1000w closet grow heat trouble.......

i am using an air cooled 1000w light in my closet. a 400 cfm exhaust connected to light removing air from it. i cannot seem to get the temp at the tops of the plants below 82-84. i have heard that mid 70's is best???????? also, my light hood has a opening on either side. i have exhaust hooked up to one side and other open. is there a more efficient way to remove heated air from light????any help is appreciated thank you

how big is your closet..? sounds like you need to try a 600w in there

Is your light sealed? Does it have a glass plate? Are you exhausting the air out of the room? You have a passive intake?
One solution for you might be to attach duct to the open side of the reflector and pull air from outside the grow room. That way the air that is going over the light is cooler.

light is sealed. has glass over it. passive intake no!! i have duct exhausting from one end of light. i am reluctant to get an inline fine cause i will have to cut a hole in the closet door to suck air from outside closet. i am going to do it i think.

do these look un healthy/.

Good lookin healthy plants man, you really just want to make sure it stays below 85 but like 78 is ideal. yea intake would be the easiest fix
