I would try this. Dry the seeds out as best you can. get some of those silica gel things and put them with your seeds in a warm place, for a while. Changing the silica every few days. Then try to sprout them again, in soil or rock wool. Maybe the dry will reset them. Some other type of seeds do better if you weather them before use.

The chance this will work is low but what else can you do.
SheCutEmDown Reviewed by SheCutEmDown on . seed problems In October I purchased seeds from seed boutique. Those I planted then all popped fine. The remaining seeds were stored in the envelope in an office drawer. Now, all the seeds that I've tried to germinate February/ March have done nothing. I had them soaking in water for weeks in a warm area, I ended up putting some in grow plugs..nothing has helped. Is there a more advanced and creative try for this point in the game where I've pretty much given up on them? Rating: 5
