I use a CHE (same idea as it bulb) regulated with a Herpstat. I have a custom plywood enclosure that holds heat and humidity pretty well and well ventilated. I use cypress mulch for substrate and it balances the humidity sucking power of the CHE really well. I water once a week and it holds around 60%.

If you use a towel or even cut an acrylic sheet out that would help it a ton. Never had a bad shed and my girl is quite happy.

Hope that reassures any doubts you have. My surface basking spot is between 90-93 and cool is 78-80. The rooms ambient temp is 68-70.
