I collected about 40 or so persimmons seeds last fall and have had them wrapped up in the freezer for about 3-4 months at this point.

I'd like to get them started but I'm looking for a good way to do this without spending a lot of money on 40 1-gallon pots.

How long should I grow them before planting where I want them? I saw a tree farm that grew their seeds in a piece of styrofoam with 6" deep holes cut in them. http://www.itascagreenhouse.com/treeseedlings.html

Do you think a persimmons could start well in there if planted when they get about a foot high?
Any time you can get out to hunt, is a good day to hunt.
