keep humidity below 50 late flower and they will be fine
had rot problems myself above 50%rh
good point but if using gavitas and you have adequate height like 12ft high or higher then 2x 1000w+ gavitas then over a metre maybe a metre and half from the canopy for most power down and best footprint,,,different strokes for different lamps,,,s2Yea but don't forget that distance to the light can make a staggering difference as well. I've grown on 400w vertical with huge nugs and grown small buds with multiple 1000w. I'd rather have the plants 6-8 inches away from a 400w than 2-3 feet from 1000w. It's a mistake I'm guilty of making myself in the past and judging from many people's pics I see online it's a mistake a lot of others make as well.
