Germinating Pelleted Seed

[JackE]

Increasingly, much of our seed is now coming in pelleted form. For some reason, these seeds don't seem to germinate as well, or as quickly, as our old unpelleted, treated seeds for the same varieties. We are using the same procedures as always - same bottom temps, same medium, moisture etc. The white coating seems to break-down almost immediately, exposing the seed to moisture -- I can't understand it.
Has anyone else noticed this?

So for we've only had two varieties come pelleted - Amelia tomatoes last year and now Revolution peppers, - from two different suppliers and both have germinated slower and at lower rates than we would expect.
