So getting my first BP tomorrow and I have a tub. The hot spot under the paper towel is reading well goes up and down from 86 to 94. Thats cuz I have a Hydrofarm tstat. anyways the hot spot on the paper towel is reading about 84. I am assuming once he lays on top of the paper towel the real temps will come through. The question I have is When I first put holes in the tub I did just enough to test the humidity. It was at 81%. I added more holes now its down to about 58% been like that for about 4 hours now. Is the humidity at a proper level? lol sorry for the long post just wanted to give some back ground. If you have any pointers for the heat that would be great to. Thanks! Mitch
