There are some factors on How high up to keep lights I’ve always gone off of putting my hand at canopy level for a few and if it gets too hot it’s too close but running hoods with constant air flow I’ve been able to get pretty close but you have to make sure you have enough distance for growth. I run botanicare pro blend grow and bloom with cal mag silica blast, hydro guard and I’ll use advanced nutrients bud factor x and bud candy in bloomWhat are your they?
do you happen to know the height chart for hps?
