I've built my bator for the online contest and now I am in the process of tweeking it before I post it. The problem: Thermometer reads too different temps that are about 4-5 degrees apart. The indoor temp ('bator temp) ranges from 96 to 99 and the outside temp (homemade wiggler temp) usually stays at about 101 (yes I realize thats too warm for eggs). Used 100 w bulb and an accurite themometer. How do I get them to be closer?
