I have no tips on germinating those two types of seed. But I did see something......

Maybe these seeds are specifically different from all others, but it's the opposite of what you typed. Floaters are non-viable seeds, and sinkers are keepers. When I soak seeds this way I give them a few hours, generally overnight, and then I poke the floaters to see if any of them absorbed enough water to sink. But, granted, I don't know if the floaters that end up sinking after soaking overnight are any good.?
