Footprint of a 250w is about 2x2, 400w is 3x3, 600w is 4x4, 1000w is 5x5 (depends on the reflector you're using for these, but thereabouts)

You could mount a 250w in the middle and use some CFL's on the sides :twocents:
bigtopsfinn Reviewed by bigtopsfinn on . SCROG grow I was wondering if doing a SCROG grow. Would I be able to use a 250 watt HPS light to flower a 4x2 screen? Could I use a 150w HPS and four 48" fluoro tubes? I already have the fluorescent lighting over 6 new transplants and some clones that are rooting, and was wondering if I could utilize these?
