Seeds have changed....... the shells getting harder, and sometimes its tricky for the plant to get rid of the shell
some seedlings top themselves with the Shell
Solution......spray on the seedling water... give it an open dome( halved plasticbottle with little holes) and spray on the ground, so ahumid envoirement appears
that should help within 2 days.....
and if she still stucks after spraying,,, hel her alittle and very soft. to get out of the shell
