Yet, despite the cold in the sunroom, the lettuce still looks good. It is in front of the frosty windows!
It's growing slowly, but that's to be expected when the temperature is 14 degrees outside and the sunroom is unheated! I do plan on planting some more cool weather things in the sunroom, but I think I'll wait a few weeks before I plant seeds for the spinach, more lettuce, and carrots. And maybe some radishes. I've got gardening on my mind, and it will be a long time before I can plant outside.
