I am getting a 20 gallon long ready for my first ball python. I have been working on the heat for about 2 days now. Is this acceptable: cold area: about 72%, warm area about 82%, and hot area about 93%. I have an inexpensive thermostat in the cage now since I can't afford a couple of good ones until next month. Will these temperatures be good enough.

Thanks,
