with 50-60cm plants how many can i fit in a cab thats 14x26x42inches? I can get any wattage necessary with CFLs
the area is 14x26 inches? I wouldn't try more that one plant in there, personally. You could do two, but have to do so much cropping, trimming, and tying that your yield wouldn't be any greater than with a single plant. In fact, it might be less due to crowding! Doing more than one would be a waste of time and resources IMHO.
