It's not ideal, thats for sure, do you have a air cooled hood or no? its really helped me out, w/o it i cant keep them under 95-100, with it im sitting at 80-88 at 6 inches from the light where the plants tops are at and the lower you go the temp gets cooler.
I've been keeping my lights off 10am-4pm during the day, the temp stay under 90f but the heat it releases into the house is not acceptable to me, its hot enough already during the day w/o the extra heat it makes.
