I grow mine at 25ish - where the doubling time is about 10 hours, at 15C it's more like 20hours. If you shove one in the fridge it'll basically stop - but not die. At 35 physarum liquefies and stinks ( thermostat mishap). You've reminded me to get the incubator up and running.. I do wonder about temp preferences between strains now - but difficult to study with a home made temp control system.
They are highly thermotactic - I've played around with peltier blocks under the petri dishes but didn't build the heat syncs robust enough to keep them running well but you can 'steer' a slime with one block set to hot and the other to cold.
Thanks Ian, that's interesting info.
I've got a couple of peltier devices knocking around somewhere so I may have to dig them out.
