm trying to use an umidity sensor which is in charge of switching on/off the pump. Even during the hot days in Brazil, my media ( rockwool) is getting wet for a couple of days, so my pump is off for a couple of days. I'm growing pepper, which doesn't need too much water (as far as I know). My question: For which plant do you recomend flooding the system "1 to 2 times" per day? (4:13min).
I also saw on your video that the "drain process" helps to "push" fresh air to the roots zone. The fact that I'm flooding my plants once or twice a week, doens't help my plants to getting this fresh air ?? . Thanks for your help.
15 minute feeding does work. I've seen it done. Pot size and plant size come into that equation as does the power setting on the feed pump. EG: If you run the pump at half power than it will take twice as long to pump the nutrient and the plants will receive roughly the same amount as they would running for 7 minutes at full power pump pressure. As long as the plants have drained fully and the gap before the next feed is long enough it will work. It's not ideal but I have seen it done and I know it works.
Bro this song is great
From my experience, 15 minute flooding isn't too long. I had the eco100 for a 7 gal system with hydroton pebbles, flooded my roots 3 times per day (4 times when plants got bigger) for 20 minutes each flood, and they grew just fine. The exact timing of lights and feeds aren't that important either. If you think about it, in nature, when it rains, it is usually cloudy, and can be for several hours as it rains. Sure, the plants have sun exposure after the rain when the ground is still wet, but plants can grow with multiple consecutive rainy days with significantly reduced light. It can also rain at night. Maybe it's optimal to time floods with light, but far from necessary. I haven't tried timing my floods with lights, but I would think timing it shows diminishing returns. The key for hydroponics is having the nutrients readily dissolved in water, rather than have it be in the soil and waiting for rain.
I thought the same. I have seen plants be propagated, even tomatoes being left in water for 2 weeks. Those roots don't rot. What's an extra 10 minutes or more. Especially when you look at kratky systems
Im going to use the raft method. Can I have a constant flow?
this to me looks to be the most cost effective ebb and flow system.
how long does it take when turning on the pumb and off? What is your suggestion of your system?
Is a tray full of rockwool cubes a bad idea? Will the rock wool cubes drain effectively enough or will they hold in too much water? Also, ive seen people using just plain 4x4 rockwool cubes sitting in the tray...in this case where do the roots go?? The plants finished with great results, did i miss something?
I notice most Ebb and Flow systems don't have covered reservoirs, meaning light is always touching it, does this not promote Algae and root rot? Some videos I see with Ebb and Flow have lots of algae in the table but plants seem healthy?
Great job
Thanks John.
I've seen some flood trays completely filled with hydroton. Is there an advantage to filling the whole flood tray with hydroton vs using say fabric or plastic pots (like you have used)?
Thanks.
yes, the roots can fill out the whole tray
set up time best for anthurium? thank you
Excellent information greatly presented. I liked your monitoring system , looks expensive.
lizardspiral Hi LizardSpiral. The Bluelab Guardian Connect isn't bought with pocket-change, that's for sure, but boy does it save me time-and I love the fact that it logs my all-important data to a spreadsheet, on my computer and up on Google docs if I wish, meaning I can check in on my plants from anywhere. Next step after that is a pH dower, that's for sure!
Hey Everest! i just purchased my Bluelab Guardian Connect and would really appreciate if you tell me how you had it log data to your computer! PLZ
how does the pump know when to turn off. is this suppose to be on a timer
Hi Everest - what do you have your Guardian Connect Stick plugged into? Old Computer? My understanding is that it ALWAYS has to be turned on with software running to log the data so I'm thinking through the ways I can do that, ideally without spending a ton of money on a computer I use for 1 application!
cool vid, thx
Great video! Is it acceptable to use a bell siphon in hydroponics like you would in aquaponics?
Sounds like a good idea
Is there a webiste. Where i be able to find trays liks those. And the growing media where can i find tht
When doing mmj clones from 1" rockwool how many times a day must you flood and drain? 10 mins flood each time? lmk and thanks!
Do you have to flush your plants after 3-4 days of watering with liquid fertilizer?
Hi, Your videos are very useful. Great work.
Do you any other supplier of EBB and flow Tray?. Because the one you suggested is not shipping tray to India.
Please let me know if you have any other alternative. Many thanks.
Thank you Chand. All you really need for an ebb and flow tray is some kind of plastic tray with 15 cm high sides. Then all you would need is an ebb and flow / flood and drain fittings kit and a drill to make holes at either side to accommodate the pump inlet and overflow drain respectively. If you need help finding the fixtures and fittings let me know.
Hey Ev, do you have a preference for how high up the pot/medium the flood water comes to? Thanks 🙏
The entire root zone, and no higher than the top of the medium (so the top stays dry and can't form algae)
how much irrigation in 24/7 hours ? For example coco coir or rockwool?
