What range of temps are ok and when does it get to be risky? I'm setting up my first incubator, a Miss Prissy style one. I have gotten to where the light will come on at 98 degrees and cut off at 102 degrees. I can't figure out how to get it any more accurate. The humidity is at 57% with a little dish of water. I also have a small jar (actually a flask lol) of water in there with the lid on. There's also a pc fan running in there, and the bulb is 40 watts. I'm just using a Springfield Precise thermometer from Walmart. I have one with a probe out in my brooder, I'm going to go get it and make a water wiggler to put it in...will that make a huge difference in my readings? I've been lurking in this section trying to gather knowledge, but I'm still a little lost, haha.
