I checked the "babies" this morning and I see tow little green sprouts still emerging from the seed in the Stevia 4-pack. When first planted, I didn't use any bottom heat but I think I moved it to the heated holding flat a few days ago. I sowed the seed on 2/16.
I'm using Gardener's Supply Organic seed-starting mix for the first time this year (a Christmas gift) and I'm very nervous using it because it's a lot heavier than their standard germination mix. It holds a lot more water and I know from all the input that Stevia doesn't like to be wet. So I'm being very cautious with it.
