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 ?? I used 6? square pots (hydro store $1.50 each)
(1) aquarium air pump, dual output (Walmart $15.00)
(2) aquarium air stones ?? 6? length (Walmart $1.60 each)
(1) roll of aquarium tubing ?? 10?? 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.
Fantastic instructions

The instructions i used personally are here -> clickey!
