I dont have a way to measure teps accurate
You MUST know your temps at all time, same thing for humidity.

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)
