You MUST know your temps at all time, same thing for humidity.I dont have a way to measure teps accurate
I would suggest you to go to Walmart and get the following DIGITAL thermometer/Hygrometer, it will cost you about $12
Your temps should be 80-84 on the cool side and 90-94 on the warm side.
And remember anything below 75 is unhealthy and will increase the risk of RI (Respiratory Infection)
