I discovered a ripe seed on one of my moms and after inspection, found another 50 or 60 more.
I left them on a shelf overnight and will put some on to soak today for the 87.5% generation. I’m planning a five gallon with many Double Grape moms and another 5 with many DG-75 (75%) dads. I’ll also be planting a few DG-75 moms for harvest to see how the project is going - those will probably be in #3s.
There are still a shitload of seeds left to harvest on the plants.
