Hmm, I'll continue thinking about that...

One more sprouted this morning. I shall call it Theta!

alpha: Day 8 since sprout
beta: Day 8 since sprout
eta: Day 2 since sprout
theta: Day 1

The stems on a&b are noticably thinner than e&t. Could this be due to the fact that a&b tumbled a few times? lol
