There are all sorts of tricks to get seeds to germinate, putting them in a cup of water till they crack, wrapping them in a wet paper towel, etc. I have always had success with just treating them like any other seed, that is I put them in the growing medium (rockwool or some soil) keep them moist and let mother nature take its course.
If really nothing works, maybe your seeds are dead.
hey i had the same deal happen to me, for 2 weeks i had 2 seeds in the paper towl, kept moist, with 2 soucers, in the hotwater cupboard. like i said 2 weeks and nothing happened, so i got pissed off, and threw them in a little cup of water, and on day 2 (something cool happened i dont know what you call it) it germanated, and planted them and it's been 3 months and nothin happened. Yep BIG FAT WASTE of time, so now i brought a guitar and now waiting for a seed to pops up in my tennie when i go to score.
Sometimes the skins on seeds can be very tough and the little guys can't pop out. I read in a Jorge Cervantes book about putting your seeds in a matchbox with an emery board (fingernail file) and shaking them for about 30 seconds. I have had much greater success germinating seeds since I have been doing this. BTW, the cheap wooden files are the best as they come in packs of ten or some such.
I rubbed the edges off my seeds (gently ) with a nail file and then put them into some tissue paper and soaked them on a plate with lid (plate ).. then put them on a set top box to help keep them warm ! and NEVER let them DRY out ! seems to work fine 2-3 days ...Butta Bing Butta Bam ! Take care !
