Maybe I can give you some helpfull advice as I have seen what a person can do with DWC. What I like to do is have a bit bigger plants in DWC buckets and set it up like a perpetual harbvest.

You can go 4 rows of 4 or 5 rows of 5 with small plants , so thats like 16-20 plants in a square. But thats alot of air pumps!!

You shold go with 3x3 under a 600 watt hps so thats 9 plants. You might be able to yield 1-2 oz per plant.
cheesypeace Reviewed by cheesypeace on . DWCSOG DWCSOG... I posted this theory on another forum a while back. Thanks to Penguin and Don from GardensCure...Been really busy moving an sh*t. But I'm settled in now and ready to give it a crack. Got my research notes and am ready to go. I initially wanted to utilize the explosive growth rates of DWC and the high plant numbers/high bud density of SOG. They showed me that using a 3foot x 3foot x 1foot tall container would restrict the roots growing if I were to allow 2 weeks veg - 49 plants BTW. Rating: 5
