My bad stinky, I should have elaborated a bit...:jointsmile: Its going to be in a space thats 40"L x 20"W x 56"H. Yeah keeko but was actually thinking about two of them using the 5000K for veg and then change them to the 2700 for flowering. I was thinking using two 105w for veg and then go with 2 125w or even the 200s for flowering. Anybody?
