Sadly, no greenhouse! My neos are growing around the kitchen sink in a east window. Temps upper 60s, RH, lower 30s. It might get a bit more humid at times during the day, depending on how often/how long the water is running, but probably not much. I also grow my angreacum didieri, a leptotes bicolor and African violets there as well. The leptotes might need more light, but everything else is doing well there.
I've been thinking about unpotting it because when I water it, I get a whiff of something off. Just want to see what's going on in the pot. But because of all the root growth, I doubt I'll be able to get it back into the same pot, hence the basket idea.
Once active growth begins, my choice would be an open basket and tie the plant in place if necessary until it becomes established and attaches itself. I'd put a few very large chunks of orchiata bark in there for the roots to anchor themselves onto, maybe a few big chunks of lava rock or some larger broken clay pot pieces and maybe one or two big chunks of diatomite if you can find them. I'd aim to keep conditions quite open and airy around the roots with only a small amount of water retention. Just be sure to maintain good humidity and a sufficient watering and fertilization schedule; otherwise you may want to use a pot with a hollow-centered mound of sphagnum.
