i have a closet that hits 95f i had outtake on top and 3 intakes on bottom still hit 95 then switched it to 2 intakes on bottom and 1 outtake in the middle and one on top but its still 95 i have 2 strong 1 foot fans blowing air down to keep the lights as cold as possible but i think its stopping the air to rise to the outtake so i changed it to face up to blow the air to the top then the closet hit almost 110 was wondering if i could use the top as intake to pull cold air in to the fans blowing down and have my bottom ones as outtakes to pull the air out as its getting pushed down i know heat rises and what not but if im having a huge amount of cold air coming down i think the heat will just stay around the lights if i don't outtake it threw the bottom any suggestions ?
heat rises, cold air sinks. are you using a fan to ventilate the openings? an intake fan is not necessary in that small of an area. use the top to evacuate. get a nice fan that is able to replace all of the air in the grow area every 5 minutes or less. also some pics and a run-down of your setup will better help to assist us in assisting you.
