The addition to this video including the fruiting phase, taste testing and further discussion will be linked above when its posted. The nutrients I used were the Flora series from General Hydroponics and also Armor Si. I decided to split up this video for the final phase because I will be including another time lapse and also have some talking points. Also because the answer was already very clear and no further testing is needed, at least for the vegetative stage. And fruit production in the aerated method is obviously going to be the winner.

Why didn't you notice all the fungus growing in the kratky one?
Pikudo Pikao there is no fungus. Those are air roots and the white on the plastic net cups is mineral deposit.
Pikudo Pikao at what point in the video please? I've watched several times, Is it really small? I would think its hard to mistake air roots, and I'm kinda curious cause I've never tried dwc without what looks like now, an extreme amount of aeration lol
Looked like fungus after you said it. the power of suggestion...
@colbys100 you can also add pondzym to water solution to add beneficial bacteria to eliminate root rot.
@colbys100 I control the slime in Hydro by adding the water, then first about 2 to 6 drops of Clorox depending on how much water you run I use 8 gallons and 6 drops. Let that run a few then add the nutrients like normal. The slime fungus is anaerobic and a very small dose of chlorine straight kills the hell out of it, like 2ppm and does nothing I to the plants. An old hippie told me this years ago and I have had no slime since, 10 or better years now.
lol i love how they party all night and sleep all day xD
lol commented the same. they get high lol
damn right lol
Bahahahaha! Was thinking that!
party all night.......
maaan why did you write this befor me?😄🌹
it would be good to have a separate camera in the water looking at the root growth.
That time lapse is ridiculously soothing! I've watched it about 5 times! Plants dance! So cool!
Love how the seedlings scan for light during the dark.
This might be the best video you ever uploaded!
The timelapse alone is worth watching and your presentation of the results and the explanation are very good!
btw: I Think i can see air-roots on the Kratky plants (the stuff that looks like mold :D)
Dave yes. That’s correct. What looks like mold is the small capillaries. the roots have increased their surface area to breath. They are also great for nutrient absorption like what I notice in my planted fish tank, but the fish like to pick at the fuzziness and end up ruining them. Interestingly, I don’t see much of that “fuzz” in Dwc even above the water level.
I think the DWC plants dont need the air roots because there is plenty of oxygen in the water.
Where do I buy those square containers you use?
His containers are cat litter containers painted black. He mentioned that in the basil video.
Pete I absolutely love those. we have 6 cats so they are a gardening dream
BTW I saw a recirculating DWC kit on Amazon no less made of the same buckets lol.
The plant was like " oh no where's the light" when it's dark and goes panic dancing. Hahaha
Great video! I appreciate people like you who go through the time and trouble to do these experiments and then publish them. Thanks.
It's really interesting that the plants anticipated the lighting cycle and moved around in response!
Kratky works best if you set it and forget it. Keep it closed to keep vapor inside. Opening it all the time means you ensure air pruning will occur, which diminishes the whole purpose of kratkys method. Keep it closed for water vapor build up. Only adjust or replace solution when it’s almost used up. Best for short term herbs
Where is your video showing this? I couldn't find it.
I suppose if it's really hot making it humid inside container?
I forgot to mention how much me and my son loved watching the "dancing" plants I guess dancing plants are happy plants! You did a great job with the photography!
It took my half a decade or more to realize how important it is that as many small bubbles need to reach the surface.. Magic little bubbles, i call them.
They get cranky knowing bed time is soon. 😆
2:39
What if you introduced a third bucket with just a flow/circulation pump?
Ohh How AMAZINGLY Beautiful! Thanks A Million; for Sharing! ❤👑
I like how they weeble wobble around at night time looking for light :)
WELL Done Sir! VERY well put together and explained ...
✌️❤️😁
Awesome video man. That timelapse and how plants anticipate light.. Really cool.
excellent & very informative video. amazing movement in the time lapse,
that thing grows like a monster xD every day it got like an inch taller lmao
1 Month, pretty fn amazing
Excellent video and the results match my experiments. Aeration makes a huge difference and thanks to this video I now have a better understanding of why.
