Good luck seedling?
 

My serranos (and other hot peppers) are just starting to get their true leaves and that's when I transplant them from a densely planted cell with multiple plants to square containers. I had to continue with the 3 cotyledon seedling right? Maybe not as uncommon as a 4-leaved clover, but still it's good luck right? While all my hot peppers are small at this point, their root development was very good.

That looks really nice. 8-)

Now that's an auspicious start to your peppers!
