I am measuring my temps with a Pro Exotics PE-1 Infrared Temp Gun. The probes connected to my Herp 4 are in the groves premade by AP, under the cage, and on top of the Flexwatt. Would it be a better to place the probes in the enclosures instead like in your pic, Serp Merch?

I boosted the temp in one cage to 105F and 100F in another. I will wait a few hours to see how well the enclose and substrate are heating up. Ambient temp in the cool side is around 74F. Since I live in an apartment the cages are in our living room and I can not raise the temp higher then 71F. Perhaps a RHP is my next step. I was really under the impression the Flexwatt was all I needed hence my frustration.

Thanks for the advise everyone.
