• Cannabis seeds are orthodox, meaning they can be dried to low moisture contents, around 5-8%, and kept cold down to -20°C, with little loss of viability if they are quality seeds and not dormant, empty, embryo-less, insect-damaged, or even dead seeds.
• Short-term storage (up to 1 year)
-Dry the seeds with a dehumidifier to 5-8% moisture content, place them in airtight containers and store them in a place at 0-10ºC
• Medium-term storage (1-3 years)
-Dry the seeds with a dehumidifier to a moisture content of 5-8%, place them in airtight containers, and store them at 0-5°C. If the containers are not airtight, the relative humidity of the storage area should not exceed 15%.
-The average germination loss in quality seeds over 3 years is 1.10%, and the highest losses, depending on the batch, are 4.3%.
• Long-term storage (3-6 years)
-Dry the seeds with a dehumidifier to a moisture content of 5-8%, place them in airtight containers and store them in a place at -18-20ºC
-The average germination loss in quality seeds over 6 years is 1.52%, and the highest losses, depending on the batch, are 5.27%.
-In long-term storage, plants with non-hereditary abnormalities and mutations may appear, so it is likely that some selection will occur and there will be ecotypes and batches that retain their viability better than others and show heterogeneity with respect to the initial storage conditions.
