I love auto pilot! Over the years I have spent countless hours roaming the Depot in an effort to address things with the GR. Oddly enough, they don't sell jars.
I am glad things worked out for you. The paper towels just make it easy to know if they have popped or not. That, and it works.
I would put them under some light for sure. They are looking for heat and the light is what will bring them out of the dirt. For now, just water. I would wait until they grow a few sets of leaves before I fed them. They already have enough food contained within themselves to get there without issue.
The day you can enjoy your own medicine that is pure and delicious, is one of the best days to have IMO. T minus 3 months and counting.