Love this video. Love time lapse plant grows period. Thanks for this.
Scary big. Appreciate your efforts,thanks :)
I’ve used Kratky for one season and it was amazing for leafy greens. A key component was ensuring that the water level was even with the bottom of the net cups at the start. The roots were astounding, tearing the net cups apart in some cases. I believe that is why your Kratky plant did so poorly. I suggest trying the experiment again after making this adjustment.
but how does that explain the massive growth compared to the plant that did reach the (unaerated waterline)?
@@gr8belayr It doesn’t really, it’s just two separate experiments with very different results.
I was wondering if there was another explanation because I have watched several videos on YT with completely opposite results. In most cases roots are definitely more, but the plant itself grew bigger. I'm not an expert, so I was sitting here scratching my head trying to figure out why his experiment didn't work like the others.
@@gr8belayr It is explained on the video...
Great video! Do you happen to have the links to the containers you used for the plants?
Many thanks for going through the trouble of doing this experiment and sharing your findings
Plants swing as they are looking for something to hook on and spend less energy staying straight against the wind
Thank you for doing my homework for me- new sub here
I work at a place that sells hydroponic supplies and you explained to me in 6 minutes what I have not understood in almost 2 years of working there! Thank you! Also, it was a joy to watch the plants dance as they did. I had no idea they did this! I knew they followed the sunlight, but didn't realized they moved in such a beautiful way, especially in synthetic light. What a treat to witness that!
Roots love oxygen! I grew aeroponics,and the growth rate was unbelievable.
I was going to use ebb and flow, with hydroton. What would you recommend please?
@@mrtechie6810 Ebb and flow is good.But you just need to make sure the water you give is well aerated.Aquarium bubbler,or just a pump that keeps water moving.Water as it goes against the receptacle its in and travels back down takes oxygen with it.
Use this in your storage barrel before you do ebb and flow to increase the oxygen.
@@djyul thank you. I put a 50 liter plastic storage box with a tiny Atman water pump, facing up. I added some baskets that are just touching the water surface. Then I made some trays with covers that have holes to put plant pots in...figured to pump the water from the box into the trays using a timer, and let it drain back.
I placed them under a large window. I already have peace lilies (need shade apparently) and spearmint. I would like to grow these, plus strawberries, basil, and ginger (I have a piece rooting in tapwater).
I am about to buy the nutrient concentrate and media. Looking at General Hydroponics 3-part; hydroton and pumice.
I am new at hydroponics...I really appreciate any advice you can give me!
@@mrtechie6810 If you are new to Hydro,1st bit of advice is KISS! Keep It Simple Stupid! Not saying you are stupid,just what it means.
2nd,your water container needs to be closed to slow down evaporation.Keeps EC and Ph more stable.
3rd,RO(Reverse Osmosis water)This has a very low EC,0.003 if i remember correctly.
I gained my knowledge growing weed,and using rooted cuttings.These can not take any more than 0.9 EC(EC is the amounts of salts in your water)Normal tap water has an EC of about 0.8,which means you can only put 0.1 nutrients in the water.
But if you mix RO water with tap water it gives you an EC of about 0.3 which means you can give 0.6 of your desired nutrients.If you give cuttings more than 0.9 they will die!
4th,Light,this is important,the ratio of light to the ratio of nutrients is something you must discover yourself.But where 1 guy is using 4x1000w lamps in a 4sq mtr grow space,his ratio of feed will be higher than someone else who is using 4x600w lamps on the same area.
5,Good ventilation,is also important and a movement fan to stop mildew from starting where leaves start to lay on each other.
When you get it right,they grow really fast,and healthy!
When i started growing years ago there where no liquid feeds,just granulated.I used to use Peters,dissolving in warm water and then adding to feed water reservoir.
