i am feeling this pain right now. Brought home an LG from 4H, and it was up to 109... I didn't know incubators could go this high.
From what I've read, and my experience, they like to be in a room with constant temperature (and humidity). I had my best luck in my basement. My house can vary add much as 20 degrees due to set back thermostat and sun heating. My basement is cooler, but more stable. Just my experience. I do better with a converted mini fridge with light bulbs and a water heater thermostat! (and some water bottles for temperature buffering)
