khyberkitsune, I've found LED lights to be greatly under-powered for Cannibus flowering. Can you give us your thoughts on this subject and what might be new and improved!
24" tall in two months is done under CFL fairly regularly, both from clone and from seed.

LED being under-powered? Only partially true. The biggest failure of LED panels is wasting energy in the least efficient wavelengths (eleven bands is a total waste when there's only 4 main photosynthetic peaks) and then they are usually made in the most improper ratios of red and blue.

I've got nice hard buds growing under LEDs and a fairly bare minimum of nutes. No wispy stuff here until you get closer to the bottom of the plants. Some colas are as big around as my D-cell flashlight. What used to smell like black pepper now has a much sweeter smell, and the buds on touch alone are extremely sticky.

And the amount of trichomes produced are lovely.
