Take some white paper plates, cut to the middle and at the middle make cuts like a star and then slide one on each pot careful placing the plant in the middle.
This will reflect some light back and also stop the fugus flies.
Also it REALLY is all ph. You must control it at 6.8-6.2
In the big tent I'm currently using a switchable 600 MH ... I'll switch to 600 HPS when I start to flower. I heard that 18/6 vs 24/0 doesn't have any advantages and it costs an extra 8 hours of light .. also, the roots grow during the off hours? I'm sure some strains work better than others with the schedule differences. So far (crossing fingers) I haven't had any issues w/ flies. I have the yellow sticky paper down for preventative measures. I'll get an occasional fly here and there but I think it's more from when the tent is open while I'm working on the ladies.