You need to buy good quality EC and PH meters!!!! And keep them clean rinse off after use! Add your feed to 1 ltr water and test! Then x that for your 50ltr reservoir.
When you have problems with your plants always check the PH and EC first.And also you must check the calibration of meters reguarly,or when you make a mix that you normaly use and it doesnt come back with the reading you expect.
Its not called EC now,was when i used to do it.I am not sure but not all feeds will be good for all types of plants,you need to check this!
Good luck with your venture,hope this helps.Peace
@@djyul thank you very much for your advice! Yes, I rebuilt my old RO unit and it's plumbed to a float valve. I have a TDS meter and a PH meter.
I had been propagating corals, so I am highly experienced with water test kits, dosing macronutrients and microelements manually or with a timer, CO2 vs PH, lighting vs metabolism, water oxygenation, etc.
In the past, I also kept angelfish in freshwater planted tanks.
I need to learn the rules for keeping these plant crops, as I have not farmed these before, even in my garden.
I tried using regular fertilizer for hydroponics, but I suspect it is deficient in calcium and magnesium and likely in iron too, plus skews the PH. Unfortunately, I discovered that my test kits are only for seawater and not for freshwater, so I would have to buy a different set of test kits. So I decided I should just go with a proven nutrient product made for hydroponics (e.g. General Hydroponics - GHE softwater), and use it for a few crops until I see good results, and only then I should start experimenting with cheaper products, mixing my own chemicals, testing instead of replacing all the nutrient solution, etc.
There is a ceiling fan in the room. And I have a "swamp cooler" evaporative humidifier and a hygrometer. Trying to keep the humidity above 50% on the dry (35%) summer days that we often have here.
As far as illumination, I hope I can use the natural sunlight that comes through the living room window. It measured around 25,000-30,000 lux, if I recall correctly. This would make the plants grow in one direction...not sure if that will be a problem?
Thank you for all your kind advice!
That was an awesome time lapse man. Thanks for sharing that, and your comparison.
It's so cool to see something in a different time - like we could never see in "real life"/real time. It really does show you things you could probably never notice otherwise.
The way the plants moved, in circles, during the lights out phase - and how the began to anticipate the coming darkness or searching for light, change in environment or whatever exactly they're doing is fascinating.
Many useful information. Excellent time lapse. I had already in my mind to use aeration, now i am sure. Thank you for the video. Regards from Germany.
That was amazing! I’ve never seen plants dance like that. I’m going to look into those cameras👍
Can you compare air pruning containers vs those with only few drainage holes
I’ve used the cloth type. They work very well. You can also cut a bunch of holes in a plastic container and line it with landscape fabric to get the same result. No winding roots to speak of and they all become very small and fibrous.
I at one time had two 8 site hydroponic units and I absolutely had to put aerating stones in every single plant site and also the nutrient mix. The one time that I did not have that going I ended up with root rot. With the air in there never saw root rot again.
waht about ebb and flow?
Ebb & flow is a good system too man, i first started with an e&f system in the early 70's. Used hydro corn as the growing medium and ALWAYS had great results but to me personally all food & herbs taste WAY better in soil mediums brother.
what is aerated nutrient solution
Good one,1 of your best video's ive seen that u have done, keep up the professional quality work!!!!!
Thanks for the valuable information........
Can u do a video kraty method with a ultrasonic Mist maker in the tub, I haven't had time - ( dealing with work) - for the experiment it would be a lifesaver if u did it, just to know if it works then i could move forward( anyways aren't you interested if it'll work and what kind of growth it will produce???).........
Thanks for the video that was amazing
Where can I buy the black containers with the hinged lids that you use, please?
I'm scrolling through the comments now to find out the same thing
2:12 what happened to the baby plants.. the innocent baby plants..
Hail The Almighty Lord of Hydroponics Kratky
Even though it's only a 2-plant experiment, that's a significant growth difference that's unlikely to be due to genetics. Great work pal :)
Gary McKinnon 4 plants per bucket. Thanks
@@GrowingAnswers I missed that, thanks !
