Drying seeds at 10 – 25 degrees Celsius (50 – 77 degrees
Fahrenheit) and at 10 – 20 % relative humidity using either
some type of desiccant (silica gel or activated alumina) or a
dehumidified drying chamber (set at the lowest heat setting
or no the “no heat” setting) is ideal but air drying is common
as well. Desiccants should be replaced every 3 to 5 years
and dehumidifiers should be carefully watched so that seeds
are not damaged by the heat
