All Pot Zero cannabis has a Use By Date of 15 months from harvest date. Shelf stability studies were recently conducted on 15 month old flower and these studies indicate that there is no appreciable potency change. In fact, the aggregate potencies went up 7.89% from the original laboratory testing. The study took three different batches from three different strains. Additionally, there were no microbes detected and water activity levels remained consistent.

The reason we get these results is that upon harvest in October our cannabis is cold dried by the naturally chilling environment at 8107 ft elevation in the Rocky Mountains. Once the flower is properly dried it is cold cured in special bags and stored in the dark and cold of our winter environment. Since the product is cryogenically preserved by Mother Nature, this minimizes degradation to the flower.

Uniquely, this standard operating procedure is free of any unnecessary energy consumption and fits the Pot Zero sustainability mission. It is the actual cold of the winter that protects the product. To keep this volume of product in an artificial environment with the same cold would cost a fortune in buildings, refrigeration, equipment, and electricity usage. At Pot Zero it is free. Additionally, we keep the product cold throughout the warmer months.

Most indoor grown marijuana is kept in hot warehouses where degradation is hastened. Additionally, the use of chemical fertilizers creates the environment for the material to break down because of potent chemicals that exist in the product. The gases from these chemicals need to escape. At Pot Zero we do not use synthetic chemicals at all.

Lastly, the other contributing factor to the preservation of our fine cannabis is our elevation of 8107 ft. Oxygen levels are substantially lower at this elevation. This low oxygen environment combined with the use of special bags and packaging enhances the longevity.
