I am using a 1000w hps in a 6x4 walk in closet . I have no exhuast yet I just try and leave the door open for now but it is still hot and i cant leave the door open forever I need help and suggestions I alrady got a fan and a hydrofarm exhaust but don have a clue what i hould do help me please
dude i have the same problem im using 400mh well yours is 1000w too much for the closet i have ventilation and other fans but when i close the door temp increases to 100 i used 250w HPS in my first grow in the same closet without good ventilation but it didnt give my babies much of stress maybe you should think about getiing a 400hps it wont produce heat as much as metal halide and its suitable for closet
Setup your room with a fan on top.Heat rises so what a better way to get rid of the heat than push the hott air that rises out?
