deep water caulter is a cool way to grow i have seem some really sweet grow opps done that way and if done the right way you can pull some weight i had a friend who was using the 13 gallon buckets and using the 4 bucket setup and he was pulling around a pound and a half off one plant witch was really cool these plants were fucking monsters from hell . i like the flow and grow buckets the most out of them cause when i first started out growing i was using flood and drain tables and growing a lot of little plants and putting as many plants as i could into a 2x4 flood table witch came out to about 10 to 15 but manly 10 cause 15 would make them to cramped up and a lot of the plants wouldnt get good lighting . Then i switched over to the flow and grow 5 gallon buckets and right off the bat had really good results with it and i only had a 8 5 gallon buckets so i whent from growing a fuck load of plants to just doing 8 bigger plants that were grown completely different from when i was using tables cause i started topping them and super croping them as well as doing a few other thing to them and i was pulling around a qp a plant witch was way better then i was doing in the tables
DWC is really cheap to set up and you can grow monster plants. If I had one light I would use a 27 gallon tough box to grow one plant in. I would use another 27 gallon tough box for a reservoir, and circulate between the two.
I am using tough boxes now and am getting 1 - 1.5 lbs per plant. I have four 1000 w lights and four plants.
