Another experiment. Ponytail Palm seeds.
I decided to germinate these in moist paper towels. I spread the seeds out on one half of a moistened paper towel.
I folded the paper towel over, and moistened that side as well.
The paper towel is inside a tupperware container.
I was not sure whether it should be sealed or not, so I left one corner cracked. I placed the tupperware container in a dark drawer, and will check it regularly.
