Even with cfls or t5's your still left with a 2-2.5 ft plant. Even If you trained it to take up all the useable space 2x2x2.5 your gonna end up with a very small amount of end product. You would have to veg damn near 2 months and lst and supercrop the hell out of it. Then 60-70 days flower time to yield 14-28 grams isnt worth the electric. That only my opinion tho
