I soaked my seeds for about 4 hours until most of them sank to the bottom. I read that they should sink on one of the forums if they are viable. Not sure how accurate that is. My seeds are also in a humidity dome with a heat mat. Temp in the dome is just under 90 degrees. Seeds are just barely covered by soil as is my understanding the best way to plant these.
Hopefully you will have a few more sprout in the next few days.
