Bob, you started earlier this year?
Sneaky. My 11 variety grow became a 12 variety grow today, when I located the Besuki from Tutu, and discovered that there was Besuki from Kesilir as well as a different Besuki from Ambulu. (Maybe there was a 3rd one that I didn't find today.)
When a variety germinates, and the required seedlings are transplanted to cells in a 1020 tray, I replace the lid, and continue it off the heat mat, like a closed terrarium. It receives only indirect sunlight. If a transplant in a cell fails, I still have more. Kept in the jars, the seedlings remain fairly tiny. I've had some of these closed jars maintain tiny seedlings for well over a year, without the addition of water. (These superannuated seedlings are not of much use, since they have survived by epigenetic changes that cause them to immediately die of a heart attack when planted in a more favorable setting. But they're cute.)

I would plan to start seed for the plants you will require. The small potted plants may actually grow well, once they are transplanted outdoors. I have done this with plants in uncovered 3-1/2" (~9 cm) pots that had been growing indoors or on my open porch for over a year. Most of them grew to normal size, once planted in the ground.in small pots to test germination (about 2 month and a half ago already).
After they germinate, I let the pots (not closed)...

I suspect that the "terrarium" seedlings lose their ability to limit their water loss, and just promptly dehydrate when moved to an open container.
