They look great! I wish mine were doing that well. Mine are 2-3 weeks too, but maybe 1/4 the size. I'm having to re-use my old potting soil because of the lockdown. I wonder if it's depleted of something, perhaps Nitrogen? Or maybe I should do a pH test and see if they're having trouble absorbing.
Astro Beaver, I should try some of those seeds sometime soon.... it sounds yum : )
