as long as the tubs medium is damp u wont need to check on humidity..but if u can be bothered to put a gage in there 60-70% is fine as long as u have plenty of ventilation..i just hatched some ooths in 85% humidity,,i didnt get any mold cause i had netting over the lid which let all the moisture escape..this is only what i do tho.im not sure what the text book humiderty should be..im sure rick or somone will be by to help u soon.He's interested in specific information - temperature, humidity - you don't give that kind of info in your reply.
