I have been switching my hps/mh every few days. I am curious as if the bulbs life will not last as long? Will this have an effect on the plants? I noticed they do better under the mh, should I keep them under the mh? also my closet grow gets over 92 degrees sometimes, will this effect them?
temperature is around 92deg during the day and 78 at night. some of the leaves have turned yellow and some started curling. the older plants are doing fine without any signs. I think most are suffering overwatering. How high can I raise my 400 w hps in a 3 1/2' x 2' x 10' from floor level? Any help please.
