Yes, temp, pressure and humidity are all relevant. As long as you don't live on the moon or something, you can ignore pressure's impact for these contexts.
Humidity is relative. A higher temp but equal % humidity actually has more evaporated water in the air than a lower temerature.
Slow and low, like ed rosenthal says. Lower temp, appropriate humidity will cause the right pace of drying.
In general, as long ast it takes 5-7 days orlonger to dry (stem snap), it's probably going to perfectly fine. If it takes 2 days and is already crispy, you know that's WAY too fast.
So, a <=60% humidity to avoid microbial growth is good and will slow the drying. If i recall, temps sould be in 60s? I don't control these things. I just make sure it takes at least 5 days to dry. I'll open or close container (not sealed) to speed or slow the process down. In a drying net, you can black off the sides with soemthing and do the same thign. Place in corner and rotate to keep it even will slow drying, for example.
In winter, i have to do things to slow it down due to ~35RH%, otherwise it dries in 2-3 days and even with a boveda pack reconstituting it, it doesn't turn out as good as expected. In summer, i have ~70-80%RH... it takes 9-10 days to dry, but that;s still okay.
As long as it doesn't start growing funky stuff on it, it's not too long of a period. Start going longer than 10-14days, maybe it's an issue? i'm sure google can provide more details on that sort of general rule to follow.
look up ed rosenthal. He's got a good write-up out there about drying/curing.
