Put your hand at the highest point of the plant, if it is uncomfortable for your hand (too hot) your lamp is too close

as a rule the hps whould NOT be closer then 20 cm .
and I don't think it should be higher hhen 60-80 cm.
so at about 30 cm from the top of the plant would be good.
peace!

Thanks,guys.I was concerned also about some plants being slightly taller,and maybe burned by going too low.Butt,the taller plants have the best buds,so i'll defer to them,and deal with the lower plants later.Thanks,i'll take your advice...
