FastFerment, harvest yeat

[redwing_al]

Has anyone yet harvested yeast from the new FastFerment conicals? Just wondering if I should use the slurry from the first bottle change or the second? Both bottles are loaded up pretty good with slurry, so I'm not sure which one to cap and reuse.

thanks!

Just finished fermenting our Belgian Dubbel - saved the ball with all the sludge. But how do you harvest the yeast from it? Can't seem to find any instructions on what to do after saving the ball... any help is appreciated.
