I overwinter one worm bin in my basement @ 65-70F. Worms thrive @ 60-80F. If you can't do it in your basement, another option is to get an "underbed" low profile tote and stick it in your tent with pots on top of it. You only need to get into the worm bin every 2-3 weeks. If they have enough moisture (you want to see puddling of .5" on bottom in that size tote) and food they prefer to be left alone. My summer bins are outdoors and temps range from 50-90F. I use fish crates (with lids) and load them with water and enough water and media (soil, leaves, whatever) where I have about a 1-2" water puddling. I feed them 2-3 times a summer (old veggies from the farm) and they do fine. I use the next spring, so I just let them roll through winter (majority of worms die), fill my pots from the bins, restock with old dirt, handful of worms, water, food...repeat...that easy. It's having the container, the starter handful of worms, water, food (coffee, veggie peelings) and letting them do their thing. They actually feed off the bacteria of the decaying matter so having that quietly "rotting" somewhere out of the way is the whole process. No stink or mess. In three (3) months you have black gold.
As I have posted here earlier, we eat a lot of eggs (our own) so I have a old yogurt container (with lid) next to the sink. I put all our coffee grounds (we have three local roasters in a population of 10k...priorities!) and crushed eggs shells in it (with some occasional potato, carrot, cucumber peels) and that gets filled about every 5-7 days. I dump this in the basement bin and it 1) gives them food , 2) grit (egg shells) to digest, 3) moisture (always about a cup of old coffee in there). No fruits, onions, dairy, meat...obvious no nos. Stick to what I do and you are golden.
Looking back at what I wrote and laughed...a 300 word answer instead of "basement is fine. 60-80F".
Obviously I am a big fan....and so are my plants!

. I did find two red worms hiding under a pot today, so I put them in my AK-47 soil. They should be happier there than the hard concrete!
