What did you put in the jar besides the seeds? How long you keep them like that and what do you do after that. I will not even tell you my technique
Only thing I add is a little water. I watch it ferment a couple of days and then start shaking the jars a couple times each day. The seed will begin to drop to the bottom as they separate from the gel.
I pour off all the water and gunk that I can and pour the seeds into a strainer. I run water on the strainer to run off all the gunk I can. Then I place the seed on a paper plate to begin drying.
Each day I will fuss over them a bit with a spoon or knife, separating the seeds as best I can.
Once dry they go into a zip lock bag and into the frig.
I will test germination on a couple seeds from each batch.
