Not Zone 5, sorry, but I have a follow up question.
Just HOW early can you get tomato transplants out -- outside day High/night Low temp? What kind of protection do you provide? What I'm asking is condition outside (air temp, soil temp) when you decide to prepare the protection (usually ahead of time to warm the ground, so.) and what conditions the protection provides to let the tomatoes survive the cold and keep them growing. What about watering?
Do you plant out cool weather crops too?
I'm in a pickle because I may have to boot my cool weather starts earlier than intended to make room under the lights for the warm weathers (changing the temp setting for the area in the process) I'm looking at the latest 12" of snow that fell since yesterday wondering what, if any, possibility exists to set up a poly tunnel right now (I do have a couple of PVC hoops in place, a little higher than strictly necessary or wanted -- they're covering a 4' wide bed at hoop height of about 4'. Nothing on them right now, I'll have to get something to cover them.
