are AC units good at dehumidifiying as well as a dehumidifier ? the temp is 85F in my grow tent and even i dont want to 1 F more heat. there is an exhaust on the back of AC units and exhaust of a AC unit is very hot.i can exhaust it outisde of house.however,a dehuey doesnt have a exhaust. so will a dehuey blow slightly dehumidified warm air ?as i said, in my grow tent, temp is 85F and even i cant endurance 1 F more heat. can i use a mobile 9000btu AC unit instead of a dehuey ?
