These styrofoam incubators, LG and such, how much water should be put in the little water areas below? What is the best way to regulate humidity? Is it a matter of adding or taking out water? The new bator I have has a temp and humidity gauge but on it, it says 'Reference only' when the thermometer that is build in reads 92 the inside one I placed in reads 99.5. The humidity reads 69 or 70% which from what I am reading is to much? (We're on day 8) If even that gauge is correct, I won't know until tomorrow when I buy one and add it. Any advice on regulating humidity is appreciated.
