Ratleanswered grow question 9h ago I'm in Ohio and it is still getting down to the low 40"s some nights and only 60 during the day. I always follow the rule to not plant till after Mothers day at least. Not this year though, still upper 40's at night predicted. As long as I get them in by June doing fine but you've already two weeks into grow. If it was mine, I wouldn't be able to put her out until she was 6-7 weeks into grow. If it's not getting below 60 degrees at night your probably fine.
