<sigh> Wrong. A 'shitty' strain grown under CFL's will likely still suck when grown under HID's. But it will be a fuller, larger version of suckiness.

CFL's only extend a few inches, while 400w lamps extend effective range to about two and a half to three feet. (more lumens on more leaves, means more energy available to be stored and used by the plants)

It's akin to the difference between a plant grown in the shade versus a plant grown in full sunlight. Although they both can flower, the one with the least light struggles, in comparison.

Using CFL's...you need more patience, lol. :jointsmile:
