I started my impatiens under lights, too. They're ready to escape. All we need is some nice, sustained warmth. I hope that's here now to stay. It's 35° now, and a warm forecast going forward.
I had started to harden off my indoor coleus and the few seedlings that I started under lights. Now they haven't been outside due to cool weather and wind for the past week or so. I'll have to start over on that hardening off process. I can't wait to get everything in the ground and final bigger pots, too much work inside.
That might be my favorite thing about wintersown stuff- no need to harden off!
