LATEST UPDATE:

We have my son’s aquarium all set up and ready to go. The following are the thermostat and temp/humidity readings that have been constant for several days;

Hot side: 89-91 degrees, 51-71% humidity, 66 degrees inside air temp

Cool side: 78-81 degrees, 51-71% humidity, 66-67 degrees inside air temp

I have two sets of Thermometer/Humidity gauges and the readings are taken about an inch above the substrate.

My only concern is that the inside air temp might be a tad low. The room stays about 68-70 degrees. I could add an auxiliary heater to warm it up some. I have no light on the top and have found that placing a couple of wet sponges on the screen top does wonders for the humidity. And then the screen is covered by a towel.

So what am I missing? Thanks
