I have noticed that alot of you brug fanatics have greenhouses. I posted a couple questions on the g-house forum, but didn't seem like many people must read it, so I'm posting here because it seems like you folks know what you're doing re: greenhouses. Here is a "Cliff's Notes" on what we're doing. We're remodeling a 30x120 building that used to house hogs into a greenhouse. We are going to put polycarbonate paneling on the south roof and the south wall. (Hopefully the triple wall paneling.)We are seriously considering the spray-on foam insulation for the north wall and roof. Now comes the question...........in a greenhouse book I have it says that"if the roof were insulated more than a quarter of the way up from the eave, the rate of production decreased. Phototropism (the bending of a plant toward light) occurred when the north roof was insulated, even though the insulation was reflective." I don't plan on starting plants in this greenhouse, I am going to board already established plants here, I have no desire to get into retail and sell, I just want to "plant sit" for those people who have tropicals and patio plants and have no place to put them. So, if any of you have any suggestions re: insulation on the north roof, I'd appreciate it. I'm going to post a photo of what the inside of the building looks like right now. All replies learned by the University of Hard Knocks will be seriously considered. I should add here that the north roof is 17 feet long, if that makes any difference. TIA
