Ernie,

The preferred way, discussed in the archives probably under forcing,
is to store them in barely moist chick-grit, starter-grade. It's
marketed under trade names like  Granigrit, etc and is actually granite
that's been ground to a uniform size with minimum dust included.
Started-grade is just the right size for tuber storage.

Chick-grit holds just the right amount of moisture and separation is easy=when
they are to be replanted. Mostly we use labeled zip-loc baggies to hold
them, thus eliminating a mix up.

If you search the archived for Craig Stubbs, you should find the
documentation of his experiments with perlite, vermiculite, chick-grit,
etc. I believe he concluded that chick-grit was superior to all other med=ia.
Jim McClements used Turface but found it held too much moisture as did
Craig.

Hope this helps.
