I did, however, buy a small DIY greenhouse the last time I was at a home improvement store. It's six feet tall by about 3 feet wide and 3 feet deep, and I could probably set it up outside our basement entrance doors on the brick patio out back. That would protect the plants from the wind and rain, but they would still get the benefit of the temperature drops, right? I'd feel more comfortable setting my phals and paphs in some sort of sheltered environment if I was going to set them out overnight. (We have a lot of munchy critters to contend with, too).
Out of curiosity, if I were to put the phals and paphs out overnight, at what point would I need to bring them back in again? Just before the first frost? Thanks for your wisdom, everybody!
