Im constructing a grow box that is going to be 4x4x6 or maybe 7 but the question i keep coming too is the lighting and whether i should use a 600 or a 1000. Ive read for the 600 you loose 10% yield but at a gain of 40 less power consumed. I have a good amount of 1000 bulbs and ballasts around and a 400 MH and HPS. Should i use the 1000 watt and the older ballast or maybe buy a nicer digital Rating: 5
