Light height

iv got 9 cxb3590 at 40w each and 4 Samsung boards at 140 between 4 how high should I be hanging my fixture? 500w at the wall.

Have it at 12 inches but not sure if it's too close

Is it bleaching the leaves at 12"? If not, you are good.

Is that all I'm watching for? If so, no, so that's good to hear thanks

I try to have mine as close as I can so that the lower buds get that extra bit of light . If one or two branches are bleaching, just bend them down

Does this look like it's too much light? This was about 20 inches away but with the reflectors on
