In MI I wait until we have 13.5 hours of sun and temps in the mid 50's- 70F. Then I place my seedlings in the sun and watch them. First sign of wilt or droop, in they come. And try again until I can leave them in sun all day. Some strains there is no issue. Others take days to harden. Just don't toss them outside and call it good. It is a easy transition.
