Hello GC, This is my first thread i'm actually looking into a box that is 72"Hx26"Wx18"D....I will be growing in hydroponics instead of aeroponics. I will be looking to have a perpetual grow cycle...the entire box will be broken down into 2 chambers...Im looking to have the top chamber about 22" for veg/clones with 3 55w CFLs and the bottom with about 46" for flower/budding with a 250w HPS....my question is do you think I will have enough room to produce a 1/2 lb per harvest? I will be using a combo of a carbon filter and ona mist for plant odor, would this be effective? Would the 250w HPS have enough light to push the HP?? As for nutrients I plan to use the basic 3 grow nutrients in addition to advanced nutrients connoisseur A&B during flowering. Any feedback will be appriciated...thanks
