@Four20, Just one, It seems to be pretty good. I'm thinking of putting it in a smaller tent for seedlings, clones, other projects and bumping up on a LED in the med tent. Next Time, I'll put the autos under the LED and the Photo under the 315w. I love my 315w but I'm learning that LED's are pretty awesome.
@Four20, Thanks, Ive been playing it pretty safe and things seem to be going well. Ive ventured out a little with defoliating but I didn't want to be too aggressive. Im amazed at how resilient they are.
