Thank you for the detailed reply. You’re definitely right on 1 and 4, and got me worried about temps. I set the thermostat to 100, so that the tub is at 96, but the upper layer of reptichip is always at 85sh.
I was told that the temperature of the tub itself is the important one, not on the top of the substrate. Should I bump up the heat?
Top of substrate
Tub temperature
Where I have the thermostat sensor. It’s directly on top of the heat panel
