I agree. Old-school methods suggest a 3x increase in light from growth to flower stage. Your 65w bulbs are what...200w equivalent, each? So it's no real increase. Flowers of any kind require shitloads of energy. Cannabis included.

Depth of usable light penetration (how far the usable light penetrates) is also a consideration. Plus, the heat the CFL's generate is held-in by the foil. Walls painted flat-white work fine.

How far from the tops are your bulbs?
