If you lights are in the growth spectrum for our favs, it's gonna grow....but you got to remember the InverserSquare Law, the farther away, the more dimished quality.

I have been using in a pair of small boxes, small lights, Box A, is 2-150hps and a 70mh,that box I usually get packed in jars, 130-150 grams of bud, dried with a 3 week cure.
In Box B, I use a 1- 150hps, and 1- 70 mh, and that box generates 75grams to 120 grams of dried paked away bud, and of course a 3 week cure.
I just hate weed thats not cured and never smoke it, I prefer nothing to nasty uncured weed.

Anyway in my 6 years of running these boxes, I find it's more about *how close you can get you bulbs to the plant*!! Burning stunts growth, so I dont want burnt tops...but I want them as close as possible. I also move my bulbs around to get more decent bud than popcorn.

I'll try and post up a pic or 2, if it dont work, well I'm old and suck using a computer...but I'm still trying.
