If you took them off the heat mat that will slow them down.

yes, I know that. But they were on for a while and should have been close to popping up when the Banana Peppers came up. Unless they are an especially slow to germinate type, which is what I'm trying to find out. Oh well, guess I'll plant another batch. I suppose it's better to have twice as many rather than none at all.

I've seen lots of differences in germination times depending on the variety of pepper. Even seeds from the same variety planted side by side sometimes germinate several days or even weeks apart. Yours may well show up yet.....or not.

Your idea to start more sounds good if you think you have waited long enough. I'd agree that too many is easier to deal with than none at all :)

Naturegirl is correct about germination times
