I don't know what the conversion is but no T should go under 16c for more than three to four hours, the results can be bad, very bad. Best way to go is to find out the relative temps in the area a particular T lives. Rosies will handle the cold better than practically any other T (except maybe Selenocosmia himilayana, it's amazing where those T's are found) so don't guage temps from this spider.
Doesn't it get winter in T land? I mean, don't every spider have temps below 16c of 65f in the winter? :?
Not all, but some do yes. Don't forget that T's burrow (with the rare exceptions). Some areas that T's inhabit can go below 0c (freezing) for a brief period, but deep in the burrows the temp will sit on a constant average of about 22c. To determine this all you have to do is look where T's live (on average). Tropical to subtropical regions, where the ground temp sits on a nice constant, even though the air above ground level fluctuates, sometimes dramatically in contrast.
PZB's are from Paraguay, which is subtropical to temperate climate. This from BBC weather: The northwestern part of the country lies entirely within the tropics and has a typical tropical climate with hot summers, warm winters, and most of its rainfall in the hottest months between October and March. The southeastern half of the country has Temperatures a little lower in all months, but the summers are sufficiently hot and wet to be typically tropical. Paraguay is entirely landlocked and is situated between 18° and 28° S.
Sort of like when my uncle came to stay with us.
I know, but T.s are cold blooded and can have their temp dropped. Even so, at what point do you draw the line? All of them flourish at different temps but do each of them have a specific degree where they just roll over and die?
Yes I know they are cold blooded but that doesn't mean they have to be kept Cold.
I would not consider a "Mini Kritter Keeper", 6L x 3.5W x 4 H, too small for a 1-inch sling, as long as you include a small hide within it. It's first molt it will get a lot bigger. They usually recommend attaching a heating pad to one side of the keeper to give the T a choice and to avoid over-heating. If you fill it up with soil 2+ inches, then the pad can be heating the soil on one side.
