Tatsuo,
yes of the petticoat Narcissus are going over but N. cantabricus forms are just emerging and N. triandrus is a while away from flowering so a few more of these beauties will appear in coming weeks. The trumpet Narcissus are coming out big time in the bulb houses now.
With the soaked seed I showed in the small round bottle tops I just tip the entire contents into the pot. As Matt says there is such a tiny amount of detergent there that it will not cause a problem even if it is harmful to plants.
I also use plastic packets for some seeds - I attach a picture comparing two packets of Eryhtronium seeds, one soaked the other not, to show what a difference an overnight soak can make to the seeds.
I have never tried keeping the soaked seed in a fridge basically because they will get more exposure to cold outside in our garden. I can understand in warmer areas it could provide and advantage to speeding up germination in plants that require a number of cold periods.
Matt I have also used the glassiline packets as you describe with the same fiddly problem of extracting the seed. I suppose we could just plant the whole packet and let nature break it down but that could just defeat the object of speeding up and improving the germination rate of stored bulb seeds
There is an interesting topic been started here
http://www.srgc.net/forum/index.php?topic=11481.0 that also discusses this subject and puts the view that soaking like this can harm the seed that you should also read. It may make sense to merge these two topics if this discussion continues.
