I dont use a paper towel i use a lil shot glass type thing and fill it with distilled water. Well not fill just enough to cover the seed, then set it on something warm and cover it so its dark. In 12 hours i check it and make sure it sinks, sometimes you gotta poke it a bit. Around the 24-48 hour mark it should be sunk and splitting then i just plop it in the soil less mix i got. If they dont sink in 48 hours then this is what most of you call a "dud" i say no such thing. Take it out let it dry a few hours, then lightly sand the outside a lil it will look like you scratch off a lil outside skin and its discolored slightly from the rest. Just a spot or 2 like that is ok throw it back in the water and it should sink this time and split ive had a 99% germ rate like this. Some seedling might not make it but all the seeds will open. The one that makes that 1% just sunk this morning so we will see if it sprouts finally. It is a pick and mix dutch passion blue chimera.
