Zygotera, zygolum,zygopetalum outside in summer

I can only speak to the Zygopetalum. I keep mine outside and they’ve done okay going down to at least the mid 40s. They’ve done fine getting rained on too.

My oldest Zygopetalum has weathered lows in the upper 30s, but I’m not sure if all varieties can go this low. A new one that I got in the dead of winter didn’t take the lows well (but it didn’t really have a chance to acclimate gradually either).
