I am trying to test the germination rate of several kinds of seeds which
I harvested within the last 60 days. Seeds were taken from various
plants when thoroughly dry. Each sample of ten seeds was rolled up in
paper towel stock and lightly wet with tap water. Each rolled up packet
was then placed in a clear plastic sealed bag and placed on a heating
pad. The pad temperature is about 90f. The seeds are Marigold, Black Eye
Susan, Coreopsis, Heliopsis and Shasta daisy.

After ten days none of the seeds have germinated.

Any ideas about what I am doing wrong?

Thanks,
