I have germinated them before (then killed them later
).
Nowadays when I use peat moss I wet it down in a glass bowl then cook it in the microwave. This takes care of gnats or gnat eggs that seem to be carried in peat mixes. Try this.
Then to germinate, I did it at around 60 deg. Warmer than Western Americans but not real warm.
Maybe you got bad seeds. You don't really know what you are getting from NALS since they are all donated from volunteers. If you can grow your own parent bulbs you will know your seeds are fresh.
