keeping them warm

I left the cover on until 12 noon today to give the plantings some more warmth. I took it off at noon, though because the thermometer inside the frame read 21°. Tonight I put the cover on at the lowest setting (up until now I had it as open as possible.) I’ll see if this promotes growth.

So far, I can’t tell if the little platns I see are mine or just weeds.

I’m planning on fertilizing again tomorrow.
