Just wondering...
As long as you're pushing from 420-470nm blue and 630-670nm red you're hitting the high peaks and doing fine. Given what you've said about the panel, supplement with more blue, please.

It's been a while since my last grow (mind you, the little lady and I don't consume as much as I grow) and I had a bunch of leftover Afghani Special seeds left.

Since my Grow cab is stuffed with stuff that would be all over the place, I decided to come up with a second one, a bit smaller. new grow cab - 10 Cubic feet, white finish (no need to paint natrurally Rating: 5
