siege2050

It got down to 12F last night, and to my surprise, everything survived under just a layer of leaves, and leftover greenhouse plastic with small bulb christmas lights underneath in the single layer greenhouse. I was sure they were goners, It got close as the condensation was frozen under the leftover plastic except where the christmas lights were. Now that I know it can go so low and stuff stays alive, I am going to order the frost blanket, and a roll of reflective mylar (space blanket) to go over the lights to keep heat in. I think stuff might actually survive down to 0F outside while in the greenhouse with this extra protection. This might not work in a smaller greenhouse where the temperatures are less stable. I am also going to get more christmas lights, the thawed sections of the plastic proves the need for them. Also if you have naners in pots, you might try laying them down closer to the ground for warmth and covering. I will probably chop all my ornamental naners down to pot level to make covering easier next year.A thermometer I lay on the ground under the leaves shows the ground surface temps in the greenhouse stay about 44F even when it got down to 12F outside. C9 lights are a big no no under all that stuff, I can just see a fire.
