My commercial grades from OP on down swim like a fish before saying hi
to their maker. I noticed about half of my estate grades sink like a
rock while the others will matte and slowly sink to their final
resting place. For the ones that don't indicate any agony I wonder if
that is normal? I'm thinking withering and oxidation may effect the
dance otherwise any leaf will float. I recently switched back to a
see through pot and wanted to make sure the phenomenon wasn't
isolated. I even exposed some of my best swimmers to light and air
for staleness and it didn't make any difference. Any ideas?

Thanks,
Jim
