When I place them out in
the heat of the porch, it doesn't take long for tomato seeds
to begin to mold...and that's a good thing! I'll wait until the film of
fungus is a bit more intense than is shown in the photo on the right,
then I'll swish the seeds apart from their gelatinous casing. A few
days drying on a plate and the seeds will be ready to be packed away
for next year's garden.
I'm curious why is the fungi film o the seeds beneficial for them. Just some keywords so I could google for more.
Good luck with packing and moving
