my plants are 24 days old,how would diming my 600 watt mh light to 75% effect my plants?i have it at 1ft and a half above my plants,it gets a lil hot at 100%,when turned to 75% my temp in the closet is a steady 80 degrees.will this effect there growth rate?my plants havent shown any new growth in 4 days now,i think its because of the temps,it gets from 79-87 degrees when my light is at 100%,i have them in a small closet 3 ft by 2 ft.
