psychopsis winter temps

[weederwoman]

I would love to try a psychopsis hybrid, but I read that their natural habitat has 80 degree winter days. My greenhouse is in Oregon, where winter sun is rare. Temps rarely get that high in a greenhouse where the heat is set to go on at 60 degrees, like mine is. It will be under winter lights. I could put in near a seed-starting heating mat if necessary. I have found little mention of necessary winter highs in my research so far. Thanks
