I've gotten this question so many times that it's about time I answer it on the channel! When growing in a Deep Water Culture (DWC) system, many people write in and ask, "Where should the bottom of my net pots be in relation to the nutrient reservoir?"
It's a good question, and the answer is pretty simple...so watch and find out!

Perfect timing I'm starting my first DWC grow and this was definitely becoming the last issue I wasn't fully confident in. Thanks for the information and I cant tell you how many times I've referenced your social media outlets for help.
Great Video!!! Do I have to cover the Mason jar so light doesn't penetrate?
Where is the Air Stone? How does it poke out the top to the pump?
Thank You!!!
Thank you!!! This is the question I always have after watching so many hydroponic videos. Hope you keep the hydroponic videos coming!
I honestly love this video and your channel! I have a quick question though if that’s cool? Should you ever leave an air pocket between the water level and the net pot in a recirculating system, and if so how much space should there be? In my system, there are multiple air stones running. However, my water levels are touching the bottom of the net pots, and I feel like I am drowning the roots or potentially going to harm the plants somehow. What should I do in your opinion with the water levels?
If transplanting a store bought plant into a kratky system (washed off the soil) how much of the root system should I submerge into the nutrient solution? All the roots? Or do I want to leave some out to breathe? (Not using an airstone)
Would love to know!
wrong,deep water means deep water
Im just learning DWC , more on this please 🌱👍
How are your hydro skills a year on?
I recently started watching your videos and love them and am learning a lot! I live in Sacramento. Thanks for sharing your knowledge!
Thanks for tuning in!
@@epicgardening Other than rooting plants in a jar of water, I haven't done any hydroponic gardening. What would you recommend for my first hydroponic gardening attempt? I need something simple and inexpensive. Thanks, Stephen
Like the video because it solves a practical problem. My current system uses overhead drip to get the roots growing, then once the roots are out of the net pot, I put water line just above the bottom of the net pot, start the water stones, then I keep overhead drip irrigation pretty much forever to replenish the water.
I know this is a 4 year old video but I have a question please. I’ve been trying to grow tomatoes in DWC. My cherry tomatoes are going gangbusters. But tried Big Boy purchased as starter plants from Lowes. Both have not been successful. The leaves curl and get spotty the flowers drop. Could the issue be I’m using small River pebbles for medium which definitely is not a wicking medium. Both already had long roots when I started that reached the nutrients and I left air space. It has been very hot days in the 90’s. Plants are outside partial sun. Thanks
Thank you so much for the in-depth answer that I was looking for white Will Smith.
LOVE your channel! I'm new to aqua/hydroponics. I couldn't get the plants that I wanted to start my 3 1/2 gal betta fish jars, so I had to buy seeds. Is this the same how-to advice for growing seeds inside of rock wool in a net pot of hydroton? Thank you for your generous sharing with us.
NOW I AM WORRIED THE MEDIUM SHOULD BE TOUCHING THE BOTTOM, YES OR NO?
Anyone seen this recently? I definitely having trouble with my first DWC from vivosun 4 pot set.
I didnt wanna soend loads on ebb n flow or any other exoensive system at least until i actually nail this qnd can get DWC right
I have only d8ne soil but the 30% plus added growth interests me the most. I've noticed a humongous diff between a soil and a dwc bucket for same exact cuts in sane exact lighting so really, i feel like if i can dial this in its easier to be honest(once u dial in whichever systen you have)
But yeah, ...so i am mostly going cheap for the exact reason as I've never done it successfully b4. (I had an ebb n flow but the guy i had set it up acter like he knew his stuff but 8n the end it was almost worthless but mostly dur to my lack of kbowledge ,kike reading a olant by seeing how wet the medium can be. Ya need that not soaked but moisr and lots of trouble getting that dialed in.
I have top drip and airstone, top drip is supposed to get it to whete the roots finally reach the bottom of the net.
NOW I AM WORRIED THE MEDIUM SHOULD BE TOUCHING THE BOTTOM, YES OR NO?
I've been researching hydroponics for the last 8 hours and I must say I am disappointed. I have watched people use toxic PVC with PVC glue (even more toxic), rockwool (which is dangerous to touch, inhale and eat), and none of the videos addresses the issue of how long the seedling net pots take to develop roots that can actually touch the water. A lot of blah blah, and never touching the key subjects. Everybody is showing how to cut holes and connect pvc pipes, as if this was the hard part. Yours is as close it got, so good job on that. But even you, you describe solutions that are unreliable, like top drip and air bubbles. Thanks thought, as I said yours is the best video on the subject anyway and your channel is very good.
