Hey! Just read the whole thread and was reminded of a setup I saw a few years back. Flip flop system, 3 lights (1000 watters), hung vertically, 8 plants around each one in 5 gallon bags. Rotated each day and examined as well to determine health, bugs etc. Only on the ground so it was only one level but looking down on it looked like 3 crop circles, true that the plants were rock hard all the way down and with the addition of Epson salts they stayed green all the way thru. In the end it produced almost 3 ounces a plant. 48 plants, 6 lights, 80 grams per plant, equalled 1.4 pds a light. I guess if someone had the time and space this method would be nice to have but it is alot of work, and you would have to sleep in the dining room because the veg room would be in the washroom, people love the flip flop system but again the work load is continuous, and your not gonna have much of a life until you decide to pack it in. Then again the things some people do for money! Take it easy boys, everything's lookin good.
