Substrate temperature

The bulb is a 60 watt. I know this is a bit over the maximum but it was the only one I could find at the pet shop, and without it the enclosure is dangerously cool. I weighed out the pros and cons. As soon as I find a 50 watt I'll use that. I use a full spectrum blue bulb during the day and a red bulb at night. It does have a dimmer. The substrate wasn't hot. It was just warm. I don't know how far the heat penetrated.

How deep is the substrate? 60 watts in a full spectrum bulb is pretty hot and bright. Warm isn't bad. Think of the sun warming the earth. You should be fine as long as it actually doent get hot. Check the temp with a glass thermometer of the tube kind or even the oral electric ones. See exactly how warm it is and how far it penetrates. Also when you mist it cools the air and the substrate for a short time as well. See how warm it is. You have a temp gradient in the tank don't you? I assume you do so if your frog gets too warm he/she will go and cool off.

Yeah it is. I mean to get a less powerful bulb, but neither bulb seems to be causing problems. Plus the inside of the tank has to remain about 20 degrees warmer than the house. There is a temp gradient and shade, so I guess it probably isn't an issue. I will check the substrate. Thanks!

Should be fine with the cover.