I created a RDWC. But the water level is too high. Can I put clay stones under the Rockwood to create a space between the water and the bottom of the Rockwood? I am having tonns of problems...we are going through a heat wave as well....Thanks for the video!
Interesting video, good ideas shared, can you please create a Playlist of all the videos made related to Hydroponics on your channel? it would be much easier, Thanks in advance. :)
is it possible to have TO MANY bubbles which would cause overwatering with this correct placement? Would we want to lower the water level some if lots of bubbles?
Not necessarily some yes some no, Swiss chard no, it’s better to use a deeper netcup, and most of it needs to be submerged. But with kale yes you can having spacing👍
To answer your question. I am only interested in vegetables in any form....I would appreciate a title to each video which indicates accurately the subject. House plants, flowers are of no interest to me and I do not want to waste time on videos that are no good to me..But I am all ears for veg...thanks
I try to cover a large range on the channel, so if you ever see a houseplant video that you're not into, feel free to skip!
Thanks. This is the closest I have to an answer. I have CCH2O netpots with a raised "planting deck" in the middle.
Why not just fill the mason jar up to the base of the rock wool? The wicking action would keep the entire cube moist enough. Relying on an air stone would require the set up to be near an electrical outlet.
Could you leave the clonees in there for a significant amount of time before transplanting them just in case you don't have room to put them right now or I'm trying to keep them safe until I transplant them after our last freeze that usually comes 3 weeks ish into April?
This video was great, I finally realised what I was doing wrong with my last grow. Thank you!
Glad to hear!
It's more like where should the water level b? You can't move the net pot, but you can adjust water level.
lower the volume on the music please - loud music is making it hard to hear you and I have to raise the volume. thank you
This is great because I am getting ready to propagate my girls. I was looking for the easiest & cheapest way to do so.
what if all i have are leca balls and my roots are not showing at the bottom of the mesh pot yet? also, what if it's a plant that has matured in leca but now i have to repot (again, in leca)?
Great channel. Tons of info. Let me ask, how do you use strawberry bare root in a air stone auroponics?
My tap root has finally reached the water. Should i wait for a few more before lowering the water level?
Will it help if you dropped the level of the nutrients solution after roots have taken to give more oxygen to roots just a thought
Hi😊... When do you change your water once a week or.... When help
Thank you for the information sir.
can i use a peat pellet to grow my tomato from seed hydroponically?
You do go on and on, please get to the point and deliberate consideration after.
You can use the wickey way for watering. Plus you should of stated that the jar needed blacked out.
+Mark Neff yeah, that will work. I didn't mention it because it needed to be clear for the video, and the video wasn't about how to run a kratky system! But you're right, blocking it out will reduce algae growth
What size net pot should I use for a 64 ounce jar?
Great video! Thank you very much for the info
Thank you. This is very important. 👍
Thank you for your videos. I have just 2 questions that I can’t seem to find an answer to anywhere. When growing herbs in mason jar, how often do we have to change water? Or can we just keep re-watering from the top and just add the nutrients? Thank you in advance.
Oh, can you grow roses this way?
Won’t the bubbles from the air stone also over feed and drown the plant with them constantly hitting the bottom of the rock wool cube? How deep in the net pot should you put a rockwool cube? The bottom of the rock wool cube halfway in the net pot?
Glenn S thanks bro
Very helpful in many ways thanks
Thank you for sharing this video
Yeah answer I've been searching right there
What size nets are he using?
Do u flush yer veggies before u eat them
Can you do this with tree cuttings?
Its not even DWC - Itøs Kratky
Great video 👍🏾
Where does a person find an air stone?
THANK YOU!! LIKED AND SUB!
Hi! Im really glad I found you....im new to hydroponics...trying the Kratky canning jar method for herbs, greens and hopefully small cukes strawberries too..My jars are covered with paper, I have 6 jars planted...the seeds have popped but immediately became leggy... My question is without needing a degree in math or purchasing measuring instruments..what is an EZ way to determine how long to leave the grow lite on an how close should it be to the plant? I have a 12x12 in led (red/blue) combo led light...thanks so much for answering your peeps posts...no one around here is into hydroponics...so having to rely on youtube for my info. (don't use F-book)
When changing nutrients on a DWC setup, do you refill the container back to the top of the net cup or back to the level it was at before changing the nutrients? Plants have roots
Where do you get the air stone?
