Seed struggling to germinate

Hello. You can try a little cloning gel mixed in the water. Please look up cinnamon for plants. It has similar property's to cloning gel but is antifungal too. when starting seeds next time use filtered or distilled water. There is a fungus that's in the water that usually gets older slower seeds. Sometimes this works but you have to be careful. Open up the shell but don't take it all the way off. place it on soil or peat and 1/2 cover with the root pointed down and put it into the light. My theory is the tired old seed needs some photosynthesis to get some energy to keep growing. Sometimes it works, sometimes it doesn't. Good Luck. Chuck.
