Hi Dan and other micro growers!
Just checking in to see if it's time to cull this batch of seedlings, sown on 3/15. Since it is an F3, all the tall ones should go, right? Then I'll look to save the ones which leaf out at the shortest height and check also for stem sturdiness? Culling = Hard
The cotyledons of some seem to be getting pale so I'm not sure if they don't have enough space (in about 1" of mix and 1" or less from neighbors in all directions), or if after 3 weeks they might need some ferts. New Project = Worry
Thanks for guidance,
Kath
