@hothrebel go with a 315 cmh, it has a great coverage for a 3x3 text. Been using one for a while to cover that size area and its great.
I actually received purchased more from cultilux and I got them for a steal, by emailing the ig rep,and they are working out great. 3 year fixture warranty and 1 year bulb. Landed, each fixture with two bulbs (3000k + 4000k, was about $230). And they are still shipping so that's nice.
I'm going to be trying both side by side in flower from clone, but I really think I like the 4000k bulb better. But it could have been the strain/pheno.
