Cold Frame Progress

I put the cover on the cold frame today. (yippee, I figured out how it fits without asking my husband for help, lol).
There were a couple of small sproutings visible already, but they could also be weeds.
I’m not sure if the plants really need to be covered yet, but I’m going to experiment with leaving them covered with the frame open to vent overnight and removing the covering entirely first thing in the morning, see how it goes.
