>>1216124>zone 7a (detroit)I think its last frost date is May 2? If the temperatures at night can be at or above what the seedlings need then yes you can put them under some polytunnels or other type of sun-warmed shelter. You may need 2 layers of plastic and some black-painted bottles/containers of water in under the plastic with the seedlings. I'd set it up and put a thermometer in it for a few days to make sure it would work.
>>1216129Pretty amazing.
