I am getting one of these, the kind you see in grocery stores by the checkout with soda inside, and would like to know if 54 degree low is OK. I spent the winter moving my high elevation Neps into an aquarium in an unheated room and now with warmer temps want to do the same only have the damp aquarium inside the cooler. Without stirring a controversy I mainly just need to know if a 54 degree low will suffice. Moving the plants over the winter like I mentioned worked great, I kept damp NZS in the bottom of the aquarium (maintaining 100% humidity) with a lid on and sprayed the plants before placing the aquarium in the cold room each night. Once my collection outgrows this system I will come up with something else but for now it works.
Forgot to mention that the macrophylla thrived in these conditions and is now beginning to produce larger leaves and a ribbed peristome. I have a villosa arriving shortly that will be a good test subject for my technique and I'm sure it will let me know if it is unhappy........right?
