I think I already mentioned it but look on amazon for the acurite 00891, it gives you a probe for the hot side and then cool temp and humidity also by placing the unit on the cool side. They are really acurite, reads same temp as my herpstats and ve thermostats and I own 11 of them lol. As far as keeping humidity in just cover the lid with aluminium foil or Plexiglas and just leave room for the heat dome. Did you place the heat dome over the hot hide? If not that is something I would personally do, just make sure to check the temp inside the hide if you do this. No matter where you have it make sure to check the temperature of top of substrate where the middle of the bulb beam hits bc that's where it will be hottest. Also you may want to cancel the order for the rheostat if your getting the thermostat, or you can keep it as back up or use for the heat lamp if your cool side temp doesn't stay within 78-82.
