We are looking for information on the best methods to ship plant seeds
around the US to avoid temperature extremes (anything above 95 and
below 32 degrees) and high humidity that would decrease the
germination percentage of the seeds.  Please include not only shipping
protocols (refrigeration, air vs. ground etc) but also packaging
strategies that could assist in maintaining seed germination
percentages.  The seeds will be embedded in peat grow plugs and then
the plugs will be placed inside a paperboard box.  This is a retail
product so the look of the package must be considered when weighing
packaging options.
