- Had some fairly nice boards left over from the deck and I've been thinking about standardizing how I grow things n the greenhouse, so I came up with this solution. Not a lot of expense involved, but a whole lot of labor to make it happen. I really enjoyed this build!

New subscriber and soon-to-be hydroponic enthusiast here from the Philippines. Thanks for your video.
Thanks and welcome SF.
You're a fine craftsman Brent. I can't wait to see it in action!
Thanks Jim!
Thanks you very much sir for your video, my husband, is also trying this method of hydroponics so that it can helps in our daily life..
All the best!
Amazing DFT setup
Thanks!
Those are really nice looking set ups. I have no doubt you will fill both of them with the best and healthy looking greens and everything else you decided to plant on them. Will be on the look out for the videos. Best wishes Mr. Brent and TFS.
I'm optomistic. We will see and I'll share. : O)
Looking really good Brent. I better get going on mine. I don"t have the flooding to worry about that you have there. Wow I guess I can be grateful for that. I am going to be doing something quite similar to yours but I will be using fish water and I am thinking of using a combination floating raft and a fill and drain with a suspended raft. Whatever you would call that...I don't know. Good luck, hope you get way too many veggies to handle.
Ed
You sure can be greatful Eddy. It sucks when it happens. Thank goodness it's not unbearably often. I'll be watching your progress Eddy. Take care brother.
Looks like a great set-up to me. Best wishes Bob.

I'd say it's a self replenishing Kratky bed, with air stones. I wouldn't waste my time with the air stones, since it will be suspended above the nutrient mix anyway. the plants will get plenty of oxygen, as long as the net cup is no more than 1/4" into the water. I think you will like it! You've seen what I have done with Kratky. I don't know of anything that I have not been able to grow in that system, and it's soooo easy! The nice thing about the recirculation is that you can continually change out plants after a harvest, and don't have to worry about stagnation, or cleaning in between, vs the way I do it. Just grab out the extra roots, and keep on truckin!
Exactly my thoughts Keith! Appreciate the inputs buddy.
The OSB didn't work out well for me Brent. The humidity in the greenhouse caused it to delaminate. It began to break down after 2 or 3 months. I changed over to #2 plywood and so far it is doing pretty good.
Looks like I'm doomed to the same fate then brother. Darn the luck. Guess I could try and paint it.
That's a good idea. Wish I'd thought of that!
Chuck
Very nice build Brent! I especially like the re-circulating aspect. Look forward to the grow vids.
I'm looking forward to it myself. Never done it quite this way.
The floating raft was my first take-off point for hanging root pouches. There are so many variations for hydroponics and imho, there is no wrong way to try something new. I think the first objective is to grow tasty stuff. The second objective is to share experiences. The third objective is build on the shoulders of those that share and then re-share. Thank you Brent.
Notable objectives!
Nice build Brett - Cheers!!
Thanks Jim. Now, let's see if concept = production! Glad you stopped by sir!
Nice build, I think it will work fine, my only concern is the support for the polystyrene, when you get some of the heavier veg in there. I think you might have to tweek your support system, there is going to be a lot of weight in the middle. I guess that is an advantage of the raft style, the water is the support but even that system needs the same size plants, of the same weight, to keep the raft level. I look forward to following the progress. Great job Brent.
All part of the learning experience. Like you said, though, it can be tweaked later if needed!
I am lost seeing this video..it is because I am not a builder..LOL..it look too perfect!
It was fun to build.
you are going to be one salad eatin' fool!!! lol...love the setup..just wish I had room for that much!! Maybe I can add onto the back porch (and have less back yard to mow!) looking forward to updates on this "hybrid" system..good luck!
Damn son, I thought you were gone! Where's the vids? Not much of a regular salad eater actually. Two or three a week. Enjoy plain lettuce, tomato, and cucumber salads. I've supported it so well because I want to grow more cabbage, broccoli, celery, and other stuff like that.
vids are fixing to start again...work keeps getting in the way...we are just now getting Christmas lights out of the front yard! Time to switch from "Christmas light mode" to "Gardening mode" :)
Lol. Good to hear you're coming back.
So do you have any updated pics to share of how it grew? Nice video
I'm sure there are several in "Greenhouse Updates" for that year. My channel introduction has me sitting on the beds with tons of big stuff growing in them.
Going to look for it now. Any regrets of the way you built it? Too shallow? Im wanting to go that shallow also due to water shortage at my well. I’m building mine tomorrow on your design so I hope you can get back to me soon. Any chance we could talk on the phone? I’m going on pretty big scale 30/40 ft greenhouse.
