Paarl In the bright sun and near 60F weather this past weekend, my little hoop-house was heating up. It’s 80F in the picture taken mid-afternoon on Sunday. The vents open automatically at 80, so the temperature doesn’t go above that.
I hope I can figure out how to use my hoop-house this year before the end of April, which is when I put seedlings in it last year. Unfortunately, I’m not sure how to get it to retain heat at night. The big open hoop-house is not like my low tunnel, which retains heat fine. My double-layer low tunnel sits directly on the garden soil in a garden bed and the plants in it have survived all winter. I have a couple ideas for the hoop-house:
1- get a propane heater
2- put the plants directly on the cement on the floor with row-cover over them
I’ll try out the row-cover and see how that goes. I’ll put a flat of soil down there with a remote thermometer on it and row-cover on top. I’m curious if that will work.
