How cold is too cold

[stealthk7gsxr]

I have a 10 gallan tank. I have a rather large UTH as it cover a little over half the bottom and a heat lamp on the warm side. I put in a higher wattage bulb. I'm now using a 75 watt bulb and was using a 40 watt bulb. I have the top covered completely except for a small place where the heat lamp is to allow fresh air. I have half the top covered using a wet towel to help with humidity and the rest is covered with aluminum foil.

Right now the temp inside the hide is 93 deg. Ambient warm side is 84 and ambient cold side is 73. Humidity is 49%. I use an acurite to measure temps.

It has been raining most of today so the humidity is higher than normal plus it is 60 outside right now and 64 inside my house.

I'm looking into getting some insulation board. If that don't work when it is really cold in here then my sister is going to take my snake for the winter.

that uth is ok, but heat rises and with the temps in your house bein low as they are it will dry that wet towel with the warm from below and cold from above and make the towel cold in the process. i know you konw what a wet cold towel feels like, so that idea is just making it colder in your tank. if your dead set on keeping your snake with you during the winter i'd suggest a few fairly large "dry" towels and your bulbs. i konw you said the wattage of your bulbs, what what type are they? not regualr light bulbs right? and what are you using for night heat when you shut those lights off? try the dry towel method, along with the ceramic heater (which can stay on constant) and alternate with a heat bulb for day and night. humidity should be your least of concerns right now. you can always mist with a spray bottle for that. keep your sister on speed dial in case that temp drops lol
