I plan to brumate gerry in the fridge.
-A few questions I need answering
I found two spots that would be suitable.1st stays at 11*C,2nd stays at 8.4*C .

Which would be best to put her?

How do I cool her down slowly without giving her a shock?

How long should I brumate her for?

How big should the container be? (she's 16cm)
Ta in advance
