Humidity wont get up past 40%!!!!!

[Craiga 01453]

im using aspen bedding right now for both tanks. and when you say regulated do you mean that I can control temps directly with them? because I don't. I have 2 on both sides of the tank that tell me temps and humidity tho. the temp on the hot side is almost always at 90 but very rarely gets to 95 I added that to make sure it was ok so ill watch it closer from now on. again I think I might switch her to the tank that's half the size shes in now. just afraid of stressing them out too much. I understand she might be stressed with a tank this big.

Using a different substrate will go a long way with raising humidity. A coconut coir substrate like eco earth is what I use. I personally blend eco earth and Repti bark and have used it for years.

And you're confusing thermoMETER with thermoSTAT.
Thermometers only read temperatures. Thermostats control it. Just like the ones in houses. You set the thermostat to the desired temperature and it prevents dangerous heat spikes which can cause serious burns or worse to your snake. Heat spikes can even kill snakes.
