We did raise the lights a couple of inches when we saw the leaves turning up etc, what sort of hight should a 400w be from the tops?
400MH...16 inches....400HPS 12-15 inches...above the canopy. IMO. This zone should be at 78 degrees (ideally) with good, fresh air flow.


Not sure what brand of tent it is, got it all in a job lot

I hope, it's not a HydroHut Death Tent?