I’m getting ready to experiment with growing a small mandarin tree in a hydroponic DWC bucket. Very new to it. Can you do a video or at least provide some information on growing citrus trees in hydroponics? Always enjoy your videos. Thanks
my leaves are droopy and i couldnt figure out if i was overwatering or underwatering, i placed them right where you showed. I tried letting them dry out and also tried cranking that airstone all the way up. very slow growth for a week, still on first set of leaves out of seed...should i add nutes yet or hold off. i think i moved them to the dwc system to soon out of the germination pod, i saw a tiny root like yours and said! and moved over to clay and netipot. from netipot to water level it was a good 3 inches (eventually made it down there) (is that why its growing slow, or lack of nutes)
Thanks for clearing that up for me ,I'm starting my first dwc very soon,I also like your light for seedlings/cuttings just wondering ware I can get one,,
Great Content❤
Thank you, for your advice, I am just starting up my hydroponic project and sometimes do have quite a few questions. Thanks again.
In short
With roots - no worries, as long as the roots hit the water solution
Without roots - 1. Make sure that medium is moist enough until the roots start popping 2. If you have air stone, the moist from bubbles will keep the medium moist until roots start poppin. Thanks👍
You replied a question I had for so long, reason why I didn't go ahead and start my DWC until now.. I'm sure what to do, thanks for the video!
I have several 27 gallon totes running the kratky system. I drop my net pots in the top of the tote and fill the tote with water and liquid nutrients until the level reaches the first horizontal rib in the net pots(perhaps a half inch or less). For rock wool I place the cube on the bottom of the net pot and add clay pellets, for bare root plants I hold the plant up with the longest root just touching the bottom of the net pot and carefully fill the pot with clay pellets. Most plants will put roots into the reservoir in days after hitting the nutrient solution. I checked some bare root lettuce plants that I put into the tote five days ago and the roots are all over the outside of the net pot already. Peppers and tomatoes are already showing good growth.
THANKS FOR GREAT INFO
Can we use coco peat?
I've just watched the video and am using the air stones. It appears I'm doing the same as the video; the net pot has the rock wool which has the seed. The bottom of the pots are not in the water (they are actually about 4 inches above the water line), but are being hit by the air bubbles.
However, three of the pots never sprouted and the rock wool has been drenched by the air bubbles to the point of being soaking wet.
My question is can the rock wool be too wet? If so, would it be smart to only have the very base of the pot just 'peeking' through the cut hole at the bottom rather than sitting on its lip (the way you showed yours)?
did you figure it out? mine are in soil plugs and seem to be not having it, one seems amazing but still slow, im about to move them to their own buckets but they are so tiny :\
@@Hedgehodge- no I never did. I decided the rock wool just stayed to saturated, no matter what. I decided to put my seeds in seed starter plugs, took a styrofoam 2" sheet, put felt on it, and put it in a tray of water only up to the bottom of the felt. I put the seed in it's plug in a net pot on the felt, covered it with a mini green house cover (plastic with vents) - put the whole thing on a heating mat and it worked beautifully. Then once they got their first true leaves, I transferred them over to the water culture before the roots could grow into the felt. It might not have been the way to do it, but it worked for me.
@@itsasfoury thanks. Yeah I think I moved my seedlings over to fast to netpot but I'm reading a drip system helps close the gap a week or two between when roots are making way down to water ... I was googling why my plants seem sad and haven't progressed in a week, guess that's why
I imagina a piece of string from the rockwool down to the reservoir as an actual wick might work as well if you want to just set a kratky and not keep track of the moisture levels.
Too much work. Follow Kratky, submerge the lower part and forget. One time work.
Kratky is definitely an alternative
dusty rhodes should the water be below my net pods some or just to where the bubbles are hitting the bottom I can't tell how much water is in there I have a DWC 9 hole system but can't see in to tell but they are usually soaked on the bottom I've been lowering water levels but still dont know. First time with dwc any info will help
What can you teach us about aquiponics? Question from Daniel Ay @Spinning__my_wheels
what nutrients solution do you favor personally??
My go-to have always been General Hydroponics 3 part
Where do I get a "air stone" that fits in a Mason jar?
You can get tiny little ones at an aquarium store or online
I've tried and failed enough times to really appreciate this tip.
will the Mason jar being clear not cause it to get algae
It will, usually I cover with something opaque but left clear to show the height
Hi thank you for sharing. I use clear 9 oz plastic cub cover the small plant when they don’t have the roots out to the water to prevent from cold and keep it moisture. I try to grow Thai basil but the leafs getting small than I grow in the soil. But the bell pepper the leafs is so big. Do I have to increase the nutrition when the plant getting bigger or not? Thx
+rockin roadways it's hard to say if nutrition is your problem in this situation, because there are so many variables. What I would do is make sure and test your nutrient solution to see if you have enough of the macro-nutrients that basil needs: nitrogen, phosphorus, potassium. If the leaves aren't big, one of the major problems could be a lack of nitrogen
You never said how far should the net be from solution 1 inch, 2 or what
About time... this is the only video or info I've found on this subject. Homerun bro. Respect.
