In the event that your state is home to a medical cannabis program, legal adult-use weed, or both, the packaging for cannabis has seen a significant improvement in the last few years. Nowadays, weed products are likely to have a harvest time on them, but seldom does it have the date of expiration. Therefore, even with improvements in packaging however, you’ll probably be confronted with the same old question: how long will the weed last? And how can you ensure that your weed stays fresh?
This article will discuss the importance of storing your weed in a proper manner, how to ensure that your weed stays fresh, and how long it can last in optimal conditions.
Why Proper Cannabis Storage Is Important
Moisture is the most significant danger to the shelf life of cannabis. Cannabis that is too moist can be harmful to health in particular, by promoting the growth of mildew and mold. These dangers are so severe that American Society for Testing and Materials (ASTM), a body that creates standards for technical practices across many industries, issued its ” Standard Specification for Maintaining an Acceptable Water Activity (aw) The range (0.55 0.55 to 0.65) in dry cannabis Flower” on May of 2018.
The ATSM describes water activity in terms of “the (quantitative) capacity of cannabis flowers in sealed containers or a Session stash jar to influence its humidity within the container’s headspace.” Headspace refers to the air surrounding the flower. Water activity measures the vapor tension against water that is pure. If the activity of water is 0.55 or more, that is 55% water.
A relative humidity that is higher than 65% could dramatically increase the chance that your stored cannabis may develop mold. In the words of the American Herbal Products Association The drying process will cause cannabis to dehydrate till it is at a humidity level that is less than 15%. Moreover, it is during the process of curing the time when all moisture remains is gradually removed, allowing oily volatiles.
In other words, too much water is not good: but if it’s too dry, it may alter the structure of the flower. For instance, your flower may become dry or lose crucial terpenes which alter the taste and potency of your flower.
Fortunately the process of achieving the ideal balance starts long before you purchase the weed. While no cultivators dry their flowers the same manner but every cultivator dries their flowers and then runs them through a process known as curing.
If cannabis is properly dried in a controlled manner, it allows the moisture in the buds to slowly evaporate out of the flower without harming the cannabinoids and Terpenes. After the flower has reached the ideal moisture content (typically between 6 to 9 percent) It is then put into a container from which oxygen has been eliminated. When you bring the flower home, you need to ensure that you maintain that equilibrium.
Proper storage means maintaining the water activity of your cannabis within the limit that is between 0.55 to 0.65. The rate of activity in water increases with temperature. This is the reason the control of temperature and light are essential to keep your buds fresh.
The bottom message: Make sure your weed does not become too moist. I have started using a smell proof stoner backpack to keep it at hjome with no smell penetrating the surrounding area.
The ideal temperature for storing your cannabis
The ideal temperature for storing your weed is 70°F (21 degree Celsius). Why? The combination of high temperatures and relative humidity could cause mildew and mold -one of the biggest enemies of healthy and safe cannabis.
The high temperatures may make your flowers dry and cause the evaporation of sensitive terpenes, however this shouldn’t be a problem when you are planning to use an electronic flower vape that has exact temperature control. The fact is, lighting an e-cigarette with a torch will destroy the majority of them in the end.
The bottom line is: Store your weed in a cool location like a closet, or in the pantry.
