Interesting thread. Rain, cold and radiative frost are culprits for most. The latter is my most common issue but that happens only a very few times each year here. We do have an occasional freeze but those are predictable and can be dealt with. Ironically for me the problem is I need heat in the summer for many of my plants particularly Adeniums. It is just too cool here in Santa Barbara a mile from the beach. I had a friend grow several of mine out in Sun City where 110 is not uncommon and they thrived. 5 years on here and although they have bloomed (this year was particularly good due to unusual warmth) they have grown very little and do not bloom profusely like they did in Arizona. So there are quite a number of reasons for owing a greenhouse. Another problem I have is limited space for one.