Great, thanks
Can you do an auto pot video good sir 👌😎👍
Hey there man. Love your videos! Quick question, for a 75 gallon rez how many gallons per hour should I be using for my submersible pump so im not filling my flood table up up too fast (my flood table is 3 x 8)
Carl O'neal 300 GPH would be my minimum. Nothing wrong with a "quick" flood cycle! Glad you're enjoying the vids. Thanks!
Massgrowstv ❤'s this!
My first table , 1997 hydro farm
It was orange I think .
Wish I still had it !
so..... I really want to fully crack the "ebb and gro" controller, but, in the mean time until I can find some actually fruitful info on it, this may be a more practical rout. so would a float switch to shut the pump off when overflow level is reached be an effective means to control the flood and drain? a digital timer may be a bit difficult to obtain, but I can probably get those rinky dink dial style. anyways, this was worth a sub to me, so you got another follower bud
How can it drain if the overflow pipe is higher than inflow?
I have been looking to start a garden but I live in El Paso. My home is located in a very sandy part of the city. I have watch a lot of your videos and would like to know if the Ebb and flow system would work great here in the dry and hot clement of Texas.
+Faheed Alajmi Outdoors? Yes. Depends on what you want to grow. Season is key with your climate. Your mild winter would be a great time for leafy greens, lettuce, cilantro etc. Your summer's get very hot - so I'd recommend going BIG on reservoir and think about how you're going to try and keep it cool and well aerated. If you can keep their roots nice and cool you'll win. Try fabric pots with 70/30 coco/perlite mix. Just base nutrients. Keep it simple. Indoors: yes, you'll probably need an evaporative cooler if it's always 6% humidity in El Paso like the weather says today! I thought my neck of the woods was arid! Happy to learn more about your plans Faheed. Peace and happy growing, Everest.
Thank you, new sub🤟🏽
Mr Howto Thank you and welcome!
Hello, greetings from Argentina. Of all the systems that you could try, which one do you recommend the most?
If you are a beginner try a modular system or a flood and drain tray with pots on it so that you enjoy some flexibility when it comes to (re)positioning your plants throughout the lifecycle.
Try to find the raised table 4×4 hahahah Amazon's sold me a 4x4 its 53 inches send it back. Certain things they have in lockdown so I used to chop saw I think I had to cut it in eight different places grind it down mig welded all better. As far as the pump goes on the 4x4 I used the bottom feeder otherwise you leave 10 gallons behind I keep the perfect amount of water in the reservoir just so it can keep overflowing gently. 560 gallons per hour lol two and a half minutes of school had to get a digital timer 10 minutes to pump stays on
Anybody knows a cheaper alternative for the bluelap connect? The cheapest i found is about 411 euros shipped from US including taxes and shipping. If there would be a cheaper alternative brand idlove to hear it.
What's the better between a well setup flood-and-drain vs. a well setup deep-water-culture?
Salad - DWC, Tomatoes - Flood and drain.
It all comes down to plant requirements and optimizing the conditions of their surroundings.
Where did you get that shallow inlet??
Anyway examples of this done on a commercial scale?
All very easy to make yourself like all hydro systems are.
I know this is an old video, but I had a quick question. Is it ok to use aquarium stones in the tray to take up empty space? I don't want anything that will absorb the water/nutes, and that's the best I could come up with. I'm very open to any other suggestions too, just don't want any pouros/absorbent materials.
hydroton
Great video! Can you please put the link for Blue lab guardian. Also can you use growstone / hydrostones. Lastly do you have to run the ebb and flow system throughout the day 24/7? Thanks once again.
+Alex Pratt Hi Alex. Good info on BL Guardian Connect here: www.getbluelab.com/shop/By+Category/Connect+Products/Bluelab+Guardian+Monitor+Connect.html and es, growstones are on the list !
Everest Fernandez Thanks really appreciate your reply.
+Everest Great video and nice set up. Are those Squash? If so, do I have to Trellis squash? I have a very similar setup BUT when the reservoir goes up the pump seems to be struggling and making lots of noise. what do you think could be the problem?
+Debra George cucumbers - they need a lot more space than you might think! Lol. Trellising helps, esp indoors! :)
Cucumbers! !! Ohhhh. Yeah. I know about those. BUT Squash, NOT sure. Lol. Happy farming.
1. Good video. 2. Does ebb & flow work outside hydroponics? For instance would growing seedlings in potting mix benefit from an ebb & flow schedule?
