How to build an easy DWC reservoir for little $ + perfect nute solution + PICS!

Hello all,

I was going to send this to a friend on this site, but then decided to post it for all to see. This is how I build my reservoirs. It's simple, fast, cheap, and very effective!!

Pics 4, 5, and 6 show what you will need. An 18 gallon bucket with lid, some 1/4" flexible tubing and airline T's, airline holders and Mesh Baskets (sorry no pic, but you know what they look like). You will also need an aquarium air pump, which I didn't take a picture of. Sorry. I suggest you buy one for a 20 gallon tank. They are $10 dollars at any PETCO or PETSMART.

1) Drill a 1/4" hole on the side of the reservoir near the top for your flexible tubing to be fed through. cut a peice of tubing about 3 feet long and feed it through the hole.

2) at the end of the tubing inside the reservoir connect an airline T

3) Cut a piece of tubing about 8 to 10 inches long. Connect this tubing in a circle to the airline T. this will make a small circle as seen in pictures 7 and 8.

4) super glue your airline holders to the inside of the reservoir. I taped mine down because I use the reservoir in my pics for mixing nutes. These airline holders are to hold your airline to the side of the reservoir where it enters, and to hold the circle of tubing you made earlier to the bottom of the reservoirs. Just like you can see in the pictures. DO NOT super glue the tubing to the holders. Situate your tubing until it sits in the reservoirs just like my pictures.

5) Pull the tubing out. You now need to drill 3 VERY small holes in the circle portion of the tubing, at equal spacings. This is where the oxygen will come out to feed your roots. I used a 1/16" drill bit for this.

6) place tubing back in to the reservoir. Connect it to the holders.

7) You now need to trace out your mesh basket on to the lid of the reservoir. Cut out the hole, and place the basket in. It should fit firmly in the hole, and not fall through, so don't cut the whole too big around... You can always cut more off later if you need to. I use hydroton rocks for my planting medium.

the last picture shows the tubing coming out of the side of the reservoir and connecting to a box. The box is there to simulate the pump, I hope you get the idea. I just let my pumps sit on top of my reservoirs. This way if the electricity went off for some unknown reason the water can't back up and ruin them!!!

There you go. Pretty simple. If you have any questions, feel free to ask. I attached a few pics of what my girls look like as well. :-)

Now about Nutrients, here is what I now do:

I use general hydroponics Micro Flora and Micro Bloom only.

I use 8ml/gal of water Micro, and 16ml/gal of water Bloom in 12 gallons of water.
Do not mix nutes together in same measuring cup. Measure them and pour them in to the water separately. If you mix them together, you can cause certain nutrients to bond together, or lock each other out and then they won't feed your plant. Not good...

I USE THIS FORMULA ALL THE WAY THROUGH. THAT MEANS DURING VEG AND FLOWERING. IT NEVER CHANGES. And it works. And it's simple. Simple is good. :-) Also, I keep my PH at 5.3 to 5.6. Never below or above (if I can help it. No one's perfect all the time, heheh). I read about all these people using all these different products, and maybe that works for them. But I see a lot of problems arise from so many different things going on too...

I give my girls a fresh batch of nutrients every 2 weeks, or if they've drank 12 gallons of fresh water. Whichever comes first. That is to say that each day I add water to my reservoirs to keep them topped off at 12 gallons. I keep track of how much I add each day and once it hits 12 gallons, I drain my reservoirs and give my plants a fresh batch of nutes. Right now my girls are drinking about 1 gallon a day, so I'm changing nutes every 12 days. That's VERY reasonable to me, and really not that much work. And not very expensive either.

I hope this helps some people out. Try it. it really is easy to build and maintain.

Good luck and happy growing!!!

So how do you water them until roots are in the water? I use the method in the link below.

There's two ways to water them. One, wait until the roots are long enough to feed through the bottom of the mesh bucket. They only need to be a few inches long. I just let my clones go until then. Or two, place them in the mesh bucket, surround with hydroton, and water them a 4 or 5 times a day until the roots reach the water. They usually get there in about 3 to 4 days...Depending on strain. But I've found it to be easiest to just let my clone's roots grow long enough to feed about 2 to 3 inches below my mesh buckets to reach the water.

I guess another thing you could do is fill the reservoir higher. say to 16 gallons. This would probably surround the bottom half of the mesh basket. Once the roots are a few inches long, switch back to 12 gallons of water.