You are incredibly handsome. I mean helpful. Nope, definitely meant handsome.
Maddie Kelly thank you
Amazing presentation, great experiment, and I love the time lapse, especially the plants dancing when the lights go out :-)
We should show this vid to all vegetarians that try to make us feel guilty for eating meat, show them this dancing plant, so they know they are cruel too to eat plants. 😂😂😂
Amazing video, thank you soooo much for all your efforts. Really really appreciated!!!
Fantastic. I've found my best results with chillies (scotch bonnets, habeneroes and jalapenoes) have been in flood and drain in a hot conservatory in the UK that hits 110F in summer.. They love it They seem to hate DWC. Been playing with basil in the same area in dwc vs outside in soil.. It's all about experimenting with what works in which situation.
I'm about to start a system...was going to use ebb & flow. What do you recommend?
@@mrtechie6810 Each has it's own advantages. Aeroponics is great as long as the pump or power are stable. Ebb and flow gives you a bit of leeway. If the power goes out you have a few hours. NFT I find hard work but still experimenting. Dwc I prefer for seedlings and starting. I would recommend ebb/flow to start with though.
Best video...and perfect experiment...
Really we all should appreciate your work
Mann, love the thought you put behind this video.
Thanks for the video and your observation on how things are different with the air stone and where the placement is a bunch of the root mass when they're both in the same containment
when night they're party
Excellent Demo! For those who do not know, Dr. Kratky was looking for a way for poor, 3rd world country gardeners to grow food with less than optimum conditions such as poor soil, (or no soil) limited funds and limited water. PS After using air-stones over many weeks/months, I have had air-stones become clogged with solidified chemicals. Most likely caused when the air pump would shut down at night allowing some chemicals to enter he stones and crystalize. Thank you for this well done experiment! It's fun to watch time lapse growth.
Night cycle is a terrible name....unless it's a movie about a motorcycle that comes to life at night.
...and solves crimes.
Hydroponics is a Nightmare with PH balance control , Temperature control , nutrient levels , Algea , Water Changes and Pumps ! Plus daily Monitoring ! ...... Stick to Dirt ! ... and invest your money in Lights ....... KISS !
Well done videoclip and great information to know. It's nice to see a scientist at work. Thank you for sharing.
Thanks for sharing the knowledge
Wow your videos are perfect, I very rarely comment, but had to, thank you very much!
Wanna REALLY supercharge those results? Try a cheap fountain fog maker. It creates both a fine water vapor that fills the chamber and allows excessive fine root formation, but also slightly warms the water with its energy. You will be blown away. They can be purchased cheap too.
What a great video. I'm relaxed, and informed. So much time saved. Thanks
Next time get the plants root bound in coco then slice off the bottom and drop the plant in. Kratky works much better that way not sure about DWC tho would love to see.
it would be interesting to see aerated vs "non aerated with an internal pond fogger" to prevent the other subject from air pruning.
Fascinating, loved the time lapse video. Great watching how the plants move. Thankyou, really enjoyed watching, and great experiment.
I love your videos..so interesting..very helpful..God Bless❤️💞
really calming watching plants grow. thanks for the video. had no idea i would enjoy this. not even sure why it was recommended to me. but thanks
I like your content, thank you for sharing.
now step it up and compare hydroponics aeration to just pure misting aeroponic and see the diff!! and saves 80% the water usage the only problem 24/7 baby sitting
He over complicates everything ...but good video my guy lmao
Those timelapses reveal them dancing 😂 looks like they have a head and arms and are doing some sort of sun dance 😂
Remember when you were a young sprout?
Those Thai hybrid are ok, not really that hot 😁 but I guess living in Thailand and eating 90% Thai food and never asking to put less chili's in my food has toughened me a little bit 🥳😋😅
Plants do have clock proteins. Many plants use them together with temperature to determine when to sprout.
SUPER interesting, thankyou!
