its kind of hard to vent out the heat from the dehumidifier without raising the humidity back up. if you run the exhaust and the air coming in is higher humidity than what you want, then it defeats the purpose of the dehumidifier.Best bet for temp issues is get ahold of some dessicant and put it in cheesecloth type mesh bags, hang it around the plant site and that should help out with your humidity, combined with the dehumidifier! You can build a makeshift vent to exhaust the heat from the dehumidifier.
