Does anyone know what over night temperatures are safe for ant plants when being grown outside? I found this one website which says night-time temperatures should never fall below 18-20° C.. Isn't that about 68° F.? It's already been cooler then that overnight. I thought they might be safe to about 50° F.
These are all lowland plants. Ideally, nights should be in the high 60's into the mid 70's. That being said, mine get down into the high 40's at times. It greatly slows the plants down but doesn't seem to harm them otherwise.
Spend your life doing weird things with strange people.
