Things you need (Pictures are in order)

1. Rubbermaid Tub â?? (I use a 20 Gallon)
2. 2-3 Fish Air stones
3. Air Pump
4. Black Air Hoses â?? (the one in the pic is clear but try and get black)
5. Net Pots
6. Growing Medium
7. This is what your final product should look like.

1. What you need to do is cut holes in the lid of the Rubbermaid container to fit your net pots in.
2. Then run the air hose from the air pump into the bottom of the Rubbermaid container and plug them into the air stones.
3. To check to see if your air stones are producing enough Oxygen fill the container up with water. Then put the lid on and start the pump. Come back in a few minutes and see if water has splashed through the holes and collected water on the top of the lid.more in next post, the postman.
Hey Postman. I'm new to the forum and growing as well. I am current card holder and venturing off to grow my own. I chose to go hydro with a setup similar to yours. I am using a 20 gallon tote as a self watering setup. I got the idea off of youtube. The tote will be divided in half by a styrofoam slab cut to fit making the bottom of the tote the nutrient resevoir. Also in the nutrient resevoir is a wicking basket of sorts filled with hydroton and drilled with 1/4" holes. On top of the styrofoam is a thick layer of hyroton for my roots to grow in. I'm putting 6 3" net pots in the lid also filled with hydroton. Along the side of the tote will be a 1-1 1/2" pvc pipe for the air line to run to the air stone in the tote. This is also the watering tube. There is a drain hole consistent with the styrofoam to avoid over watering. I'm running a walmart pump suitable for 20-60 gallons with a 5" air bar. I'm not a very good artist but I sketched a pic of what I'm goin for..
Can I eliminate all the hydroton and wicking system and add more nutrient/h20 solution and let the roots hang in the solution? My tote is black, do I need to spray paint it anyway? Is Co2 a necessity?
