do I need to harden off seedlings to transfer to cold greenhouse?
I currently have loads of seedlings under lights in my basement. My greenhouse has just arrived! I'm not going to heat it though, I just need more room for all my seedlings. Here's my question: do I need to harden off the seedlings I want to move from the basement to the cold greenhouse or can I just transfer them right away (my basement isn't heated)? I'm only going to move my onions, cauliflower, lettuce, kale, pac choi and sorrel since they like cool temps anyway. Flowers and peppers will stay in the basement for now (I'm in zone 5 Wisconsin).
Thanks in advance,