Karl Fimm Hi Karl. Great question-thank you for asking. YES, you certainly can use ebb and flow for seedlings and mature plants grown in soil / peat based potting mixes. As well as giving you some of your life back, this method also allows you to use organic nutrients if you wish-especially the types which are more prone to clogging drippers. I would recommend a nice light potting mix with plenty of perlite or vermiculite. I would also choose fabric, breathable containers or root trapping plastic containers for increased aeration. Yes, these types of containers oblige you to irrigate more often, but that's hardly an issue when you've automated the process! :)
Incidentally, I am in the process of making an ebb and flow propagation tray right now! Once I have it dialled in I'll summarize it all in a video. Thanks again for your question and please consider subbing the channel. Peace and happy growing, Everest.
Karl Fimm PS You can find my outdoor modular ebb and flow experiment on my channel. I live in an area that receives very little rain, especially during the summer months. Rain can interfere with nutrient solution strength, pH, tank fill levels, and electrics! You could grow under a roof shelter (i.e. roof and pillars but no walls) for maximum protection and ventilation.
Good useful
danke
Achtung! this was awesome
Hi, great video thank you, I do have one question.. do you pop a seed straight into the say rockwool or do u germinate elsewhere first, many thanks
Yes, most growers using propagation cubes - rockwool is great for this purpose.
thanks @@Just4Growers , so literally just put the seed into the rockwool and into the ebb and flow system. Ie you dont germinate somewhere else before putting into the ebb and flow system
@@keithbennett6422 Sorry; no - you should propagate first under low intensity diffuse light. Ideally, wait for the seedling’s roots to have fully colonized the propagation block BEFORE transplanting into an egg and flow system. Same goes for all hydroponic systems. USE the block - rockwool is such an amazing substrate -:) hope that makes sense now,
you should check out VaderOG. when emptying out his res. he uses a water pump that can connect to a water hose and a water socket. would make your change outs a snap
it's a medicinal herb channel but good stuff
I know this is old, but at around 2:00, he says you need both holes at the lowest end of the tray. But, his holes are in two different spots?
Hi Jemmy, arguably you can put the input anywhere you like, but the drainage should be where the water naturally pools - as you can see I’ve got lots of ridges on my tray, and the molding is cleverly designed to channel the water to the drainage point.
What are the timers you using that can do 15 minutes intervals? The ones in my local area can only do 30 minute intervals. Thanks
Timothy Paul Just standard segmental timers bought from a big box store amigo. I’ve seen the 30-min sort too, but 15-min is more common. Better yet, get a digital timer and enjoy per minute / second precision!
I feel bad for the people that are actually learning about this and all these people from splatoon that searched the song up that has the same name as this.
hi i have ebb& flow system with rockwood , please help me how many time can i flood my system a day eacht time with 15 minutes..?
+Minh Tran quang So many factors involved Minh, but you should try to determine when your rockwool is 50% dry (50% of its saturated wet weight) and re-irrigate then.
I heard "mature" root... so if I transplant. Should I top feed for hiw long
Wait until you see the first signs of roots at the bottom of the pot.
PowerGrow Systems You mentioned you don't flood just before the lights go off...I'm assuming you don't flood at all when the lights are off then? What's the science behind this? We get a lot of questions on this in our store. Thanks!
+PowerGrow Systems Thanks for your question amigo. The primarily reason we irrigate our plants is to supply water. Around 95% of this water simply flows through the plant (from root to stomata) - released back into the air as water vapor. The latent heat of evaporation (as the water leaves the stomata as vapor) is what helps to keep the plant cool. At night there is no solar radiation or grow light radiation - by definition! So there is not such a pressing need to keep the plant cool. A drier root zone also helps keep oxygen more abundant which is used (during the day and night) to fuel cell growth and other metabolic processes including plant the reformation of the enzyme Ribulose-1,5-bisphosphate ( C5H12O11P2 ) in readiness to form RuBisCO - an enzyme used to capture atmospheric CO2 once the lights come on again / the sun comes up. PS I visited your website's education / tutorial section and didn't find a link to this channel or any embedded videos! Just sayin' .... you're very much encouraged to refer to them on your website. I'll make a video on the day / night, wet / dry cycles if you like. Peace and happy growing to all you fantastic folks in Utah, Everest.
Wow! Afte that reply he couldn't even say thanks. Screw your store. Bet your customer service skills suck ass too
great video! do u have any experience with fogponics?
+nickjamesbitch2 Yes, a little! It's on the list.
Everest Fernandez another thing u should check out if you havent already is those ferris wheel gardens
+nickjamesbitch2 Ah yes like the Omega Garden? Wouldn't that be fun!
how do you get rid of brown algae in a hydroponic system? I tried 63 degree water, cleaning everything with chlorox and dawn, I even bought great white, voodoo juice, and hydroguard nothing is working for me any advice?
conentrated hydrogen peroxide, H2O2 (liquid oxygen), I use 32%. It's safe for the plant and breaks down into water in a few days naturally. Just use gloves and wear safety glasses.
