Any sugestions, any preferences? Going to head on out tho the hydro store next week and buy some new lighting. Going with 2 x 1000w hps/mh, but am unsure as to what type of reflector/hood to get. The ones i currently use are gull wing ones that i made years ago. I was looking at maybe a cool tube but the design looks as though its light foot print would be small. Anyone ever use one of these?How much heat can i expect it to disperse?
