Ryan, I'm happy with the growth and especially the color. It was a little browned out when I got it. It's a really nice blue/purple now. I wasn't thrilled with it when I got it, but it's looking way better now....almost makes me think it is worth the price. ;)
Where do you have yours? Mine is in mod flow and about 3/4 down directly under a MH bulb. I would say under around 275 PAR.
