Scarecrow...
Sounds like you have the right idea... gring in cool fresh air..
PULL out warm old air...

love

thats the problem no cool air the intake is pulling in fresh air and exaust is vented directly out side but still hi heat and low humidity maybe if i moved the hps lights and vent fan to top of container it would help but what about humidity ? always had successful grows new to cabinet setups heat is definatly the issue here any sujestions would be appreciated