One thing I should have mentioned: When I place new clones in to one of these reservoirs, I only use a half strength solution of Nutes. So 4ml/gal micro, and 8ml/gal bloom. When their this young you don't need to change out your nutes for 3 weeks. Then I go to full strength. No problems. :-)

I really like the idea illegal smile. And I bet it works great. But I'll stick with my system for a few reasons. One, your pumps cost $20 to $30 dollars more than mine. Two, you said you replace the air stones every grow. That's another expense. I'll never need to replace my tubing. and three, needing two reservoirs (totes as you called them) instead of one. Again, that's not cost effective. Also, it seems to me that your system takes more work. And there is also the issue you talked about where it's possible to over water in the beginning and possibly get stem-rot. That can never happen with my system. And again, it seems like a bit of a hassle having to adjust water levels up and down. With mine, 12 gallons and you're there... I'm really not trying to dis you here man. I really do think it's a killer idea for a growing system. I'm just mentioning the things that would bother me in general... As I'm sure there are plenty with my system that you don't like as well. heheh. Take it easy buddy. I wish you nothing but happy growing and huge harvests!!! :-) -Snut

Actually, its not an idea. DWC growers have been doing in this way for years. But whenever there is a new crop of consumers, they want some new technology. Which invariable is some old recycled technology. Believe me, I wouldn't do it this way if it weren't the easiest way. I adjust water and bubble level once per grow - it takes less than 5 minutes. And where I talked about stem rot? I was warning about top feeding manually or by drip. I say this for anyone else to wants to read it.

Hrm. I really like the idea of using the tubing instead of the airstones... Just seems reasonable. I think that I may try this when my plants get to the flowering chamber for the first time. Thanks a ton bud!

To the OP. You need to read a bit more to fully understand dwc. The idea is to get a lot of oxygen to the plants. 3 - 1/16" air holes in the tubing is not what you need. You want small bubbles, lots of them. The idea is to oxygenate the water being delivered to the roots. Once you get any size of root ball the method you described will result in 3 small areas of the roots receiving the oxygen. I can grow 1k worth of bud with $5 in airstones. I encourage all of you interested in doing this to do some research. Illegal Smile understands. I would draw from his idea, it will lead to better results. DO NOT SKIMP on environment for your plants.

Also, I am not trying to rip on or give the OP a hard time in any way. People can make their own decisions, given PROPER information. If you want to save a couple of bucks while saving thousands, you are entitled to that. Grow on people.

Well, research would tell you that it isn't the bubbles hitting the roots, it is the bubbling breaking the surface of the water that adds the oxygen to the water. Lots of bubbles breaking the surface, lots of oxygen.


I liked the idea of a splitter and small holes being poked into the tubing... If you do it right, you could make an air curtain out of a small amount of tubing. My vision is a tube that goes around the entire bottom of the res, and then through the middle, blanketing the entire surface of the water with bubbles.

wow.... well.. i think everyone on here is a know it all. You made a couple of good points... but reading 1000 pages on dwc doesn't get rid of the fact that he posted pics of BEAUTIFUL PLANTS that looked like he wasn't skimping his plants environment at all.... I have one question. If you have one air pump delivering air to three small holes... and then u hook that same air pump to air stones.... which one will produce more bubbles? Well seeing that there is still one air pump delivering the same amount of air to the air stones... and to the holes... which one is better? the answer is... neither. They both will give off the same amount of air because they both are recieving the same amount of air. SIMPLE LOGIC WILL SET you free from your know it all aspects.....

those 3 holes should the go around the circle in a tripod angles? and why only 3 ???????????????
Yes, at tripod like angles.

The reason I chose 3 is because if you put too many holes in to the tubing, the pump will not push enough air to get out. I experiment with 6, then 5, then 4, and decided on 3. You get good air flow, and plenty of oxygen to the roots. Also, if the roots lay on the tubing a little but, it's not a problem because there is enough air pressure to keep them off of it.

glad you like my idea! You've seen my pics, it works VERY well!!! :-)

love the way you grow... will be trying out ur methods in a dwc grow... +++++rep
I don't think you will be disappointed my friend!!

yes, airstones plug up. And though they are not expensive, I don't like having to deal with them. This works just as well, I don't care what the bubbleheads have to say about it. I've proved I can grow just as killer plants, if not more so, using my "simple" method!

Really? Well then, why are my plants doing so well? Why do i get EXPLOSIVE growth every day? I see up to 3 inches of growth a night during veg. I can guarantee you I am getting plenty of oxygen IN my water TO the roots. :-)

I will post a picture of one of my root balls. They are quite huge. I can assure you that oxygen is getting to more that just 3 small areas of the roots. I understand DWC well. My water is oxygenated just fine. If it wasn't, well it'd show in the grow...

Thanks. Couldn't have said it better myself. Glad you like my girls. And I don't even have to work that hard at making them happy. I understand what that guy was saying, but the proof is in the pudding. My plants thrive

I LOVE the idea of using tubing instead of airstone. This will save me some cash since all the airstones clog up.
Yeah, it's not a huge savings. But I'm all about saving money when I can. Did you see my other post where I built a 5 gallon DWC reservoir in less than 15 minutes for less than $15??? This may be just right for you. Here's the link:

and some new pics for the doubter on this thread! :-) I can't wait to post final pics. You'll love what you see.
