Okay, so I have a 7 level AP rack that I finished setting up about 2 weeks ago. I use cocohusk substrate, space heater for ambient, and heat tape for belly heat with a herpstat 2 hooked up. I have the prob on the middle level. So, I’m having trouble with certain levels getting to the right temp(trying to hit 90-91*). The level the probe is on is getting to the right temps, as well as a few levels below and 2 levels above. The top level is only getting to 85-86*. If I raise the Tstat, then the tubs getting to the correct temp get too hot. Idk how everyone gets each tub to the correct temp on heat tape that’s snakes through the rack and not hooked up by each individual level. Thanks!