My grow tent has mostly aerated DWC
but i do have a few kratky as well, and the aeration plants
for years btw... have always done better
the number of people on here saying otherwise are disingenuous or liars.
Forget the plant, I wanna see him dance!
From 2:13 you can really see how the plants could actually globally be creating the wind like a worldwide Mexican wave MIND BLOWN
Nice timelapse, good info :)
Awesome vid! Really appreciate you taking the time to share this! First time I've pushed subscribe...not sure what that means but I want to learn and see more!
So pleasing to watch
Sweet !! great upload. Thanks for the info and awesome job btw. :)
Make some plant dancing videos!!
Then expand! Create a competitive plant dancing tv show. Call it
“Plants Got Talent”
“Dancing With the Plants”
The plants panic in the darkness
Plants: WHO FUK*NG TURNED THE LIGHT OFF!? I CAN"T SEE A DAMN THING!
I need to know where you got your containers!!! I've been searching for these for some time now and can't find them!
Travis Menninger th-cam.com/video/kU891LPvEzc/w-d-xo.html
@@GrowingAnswers thanks! Now if I only needed kitty litter... haha
That's incredible man thanks for your research!
Awesome vid. The plants seem to do all their growing at night. Interesting
hey ,if anyone else is searching for
pdf aquaponics system
try Proutklarton Surviving Instruction Plan (do a search on google ) ? Ive heard some extraordinary things about it and my friend got great results with it.
Am I only one seeing those bars in the timelapse? I am not complaining , this footage is incredible, I'm just wondering why I see light bars
Light frequency interfering with frame rate
Growing Answers maybe changing the shutter speed would help?
@@HandleBar3D can’t change the shutter speed on the time lapse camera. It’s fixed automatic. It takes a picture per chosen interval only. Aperture is all that can be adjusted which helps a little.
Really well done video. Really liked the time lapse. Good stuff.
it actualy adds dissolved oxygen not ‘aeration’ to the water through breaking the water surface with the bubbles.. get recirculating you will see real fruit ✊🏻✊🏻
Have you ever heard of a Dewey Mister? They're about 18 bucks, they are a sort of cross between aeroponics and dwc. All you need is an air pump and the Dewey, no air stone required because the roots are not submerged.
www.amazon.com/Global-Garden-Friends-Dewey-Mister/dp/B00J3CYQ38
This is video is tells everything. Awesome! Thanks for your effort man.
I'm trying to find a true aeroponic system but seems like they almost dont exist only "low pressure" aeroponics which is in my mind still hydro. I'm looking for any systems that run 10microns and under. I was thinking of combining the too. Of anyone can point me in the right direction would be great.
Good job.
Also use CO2 up to 1200 PPM, they will double in size just like the pot growers do !
how can we do that ?
有研究表明短期内会增加光合作用产物，然后就是生长停滞的副作用，类似于人类服用过量兴奋剂。不过我也想亲眼看看到底会怎么样
Thank you for the Video. Just curious, where did you get those container with partial lids open like that? So cool. If you can send me a link to your affiliated site I am most grateful. Thanks!
I think the plants "dance" because they are using their leaves to search for light. Once they find it, they stop dancing because they know exactly where the light is.
thank you sir! this video helps a lot for those starting a business.
Picture's worth a thousand words. Excellent video. Thank you!
Who cares about pH, or ppm. What did people do before this technology was around ? Did farmers and gardener's not have a garden ? Did nothing grow? Is mother nature a ph pen? Or a ppm meter?
May I ask what you are using for containers? I've been trying to conceive of cheap and effective means for the storage of my own hydro plants. I've been thinking that I could re-purpose used cat litter containers which greatly resemble the containers you have used in this video.
they appear to be old kitty litter containers painted black.
Not sure if using the same fertilizer in each bucket is fair. The aeration affects ph, and maybe another fertilizer will work better for the kratky. I know this is an old video.
I like it when the lights turn off they spin around like a radar looking for light. That is kinda scary. I didn't know they moved that much.
Subbed! Thank you for this great content
