For those who haven't yet tried vermiculite sowing, here's a great example of how the seedlings look...root and all. They won't grow much if any more without first being transferred to growing medium. This one has used its stored energy to get to this point, and will need a boost to grow any further. This seedling has been sprouted now for 10 days. It looked the same on the first day as it does now. No tangled roots or packed-down medium to deal with...just lift it out and toss it in some growing mix.
Crotalaria sagittalis-
(It looks huge
, but this is a small 16 oz container, roughly 3" high)
