some thing as simple as these system that they sell you for $100 + dollars is outrageous!!! you can pick up all this material for about $25 at any store like wall mart or major home store.

plastic tote $ 5.00
dual diaphragm air pump $ 10.00
air stones -qty 2 $5 for both
net pots any size you want anywhere from 50 cents up to $2.00 a piece for the larger 6" ones you will have to go to a hydro store to pick these up.
the only thing left if your choice of nutrients.


the only thing they do for you is cut the holes out in the lid, if you have a whole saw or a razor knife just flip your net pot up side down mark it with a sharpie and cut. about 10 min in the store and 10 min assembly time just saved you $ 50 bucks.
