Building a Rubbermaid Hydro Bubbler Unit - Cheap and Effective

I would grow small plant's maybe clones bud on a stick style in that system... If your gonna grow that way from seed I would suggest doing one plant per tub unless you plan to move them quickly, the roots will begin to grow together, if you have a male in the bunch removing him from the girls will cause damage to their roots, and if you cut him out and leave his rootball it will rot and cause problems to the girls in the root zone. Just my two honest Abe's...

Hey, I'm gearing up to give this a try. Thanks for the awesome info and pics. I have a question about the foam insulation sheets. I'm not exactly sure what you're talking about. Is this the stuff:

SUPER TUFF-R 1-3/8 In. 4 x 8 Polyisocyanurate Rigid Foam Insulation - 1347 at The Home Depot

Thanks again.

one quick questions regarding airstones. can roots get damaged from being to close to the air stone it self, recieving some turbulance from the air from it?

thanks for your time

Add your growing medium (I use Hydroton - expanded clay pellets) on top of the wick, holding the end while you pour in the pellets or medium. Leave enough room a the top of the net pot to place your plant into the pot, on top of the wick, and then add the remaining Hydroton to stabilize and cover the plant's root cube or rockwool.

Place your net pot in the bubbler and repeat until you have added all of your plants that you want into the net pots and bubbler. If you choose to leave some of the net pots empty, I suggest filling them with hydroton or taping them up. You do not want any light entering the reservoir or you will end up with contaminants and algae growth in your nutrient solution. I actually like to leave one or two spots open so that the plants have room to grow, and more importantly, I can remove a net pot to check pH and PPM a couple of times a day.

Well my camera battery has died, so I will continue this in the next day or two when time allows. It's almost complete so this should be enough to get ya going. If you have questions post them to the thread and I'll do my best to answer them for you. It may take me a day or two but I will reply.

Happy Hydro!

When u get to the strips is itjust one cut layer say from the back of a shirt or is it 2 like sewed so it makes like a cloth tube.

Getting started - first the parts list:

(1) 10-gallon Rubbermaid Roughneck storage bin (Lowes $5.50)
(1) ½ inch I.D. clear vinyl flexible tubing, 12� length (Lowes $0.50)
(1) ½ inch plastic elbow (90 degree) for flexible pipe (hydro store $1.50)
(1) rubber grommet for plastic elbow (hydro store $1.00)
(6) net pots of your choosing â?? I used 6â?� square pots (hydro store $1.50 each)
(1) aquarium air pump, dual output (Walmart $15.00)
(2) aquarium air stones â?? 6â?� length (Walmart $1.60 each)
(1) roll of aquarium tubing â?? 10â?? length (Walmart $2.50)
-------------------------------------------------------
approximate cost ~ $38.20


Tools needed:

Utility knife (or jigsaw if you have one handy)
Drill
¼ � drill bit
¾� drill bit

We'll get going in a minute by building the base of the bubbler.

To give you an idea of what is possible, I just completed a grow using 2 of these 6-pack units that yielded 4 oz of Black Domina in one unit (2 plants), and 3 oz of Blueberry in the other unit (3 plants) using a 400 watt HPS in a 4'x2' closet that was 6.5' tall.
