Sowing Eggplant, Thyme, Marigold, and Pepper Seeds

I started some new plants today, and I found it was super-easy because I purchased a couple of "greenhouses".  These include the tray, a clear plastic "greenhouse dome" and 36 pellets (or "plugs").  For only $5.00 apiece at Ocean State Job Lot, this seems like the way to go!

So easy!  I filled 2 trays with warm water until the pellets expanded into little pots with soil.  Then I put a seed or two into each one, covered with a little peat moss, put on the dome and finished!  I didn't forget to label the trays, so I won't forget which plants are growing in which tray.  Then, I placed them on the heating pads in my bedroom.  And, I won't forget to take the domes off and give the plants light as soon as they begin to emerge!

What I'm growing: 

• German Winter Thyme:  14-21 days to germinate (this took 3 days with heat)
• Eggplant, "Galine" (this took 5 days with heat)
• Marigold, "Snowball":  7-14 days to germinate (this took 2 days with heat)
• Pepper, "California Wonder":  10-21 days to germinate (beginning after 7 days, but slow)

These are the thyme sees, after just 3 days.

April 7 - These thyme seedlings are now a week old, and still tiny-tiny.  I wonder how I'm supposed to thin them and transplant them, as they seem so small and delicate.  I wonder if I should have sprouted them in wet paper towels first, and then transplanted each one in its own, separate pot?  Maybe I'll try that next time.

Here are my eggplant seedlings after 7 days.  They look pretty good:
