I have another greenhouse question for you people........what is the minimum night temperature I should shoot for? I was thinking 50 degrees for mature tropical plants. Ferns, brugs, hibiscus, etc. At this point I have no plans to start seeds and such, I will just be doing the plant wintertime boarding. Anyone with ideas?? Thanks. Oh, by the way, the GH is coming along very well. The insulation on the north wall and roof will be applied next week, as will the polycarbonate paneling on the south wall and roof. Here is a photo of the south roof, waiting for the paneling and rafters. The ventilation fans are installed, as are the motorized shutters.
