Hi James, thank you for this page of valuable information. One little comment: You recommend blue silica gel to dry pollen. this uses Cobalt(II) chloride as humidity indicator, which was identified as highly carcinogenic in recent years. It (hopefully) should be difficult to obtain now and I strongly recommend anyone to give any remaining leftovers of blue silica gel to a professional disposal service, as there are several non-toxic alternatives. -- Martin ---------------------------------------------- Southern Germany Likely zone 7a Am 13.05.2016 um 18:44 schrieb James SHIELDS: > I put this page together years back on storing pollen: > > http://www.shieldsgardens.com/info/Pollen.html > > -- Jim > > On Fri, May 13, 2016 at 12:33 PM, Michael Mace <michaelcmace@gmail.com> > wrote:
