Your seedlings are looking GOOD! :) I love how you make the most of what you have available to you.
Thank you for your kind encouragement. There are 3 and a half boxes all told*, and the larger plants are almost 6 weeks old! But I had some help, by the grace of God. For (if may bend your ear) you see it was a very warm day about mid-March, and you know, you just feel like Spring might be on the way, and you are eager to get a head start. So - and wanting to give some of the (pre-COVID captivity) neighborhood city kids outside something to do in the garden plot (as last year) - I showed them how to mark the 20oz cups and fill them 2/3 full with the homemade potting soil, then put 2 seeds in (from last year's crop), separately, and then cover with soil, pat down and then I watered them, and the "nursery workers" took a couple home.
I later took the plants inside, upstairs to sprout, but since I do not have any window to use in a warm room that gets much sun, I used grow lights for about a month. When 2 seedlings come up in one cup, I try to separate one to plant it in a new cup of soil. I also planted a few more.
About 2 weeks ago I put 2 boxes outside in the sun when it was about 53 degrees, but about half of them died, not being hardened off. After that I put the most mature ones in a cool room that gets just a few hours of sun, and they actually grew better than being in a warmer room under grow lights and less sun. Praise God.
