Hardening off help
Here in zone 7 our weather is very unpredictable during the time when I need to be hardening off my "cold crops". I have cauliflower, Brussel sprouts and cabbage that I started several weeks ago. All are getting to the point of having several leaves but are still pretty wimpy. I started taking them out last week to harden off but only got to do it two days. It is now WINDY and too cold for that! I have a cold frame built and sort of a glass tunnel made from windows that I use when hardening and what I'm wondering is.....at what point/temp. can I just leave them outside in those? I can obviously protect them from the wind but what temp. can the cabbage and cauli withstand?
