Hi Barb,
You have a pressure cooker you are safe; however, it's better to wait for 7 days (not 5) especially you don't have a lot of seeds and you sow the first time. One more tip, punch or drill a tiny hole on the top (1-2 mm), cover by 2 bandages (cross). When you take the jar out of the cooker close the top right away. If you don't do that when you take the jars/bottles out of the pressure cooker and let them cool the contaminate air could enter. If you close the top when it's hot the jar will be under pressure. When you open for sowing it sucks the contaminate air in. Using a hole with 2 bandages cover reduce contamination as well as avoid under or over pressure inside of jars. Remember don't close the top too tight before cook it could break your jar. Gooood luuuccck.
