i always stick them in the fridge for a couple days at least and then start germination, some strains wont pop unless they think winter has happened, some breeders do this before releasing them, some ship em out, but my method is to collect the seeds dry them for a good week minimum i prefer a month then the fridge i like to do that a week at least too, again i prefer a month, let them reach room temp if the shell seems to be very strong and thick i roll up a tube of sandpaper and drop them in and shake a min or 2 to scratch the shell to allow water to penetrate easier i never soak them in water i think its to easy to drown them, i put them in a root plug or paper towel method i usually get 100 percent popage !
then if the shell does not fall off i mist and remove it, some say not to but i have lost to many cuz the "helmet" didnt fall off and never saw it harm them, oh and i use superthrive in the water thats pretty much it, i never keep them in the freezer either
