Heat and ventillation

[mr.dirtpots]

im new to growing. i have a 15x7.5x4.5 room set up outside. i need to find out how to be discrete while cooling and venting the room. so any suggestions to go without an air conditioner or to keep the ac hidden would be sweet. the room is fully insulated with a commercial exhaust fan connected to my 600w hps pulling the heat through the ceiling outside. it stays about 70 degrees in there when the lights on and about 65 when off. im just worried when the temp outside gets in the 90s and triple digits, all my effort will have been for nothing.

thanks a lot dudes.

roll it inside and crank it on.
they even have a drip pan of condensation.
