I would say the more the better to a certain point, I would say that three in a space like mine would be ideal. they claim around 10000 lumens a piece but I have seen similar lights only say around 8-8500 But then you have to think about heat issues too because they do throw off quite a bit of heat. Yeah that is exactly what i did. I had them mounted to a movable board that i just raised up as they grew. :jointsmile:
