ekkoz897answered grow question 2 years ago That has happened to me once, just wait it out, the shell will split and it should grow from there.
It will just take a bit longer to get started.
The shell of the seed sometimes sticks to the seedling, which is not unusual. It often falls off on its own after a few days.
If it doesn't, you can gently try to remove it, but be careful not to damage the seedling.
Also, Ensure the seedling is getting enough light.
Good luck !
