Yeah what THG said, andas well keep your plant numbers low, IMO less pots=less oil, water and nutes.. which means less $$$ per gram. I can comfortably put 4 plants in my tent and have plenty of room to work with the plants and allow sufficient air flow, and light to penetrate to the lower buds. I have recently been scrogging 2 planys and creating a nice full canopy and trimming anything underneath as it really gets no light down there and just staels energy and nutes from the colas. I end up with approximately 8 ounces off of that method and keeps my cost low. The downside is I have to veg a little longer to train my plants and fill the trellis netting. Hope this helps.
