We are using a digital thermometer/hygrometer combo. It fluctuates wildly which is why I think it might be messed up.
The sponge is an interesting idea! I put moss in there but it doesn't seem to be doing much...
Are CHEs better than heat lamps? I really don't trust the heat bulbs, to be honest.
We have a heat pad but aren't currently using it, as the guy at the shop failed to tell us that we'd need a thermostat with it.
We are using eco earth substrate right now, but it doesn't seem to hold moisture as well as it claims.
It's so frustrating! We are trying to do everything right, and things just aren't going the way they should. Sigh.
