Oops. Well, live and learn. I'm afraid having the light going full power is just too much heat for my little tent, so for this summer grow, it'll have to be one or the other. Bummer. I was looking forward to having them both on during flowering.
On the other hand, this looks really good for my non-summer grows, and there's a lots more of those. Hell, if just the light can keep the tent warm enough in winter, I'll be dancing in the streets, as the tent is in my bedroom and I LOVE a cold bedroom for sleeping. Gotta look at the positive!
