storage of dried cannabis flowers:
Cannabis products are organic products, among other things, by their molecular compositions such as cannabinoids (CBD, THC, CBG, CBN…) or terpenes (a-pinene, limonene, myrcene…). As a result, these products are “living” and evolve according to the environment in which they are stored.
How best to preserve dried CBD flowers?
Proper storage and care of cannabinoid and terpene products is important to maintain their potency and freshness, by methods that minimize their inevitable degradation.
The methods for properly conserving these dried cannabis smugglers are not especially complex, it is especially important to limit their exposure to certain elements such as humidity, heat, extreme cold and light.
The shelf life of cannabinoid and terpene products varies greatly depending on these conditions. Depending on where you keep your CBD flowers, CBD flowers can strongly influence their effectiveness over time, from a few seconds for extreme conditions to a few months for ambient conditions. However, these dried flowers can retain their potency and therefore their effectiveness for months or even years undergoing almost no degradation if they are kept in an optimal environment (2).
According to studies, however, cannabinoids and terpenes degrade relatively slowly at room temperature (22°C) compared to a refrigerated temperature (4°C) where it could be thought that preservation remains better. This is the case, but temperature differences are also important. We will conclude with these data that the environment will depend on how long the product is expected to be used (1), (2), (3).
For a fast use of dried flowers of the order of 1 to 6 months, an ambient temperature of 20-25°C is sufficient and it will not be desirable that the products are refrigerated (4°C), because:
For this period there is a decrease in the rate of cannabinoids of less than 10%, which does not have too much impact on the potency of the product.
The many temperature variations to which products are subjected when alternating between refrigeration and the outdoors can accelerate their degradation compared to an ambient stability such as a closet in a well insulated room.
On the other hand, if these CBD dried flowers will be used only infrequently, with a long and irregular use projection of more than 6 months, their conservation will preferably be refrigerated at 3-5°C, because after 6 months, one will have a degradation in a non-negligible ambient environment and, because of a less frequent use, a lower risk of degradation related to the thermal differences (1), (3).
fast use from 1 to 6 months: dark place, room temperature (20-25°C)
prolonged use for more than 6 months: Dark place, chilled temperature (3-5°C)
It is also important to respect the expiry date of the product, in order to guarantee total effectiveness.
For dried cannabis flowers, three rules are essential:
Keep your flowers in a dark, cool and dry place.
The most important thing for dried cannabis flowers is to keep them in the darkest possible place, cool and dry.
Light degrades trichomes and alters terpenes, so keep your products as far away from direct light as possible (2).
Heat combined with high humidity, as well as thermal variations, also degrade cannabis flowers, which can cause mould and mildew, which can be dangerous to consume. Avoid storing your dried flowers near heat-producing appliances or in damp places such as bathrooms.
A relative air humidity of 60-65% is ideal for conservation. Different container systems adapted to this need are available on the market and can be a good way to have this ideal rate.
A common mistake is to store flowers in the freezer. Extreme cold temperatures will make the glands loaded with trichomas fragile to detachment and there is a risk of the active substances being found in dust at the bottom of the container. In addition, the cold can suck in moisture from flowers, breaking the resinous glands. Moon Moreover, storage at very low temperature (-18°) is not necessary for a period of less than 2 years (2).
Store your flowers in a waterproof container.
The air degrades the cannabinoids and terpenes, and in the case of dried flowers it will directly affect its power, aromas and fragrance. Flowers left outside will dry completely in a few days. The ideal container for these cannabis flowers is as dark as possible, made of glass, plastic or metal and fitted with a sealing system with a suitable seal and hermetic seal (1), (2).
Some people keep their flowers in plastic bags, risking the crushing of heads when they are handled and, under electrostatic action, the loss of trichomes, due to plastic that attracts the resinous glands of flowers.
Avoid unnecessary handling of your dried flowers:
Avoid opening containers and handling flowers unnecessarily.
If you have a large stock, the basic idea is that you have a smaller container next to it, so that you can access a certain quantity without having to handle the whole stock at every need.
Generally speaking, any unnecessary handling, whether it is an unnecessary shaking or opening of the jar, will be detrimental to dried flowers. Thus, each time the jar is shaken, a few trichomes are detached and each time a head is crushed between its fingers to release the perfume, for example, the head is degraded, the perfume that volatilizes being a phenomenon of this degradation. In addition, since the trichomes are sticky, each time they are handled, they are likely to be transferred to your fingers or other (2).
Another important factor:
Store your cannabis products out of the reach of children or pets, for example, in a place where they do not have access to them, preventing them from falling and breaking the container.
