Anyone growing in a hoop house?
I have a hoop house that was here when we bought this place two years ago. It isn't huge at 12' W x 36' L x 6.5' at the center. I do not heat it. We are in zone 6a.
I have 3 planters hubby built that are each about 5.5" to 6" deep and 20" wide x 42" long built on legs so the top of the planter is about 38" above the ground. This fall I decided to grow a winter crop of spinach in them. Here it is December 21st and I still have spinach going strong. We've had about 15 nights, not all in a row, that have been below freezing with two nights in the 0 to 8 degree F. range back to back. About half of the nights have been in the upper 20's.
I had no idea what to expect so I was sure to harvest pretty aggressively the night before the first two cold snaps and made sure they were well watered. (Somewhere I read that plants stress less in winter when they have adequate soil moisture.) If I lost the crop at least I had harvested it before hand. This last cold snap I didn't harvest it as it hadn't developed enough after the last harvest but I did water it. Well, low and behold, it only suffered minor cold damage. The leaves that hung past the soil were discolored but not limp. I've no idea how long I'll have spinach but it sure tastes good for now.
Anyone else have an unheated hoop house they grow in during the winter?
