Where Should You Place Your Net Pots in a Deep Water Culture System? 

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.

Thank you!!! This is the question I always have after watching so many hydroponic videos. Hope you keep the hydroponic videos coming!

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.

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'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.

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 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,,

Very helpful in many ways thanks

Hi Kevin, You have excellent videos and great content. Keep it up!

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!!

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.

Thank you, for your advice, I am just starting up my hydroponic project and sometimes do have quite a few questions. Thanks again.

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

Hi Kev, I found your channel while searching for hydroponics / DWC as I am new to this, I have gardened for many years ( I'm 56) and I love all aspects outdoor, indoor hydro, DWC. Im happy to watch and learn whatever you have. I would recommend that you make your videos about whatever you are doing at the time. Really enjoy your presentations and appreciate your efforts 👍

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

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?

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)

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!

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)

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

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?

Im just learning DWC , more on this please 🌱👍

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)?

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

Thanks for video ...where you germinate the seed?

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!

Hi Great video, I am growing in dwc for the first time, I am using water from mIy tap that is treated with chloramine, the plant seems fine for now but worried as I have read I should use a R.O filter but I dont have space for one at the moment. Do you know how bad chloramine is for plants in hydro?

Great channel. Tons of info. Let me ask, how do you use strawberry bare root in a air stone auroponics?

Thanks. This is the closest I have to an answer. I have CCH2O netpots with a raised "planting deck" in the middle.

How often do you change the water for dwc? Thanks!

I recently started watching your videos and love them and am learning a lot! I live in Sacramento. Thanks for sharing your knowledge!

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 very important. 👍

Hey Kevin...pretty epic channel you have going and it's super helpful, especially for someone in India where the learning tools for hydroponics are limited....had a couple of quick questions....for germination, would it be correct to keep the water level at around 5-10% above the base of the net pot....second, what would you say is the perfect germination/growth medium for a hands-off setup....I'm thinking base of rock wool topped up with coconut coir with a bit of vermiculite thrown in...works?..thank you!

Very helpful, thank you! Bout to start my deep water culture under fluence bioengineering led light. I'm pumped!

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?

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.

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!

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

That was helpful thanks

What size net pot should I use for a 64 ounce jar?

can i use a peat pellet to grow my tomato from seed hydroponically?

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

Eatible plants & house plants please. I have raised beds & want to get the best & most possible! Love your channel & thanks for asking!

You're the best!!!! Thanks for all your help.

House plants AND Hydroponics! I'm working on incorporating hydroponics with my house plants in an aesthetically pleasing way in the apartment.

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)

Can you do a video with a variegated Monstera plant semi-hydroponic? Thanks!

I got my net pots placed, got plants growing. Do I just let the plant grow full size in that first setup? What next ?

Hi😊... When do you change your water once a week or.... When help

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.

Great video! Thank you very much for the info

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)?

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.

Can we use coco peat?

Where do you get the air stone?

About time... this is the only video or info I've found on this subject. Homerun bro. Respect.

THANKS FOR GREAT INFO

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.

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.

Great information! I like edibles and house plants! I want the inside of my home a mini jungle lol 😊

This video was great, I finally realised what I was doing wrong with my last grow. Thank you!

Great video! Really helpful information!

Can you do this with tree cuttings?

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?

Thank you for the information sir.

Great video. Very informative. Thank you.

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.

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. :)

You can use the wickey way for watering. Plus you should of stated that the jar needed blacked out.

Great video mate! Answered my concerns straight up!

What size nets are he using?

Yes on all of those ☺!!

Awesome man...i've been researching this and after a bunch of videos you have the best explanation

Thank you!!!

thanks for clearing this up as a newbie there are so many variables to figure out :) If I was to go for this in a dutch bucket and use the drip method to start, how do I know what drip-rate is "right"?

Airstone will bubble up water by it self or it has to bee hooked up with a pump?

Starting Chilli plants for new Growers

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?

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?

Good info, thanks for sharing. All the best..Peter.

Great video, with quality information.

Thanks for making this video man! 💯

Love this. Learning tons. How about working with small spaces indoors like with walls, shelving, etc?

what nutrients solution do you favor personally??

Great video 👍🏾

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

Where does a person find an air stone?

Ive been a garden lover ever since i was a kid growing with my grandparents every summer.....my thumb is mad green!! Its nice have someone my age with the same passion. Cannabis is now legal in Canada, 2020 being our first legal outdoor grow season. Id really like to see you do videos on the topic.....indoor..outdoor. soil hydro stress training nutrients.... the list goes on.... Plz plz plz 🍒cheers mate

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 never said how far should the net be from solution 1 inch, 2 or what

Do u flush yer veggies before u eat them

How do I tell how far below the water goes if I can't see into my system ?

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?

My tap root has finally reached the water. Should i wait for a few more before lowering the water level?

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.

Yeah answer I've been searching right there

What is rockwool, and where can I get it?....same goes for the "airstone:.

It's more like where should the water level b? You can't move the net pot, but you can adjust water level.

Thank you for sharing this video
