Here you go! It's nice, not too expensive. Doesn't have a temp cutoff function (easily fixed with an Inkbird controller) but I really like it. Perfect for my 5x5. My tent is in a basement that doesn't get above 68 on the hottest days of the year so it's essential! https://www.amazon.com/dp/B076J929TG/ref=cm_sw_r_apanp_FC4U6Lj6sQODA
IMO this is an essential piece of equipment for herpers. Keeps ambient temps to a sufficient level that heat pads, etc can do thier thing (provide hot spots.) they are quite reasonably priced on Amazon.
One word of advise, DO NOT get an all digital one as they will not come back on after any power outage. Make sure to get one with a physical switch.
I have a full sized one but recently switched to this small one and it’s awesome.

Good luck!
If I were you I would get some heat source. A space heater with a thermostat knob works, albeit higher fire danger than an radiator heater ([like this](www.amazon.com/dp/B076J929TG/ref=cm_sw_r_cp_api_Sbb3AbCYPRG9H))
Turn up the heat and let dry out for a couple days.
I use this guy in my 4x4 on an Inkbird. ✌️
