I have a grow area of about 48x42x72, Lite by 1k hps and a 300 cfm fan pulling air. my temps are hitting 100 constantly. I also have a little fart fan about 100 cfm pushing in air to help cool it but not very much. what can i do????

Make more intake holes. Make them all passive intakes. No fans. get rid of the little fan it is jamming up your airflow. You have a 300 cfm fan pulling air but it can only get 100 cfm from that little fan.

I bet if you just remove the 100 cfm fan, but keep the space where it was at open you will see lower temps.

Whatever size intake hole your 300 cfm fan has you need to have 3 passive intake holes that are each the same size as that one. Or one intake hole 3 times as big as the exhaust hole.

remove the intake fan and get a bigger exhaust fan.
