An average time for watermelon seeds to germinate is 3 days at 90 degrees F, and 10 days at 70 degrees F.
Make sure you are using a light soilless mix for seed germinating.
Sometimes, for unknown reasons seeds to not germinate. Seed packets often have germination rates on the package.
I would suggest starting some more seeds, but you can keep the pots to see if anything does germinate.
