Hi, everyone,
I’ve been preparing the fridge these last couple of weeks in readiness for Harry’s hibernation, and have come across a bit of an issue that I’d like to raise; perhaps someone could comment or advise:
Using two digital thermometers, I suspended the probe of one so that I could read the temperature of the air in the hibernation box immediately above the substrate, and the other probe, I put into the substrate itself, about one inch down.
After a couple of days, I was surprised to see that the temperature of the substrate was consistently about 3° lower than that of the air above. Therefore, would I be correct in saying that when regulating the fridge temperature, we should aim to attain the optimum temperature of the substrate rather than the air itself?
I did check these temps using different thermometers, but the result was always the same.
Any comments or advice would be appreciated.
Many thanks,

Oooh that's a tricky one! :)

I think as the temerature has to be low single figures (I aim for 4C) you might be able to get this mid point anyway? I fill any spaces in my fridge with plastic bottles of water. This helps to stabilise the fluctuating temps?
