Does it begin with soaking it for 24 hrs?
if you want help germing and growing, id be happy to tell you how i germ.
Not trying to be a dick, but you know how it looks when someone signs up, has 0 credability and 1 post and starts talking shit cuz there 1 seed didn't pop. There is such things as duds. But most likely you drowned it. Oxygen deprived roots turn black and die. Excess water deprives oxygen. You drowned them.
Not 1 breeder I have ordered from has used dessicant packs.
I have a near 100% germ rate. Only dud seeds, or drowning a seed that is so fresh it didn't need to be soaked. To stop that, check every 6 hrs, when the seed cracks and water enters the seed sinks. When it sinks, move it to a paper towel
