This isn’t the same pepper where the seeds in the Petri dish came from. The seeds in the petri dish did come from a store-bought pepper though. If you zoom in you can see some of them have germinated. I’ll give them a couple more days before I plant them in soil.
Removing the seeds is simple. Of course, you have to cut the pepper open, scrape off the seeds onto a paper towel. Allow the seeds to dry in the open air and store them in a dry place if you don’t plan on planting them right away.
