I have a 32qt tub with a Ranco 11" flexwatt on the warm side. I have my Ranco up to 100 and only getting a 88-90 on the warm side in the hide. Under the newspaper in the tub I’m getting about 91-94 I have the probe taped on the flexwatt right at the edge of the tub. I tried it under the tub and the tub was uneven. My question is how high should I go on the Ranco? What is the normal transfer difference from flexwatt through the plastic through the newspaper. also only have 2 sheets of newspaper as substrate. My 1st snake was postponed do to cold weather here and I have to wait one more week.
