The best way to store seeds for a long time is to keep them somewhere where moisture levels are going to remain constant.
Silica Gel can help to reduce moisture levels to protect seeds against the risk of germination but most containers kept inside fridges or freezers, that are regularly opened, will be susceptible to minor changes in humidity.
Aluminium Zip-Lock Bags offer the best protection from any changes in moisture levels within a fridge or freezer. The bags offer the best protection for seeds to ensure that they remain dormant whilst you store them during cannabis cultivation prohibition. They are preferable, for long-term preservation, to many of the breeders packaging in which we sell the seeds.
