oooh 32 is high! i heard marijuana tolerates 21-29 degrees celcius, Do you have air being sucked in from outside? does air flow into the room? because if theres no airflow all a big fan will do is move the hot air around, not cool it down. My fan sucks air from outside keeping the room cool.

UTI i dont know how to lst?? whats the point of lst by the way? to keep the plants short?
