I have read the same thing about floating seeds. Right now I have separated the floaters from the sinkers to test this. I will plant them in separate pots to see if any of the floaters will germinate. If they don't, I will crack them open to see what is going on inside. Does anyone know how long one should allow for them to sink? I am considering them to be floaters if they haven't sunk in 3 days.

Would it be unreasonable to return floaters to the seed sellers for replacement? Recently, I got about 15 seeds and 8 of them were floaters!
I guess it depends some on what was paid for them, but I wouldn't think it was too much to ask for expensive seeds, that the seller check them in water and send only sinkers, right??? Obviously, if it is a huge seed selling operation there should be more Q.C. They usually state something like "Germination tested 90%" I am considering asking each seller to place the seeds in water and send only those that sink. Especially the seeds sold on eBay!

Brent, I hope that you didn't scarify them and put them into normal potting soil. The microbes will eat them alive. All of the research I have read on scarification indicates the use of sterile soil-less mix following seed surface sterilization and then scarification. As i recall there was 0% germination of scarified seeds in normal soil. Perhaps if you didn't nick them too deeply, you might get lucky, I hope.
