I wouldn't soak the seeds long in water like some have suggested. By the time they take the soaked seeds out of the water I'd have plants popping up (superhots excluded). I just soak em for 8 hours then I put them in a humid environment. Putting them in water might even be pointless. The seeds should get wet enough in a nice hot humid environment. I have germinated seeds that float, so that's a myth. I'm not sure why they float. Maybe from having small air pockets?
