OK... here's an update. Garty's been brumating for three months now, and it seems like he may be losing some weight (I don't have a scale, just guesstimating). Looks like it's probably time to bring him back up to temp and see how things go. His brumation temperature has been a pretty consistent 51F, and he had a complete shed about a month into it.

So... how fast should I bring his temp up? I moved him today to the next coolest location I have, which will probably be in the high 50's (I'll have a better idea tomorrow, when the cage and thermometer equilabrate). How long there, and then what?

Also, is our NW WA natural photoperiod (still short!) going to cause problems? Should I match it with his artificial light or what? And at what point should I re-introduce light during warming (he's still covered at this point)?

Thanks!
