i didnt use humidity gauge at all so i dunno how the humidity was , i dont think theres humidity in the ground in the first place so just moisture , so just make sure your subsrate it moist and not wet and your eggs will be fine , just mist the tops of your tuper wear containers every 3 or 4 days or when ever the moisture has evapourated off the tops of the tupperwear conatainers thats what i do and works perfect for me , just dont soak the tops , there is also a resivour on the bottom of incubators for water so just fill that up so it doesnt take moisture from the containers holding the eggs and they should be fine , but if i missed anything just msg again me or kinyonga will help you out
