All I can say about the cal mag is that the better the led's, the more the girls seem to want!
Thanks for the compliment about the girls, I try to knowingly torture them as little as possible
No offense taken, se450 is cool with me, I'd just not necessarily make the same choice...
If you're goin with 1 se250 are u gonna supplement the light with somethin else?
I was thinking if I went with one se450, and only six plants and needed a little extra light I could remove the lenses which would throw some more light, I just wouldn't get as much penetration.. i don't know if you can tell but I have been a little beside myself in searching which lights to buy.. ahaha! all over forums and picking a lot of growers brain's on investing in lights.
