i have a likkle heat problem, just want to make sure i dont harm my buds. right now i have a scrog setup in a room 3w by 3d by 5h, with 4 sativas now going into flowering for the 4th day, a 250w hps light, 3 pc intake fans which are doing their jobs, 1 8" table fan and a hole at the top of the room about 5" by 3" just to let hot air go out, i also am going to make use of this hole when i buy my new 6" exhaust fan. when the light is on the temp rises to about 87C and drops to about 80C when it turns off. my plants don't seem to be affected by the heat or anything except for the tips of certain leaves turn brown from he hot air blowing on them. what can i do to keep my room cool while i wait on my exhaust fan, or am i safe at 87C until i get it?
