After reading your suggestion and hearing from many others I finally picked one up at Petsmart. It is a All Living Things Digital brand thermometer and hygrometer it wasn't expensive at all 20.99 so thanks for the suggestion. Don't know if it will give me past readings but it will give me at least accurate present readings. I had 2 of the cheap type stick-on which having 2 put me in the ball park but now I have something a lot better to help me with temps and humidity. I got the same brand climbing branch to give my girl something to climb on, rather than them cheap sticky's.Any suggestions from folks here about the placing of the main part and the placing of the probes? Warm end, cool end, in the middle?