No can find but will keep looking.
@@larrymarcum1673 The depth I used was based off of deck boards and it worked very well. I'd keep the depth. The plastic could use an upgrade to maybe a pond liner or perhaps greenhouse 6 mil. You can email me for back and forth: c3voyage@gmail.com
really helpful!
I'm glad!
I do believe my old water bed frames might work for frames. could i use a rubber roofing membrane for liner? very meticilous instruction. thank you
Thank you JM! I'll look for your project.
Coming in late by a good number of years my question is the foam that you’re using to put the net pads nut cups in is that food rated because there are some forms and products that one put in water can leach out the chemicals within the phone causing poisonous chemicals in the water as well as your plants would absorb as well could you let me and others know unless somebody’s already asked the same question greatly appreciate it thank you
From my book 4 years ago:
Toxicity occurs in everything, everywhere, and in differing degrees. For simplicity, let’s call it all “harmfuls” regardless of how much they can actually harm us. Harmfuls can be plastics, metals, foams, liquids, or any interaction of any of them with anything else creating a gas or by-product. My list of harmfuls is understated to say the least. I believe each individual has the right, and responsibility, to learn all they can on factors affecting them and their family. I certainly am no expert in any sense whatsoever. If you’re subscribed to me on RUclips, and watch just one or two of my videos, you know. :O) I think we all do a pretty darn good job with questionable issues and filtering out the unimportant stuff. In our filtering, we each come to our own conclusions, thoughts, and opinions on the impact of harmfuls, and what we’re willing to live with or what we cannot live with. We further grow those thoughts or opinions as life goes on. We know we live globally-saturated with perceived and actual harmfuls. Most harmfuls have had phenomenal plusses for society and yet they’re still a huge issue for our planet’s health and future as they eventually become a waste. Where do we draw the line? Really, about all you can do is draw your own lines. I’m in the middle with how I regard harmfuls, but I certainly understand and respect how each individual feels on the subject. I know I will likely reference something in the book you feel is not for you and I’ll likely offend someone, somehow, but I honestly cannot do what I do, share what I share, or write what I write, without harmfuls in some form. If you take offense, please use the offensive part as a guide to try something else. I’m sorry, no refunds. :O)
I want to be serious, for a second here, and I cannot stress this enough: I cannot take your personal responsibility away from you. You should never surrender it and you must always do your own due diligence before making decisions. I’m not being nasty. It’s such a gift and a wonderful part of having freedoms. Let me share a little on some of what I’m talking about concerning harmfuls so you can consider how you feel about it and make adjustments as you see fit.
Plastics & Foams. The toxicity of plastic, especially with leaching, is one of the most common comment-related concerns on my RUclips channel. The type of plastic, what chemicals make up the plastic, how the plastic is fabricated, leaching of plastic, how temperatures affect plastic, and the deterioration of plastic is a small fraction of concerns related to plastics and foams. I try and use what is considered food-grade, non-hazardous, or health-certified options, from a reputable source, where I can. But, after research, I still use, and am ok with some controversial plastics like PVC. I think of foams similar to plastics. They’re probably manufactured from many of the same chemicals and I’m not smart enough to know the difference. I do know the Dow foam, I use, is labeled as “non hazardous”. If you dabble even a little bit in hydroponics, you’ll see all manner of foam and plastic-related uses. In fact, it’s everywhere, not just in hydroponics. Find your plastic happy place.
Plant Absorption. On the subject of micros and harmfuls, it is certainly worth talking about plant reactions to harmfuls because they’re what you’re eating. I mean, most of you likely don’t care if you touch plastic or foam, but do likely care if you ingest harmfuls absorbed by your plants. I’ve done research into plant absorption of various harmfuls. I suggest you do it as well. Plants have a great ability to filter out most harmfuls. In fact, plants use and need elements like metals and even chemicals like chlorine. Did you know that? And, so do we. I believe choosing the safest harmfuls, coupled with a plant’s ability to filter them out, is a great combination to assure us. Ultimately, you do you! Research and find your plant-absorption happy place.