Glad it was helpful!
If I were to use the drip system till my roots get to the water do I drip just water or water w/ nutrient? Also, do I just check that the cube is wet daily? Or is a constant drip needed? Thank you.
Doesn't need to be super wet, just moist enough
@@epicgardening Right. Like menopause. :)
Thank you!!!
I'm mostly interested in hydroponics. I just love the life of plants, seeds to produce!! Also interested in companion gardening even in hydroponics. Love watching your informative videos.
That was helpful thanks
Thanks for video ...where you germinate the seed?
couldn't it be like, barely touching the bottom of the rockwool? that way it would be always moist and as soon as the roots popped off they'd start taking down the level of the water
Yea what your'e talking about there is the Kratky method!
Can you do a video with a variegated Monstera plant semi-hydroponic? Thanks!
Eatible plants & house plants please. I have raised beds & want to get the best & most possible! Love your channel & thanks for asking!
Great video, with quality information.
I'd love to hear about anything I can grow indoors (can't garden outside anymore due to disability). Thanks for a great channel!
PS. When you mentioned perhaps going up to three videos a week my personal choice would be for two a week - it's not too infrequent or too intense.
Thanks for the feedback! As far as plants that you can grow indoors, microgreens are a fantastic thing to start with if you are disabled because they require almost no care and take up almost no space. I have a lot of videos on it check it out
How often do you change the water for dwc? Thanks!
Problems with fixing root rot in hyperponics
Hi Kevin, You have excellent videos and great content. Keep it up!
Once the roots grow beyond the basket does the entire root system need to be submerged or just a part of the roots? Also in a deep water system in buckets how do you know what the water mix level is and when to add nutrients?
Bobby Quick I have the same question. I hope someone answers.
Is it bad if the water level is just touching the bottom of the net pot for the first few days before the plant breaks out of the medium?
Should be just fine
I would like to know more on hydroponics, aeroponics, and any gardening techniques that work for growing food crops in the high desert of Southern California. Not only is it hot and dry in the summer and cold in the winter, but the soil here is also horrible and takes a lot of amending. I would like to give hydroponics a try.
Perfect, that's my bread and butter. I can work more hydro content in
Airstone will bubble up water by it self or it has to bee hooked up with a pump?
Airstones must be connected to an air pump!
🧡🧡🧡🧡
Happy I found your channel! It's 2019 and I have been 'absorbing' LOL all the info I can on the topic of Hydroponics over the past month or so :) We Still live in the city, for about another year, and then we will be moving to the country where i can get my hands in the soil again!! Until then, and with Michigan Winters, LOL, I am learning and gathering my supplies for building my own tent system for tall plants and Mason jar for my herbs. I am also want to learn How to make cuttings from some of my houseplants, eventually :) Going to browse your channel now! Have a Great Weekend!!
Welcome to the channel Tari! Appreciate you :)
Okay my vote. I don't see enough videos on small indoor setups of Kratky hydroponics for people who have a few shelving systems and want to grow most of their produce with T5 and/or CFL mixed wavelengths. Rather than using monster sized buckets and containers, I'd rather do 1-4 quart individual containers to maximize successive plantings of lettuce, greens, tomatoes, eggplant, peppers, microgreens and baby leaf. Thanks. You are great at these videos. My hat, if I wore one would be off to you!
Good idea, I'll give this a go around! Kratky is a very popular method it seems :)
Hey Kevin, growing herbs in that same fashion, would it also work (or be harmful) to just let the water level remain at just touching the bottom of the rockwool cube so that it always remains moist while that root system is getting established, instead of checking in with more frequency to drip some water on the cube?
Thanks bro, love your work
I'd recommend that, yeah. Then again, I typically am a bit more hands-off and dump a bunch of water into the rockwool, and then trust that the roots will make their way down to a bubbling reservoir before it dries out. But if you are running these small Krakty systems like I show in this video, then yes, definitely pour a bit of water in as it evaporates to ensure moistness.
Thanks for the kind words my friend! Let me know what types of videos you want to see in the future.
Dr kratky recommends having the solution come up to an inch above bottom of net pot. To start.
More hydroponics, please!!!!
Thanks for making this video man! 💯
You're welcome!
Hello, is there and light distance - between light plant you fellow, or is there a general rule that will cover all one type of light? Again thanks for the information.
Yup - wrote an entire article about it here: www.epicgardening.com/inverse-square-law-for-light-and-hydroponics/
I got my net pots placed, got plants growing. Do I just let the plant grow full size in that first setup? What next ?
If you're growing basil, I'd let it grow fully in this system. Of course you'd have to add nutrients!
