I lose them in trees and other vines once in a while , What makes it so nice if it works that way growing them is that plants that will grow in a lower temperature to begin are often stronger here ,
The never below 50 degrees limits growing here because it makes them more likely to have mold or mildew or fungus , so on , That they would grow at 40 degrees as weather warms and falls cold again is a real hope , Besides it often goes right to the 90's from those 50 degree temperatures making plant stress part of the difficulty