You are so beautiful...to me! Ha, Hi Brent. Another fantastic video!!! 3" net cups? And you happened to find craft sponges that fit the cups exactly? Dude, you rock! And craft sponges...brilliant! Love love love the set up. May I suggest a cube shape for the center support, so it wont fall over. I just started some seeds here in Colo. yesterday. Snow Peas, Jalapeños, Cucumbers (sml bush) and a boat load of lettuce. And 72 flowers, 4 kinds. I have two trays sitting outside inside of two 3' (under bed storage kind)making a make shift greenhouse (tiny space style). Then I'm going to use those 3' containers for "Self watering pop bottle grow boxes" for my lettuce. Waiting for my ship to come in. So let me know if you see it floating around in your "Summer Greenhouse". :)
It is hard to pass a mirror! : O) Yes, 3" net cups. It's what I started with a long time ago and I have so many and the hole saw. Otherwise, I might do 2" cups. I think I will do a more robust center support in the future. I just didn't have the extra PVC pieces for it at build time. Great advice. With your setup, sounds like you need to break out the video camera and get to tubin'. All the best.
very nice video! just wondering is there no nutrient reservoir? if there is not, does the drained water goes directly back into the growing beds and it keeps circulating? Do you use water pumps to keep the water circulating? If you do do you keep the pumps on the whole time? And do you ever completely change the water every so often? Also noticed your net pots were quite far apart, what did you end up growing?
Yes, there is a reservoir it drains too which was automatically adjusted for ppm by concentrated nutes and topped with gravity fed water. Water pumps on a timer were used. During that period, I didn't change out the nutrient. Only topped up. Now, in my grow tubes, I may change it once every month or two. In this setup, I mostly grew broccoli and cabbage and the net pot distance was appreciated.
There are videos of plants growing in the beds too. Even my page intro video shows the plants.
Nice build Brent. How long did it take you? I'm gonna guess, weekend?
Can't wait to see plants grow
Paul
I tend to have a bunch of projects going on at the same time. This build took like a week or a bit longer. I'd work for an hour or two, then some days nothing, then much of the last day before publishing the video. I believe it can be easily done in a weekend.
Nice system. But, I would like some info on your strawberry plants. How do you revive them from the fridge?
Some thoughts on strawberry plants. I've had the overwinter fridge success with the variety "Chandler." I've not been able to revive them longer than 2.5 months and that longer period I attempted with "Ozark Beauty" so it might be the variety or it might be the length of time. I could probably figure it out if I put my mind to it. If you put in crisper, keep right at freezing, say 32 to 40F as a guess and keep moist. Keep an amount of ever slight nutrient value water in the crisper so it's the same temp. Use this water to rinse and re-wet the strawberry plants once a week or more. All I did was pour a cup in the strawberry containers and shake slightly to coat everything and re-wet. This removes older, nasty water, and refreshes and moistens all the plants. Empty water that collects on the bottom of the container. Sounds like a pain, but it is really super simple. Once you put the plants in soil and a warmer environment, they react and start growing. Hope that helps.
Hey Brent. Nice build! I will attempt to do a RDWC one day as well....curious since you did not sit the foam on the water, did the air pocket affect the temperature of the water or any algae growth from the bottom side of the foam from potential evaporation? How's the condition of the bottomside of the foam after a few months, and any mold? Appreciate your feedback experience.
These no longer exist so there's that. That greenhouse was removed. For the time it was up, there were no issues. No algae and bottom of foam was pristine.
Use 1/2 inch or 1/4 soaker hose you hook it up tomyour air and it bubbles out it use washer to weight it down then you can make custom size air stones
Lots of options isn't there? :O)
How big should the nutrient reservoir be in comparison to the size of the beds?
Same size as bed; to the top.
Seems like a recirculating Dwc setup
Yes, sort of. DWC is a form of water culture that's not really defined as to what is "deep." In the older days, it was called water culture or solution culture regardless of depth. It doesn't matter really what someone calls in my book.
here is a tip, if you use a magnetic drive guide, you may already have one. they have different lengths. you put the right torx bit in it, then the screw, then slide the metal guide out to just when the tip of the screw points out. this will hold the screw inplace while you screw the deck screws into the wood. no pre-drill is needed.

Thanks! Going to order one.
You just can't help yourself. Just like me you watch too many videos. I'd say you have a DWC but airstones are a good idea since there won't be that much air space between the water and foam. As for the center support running PVC down the center with 4 legs and attach it at each end would probably have been sufficient. I believe hydropnic growing whether raft, NFT, FAWN, or dutch buckets is a more controllable way to go because there's less guesswork in the available nutrients. Your videos are always interesting.
Thanks Jeff! Wise thoughts you got there.
One more thought. Do you have a bottom drain for totally draining the bed?
You bet. The return line isn't glued. Pops right off and will let me drain it. That was part of the design.
