Once the herb is dry, what we know as curing begins. It becomes normal that the buds that we consider dry, the day after putting them in a pot, are not so dry. This is due to the moisture that they still retain inside that is transferred to the outside. In these cases, it is convenient to remove all the buds from the pot and give them a few more hours or days to dry. Remember that humidity is a great enemy of an already dry bud, and fungi can appear. Temperature is also another factor that causes terpenes and cannabinoids to degrade more quickly. Ideally, during drying, curing and conservation, it should not exceed 25ºC. Also, above this temperature, fungi proliferate more easily. And finally, light also degrades these compounds that we want to keep intact for as long as possible. So the place to cure and preserve marijuana must be a dark place, at a temperature below 25ºC and with a humidity between 58% and 65%. Although at first, the humidity may not seem important since the buds will be in closed containers, each time we open them, they can lose moisture or gain it. And this is something that does not interest me either. A great option is to keep them in the fridge, at about 5ºC. This low temperature makes the degradation of cannabinoids and terpenes very low. But due to the high humidity inside the refrigerator, it will be necessary for the conservation containers to have perfectly airtight closures. Better containers to preserve buds Without a doubt, the best containers for storing marijuana are glass and stainless steel jars. Any of these that we have in our house can be perfectly recycled. But before putting the buds inside, it is advisable to sterilize them to eliminate any odor and bacteria. For example, do not use a jar that has contained olives without first sterilizing it. Otherwise, that bad smell will be transmitted to the buds. And I don't think anyone likes a joint with a hint of olive. The sterilization process is very simple. They can be washed in the dishwasher, but this isn't the most efficient method. It is best to boil them in water for about 10-15 minutes. If they are glass jars, put a clean cloth in the bottom of the squid. Thus, with the bubbling of the water and the movement of the boats up and down, they do not break. If they are made of stainless steel, we will not have this problem. Another option is to put them in the microwave, but only if they are made of glass. We fill them up to half with water, we put the jars in the microwave, and it is usually enough with about 3 minutes at maximum power or until the water boils. Then we remove them with the help of mittens, empty the water and put them face down on a clean cloth to dry. New containers with hermetic closures are, without a doubt, the best option. How to preserve marijuana in a vacuum You can also preserve the buds in a vacuum. This system has a great advantage: the total extraction of air from the storage container, one of the great enemies of cannabinoids. In addition, once packaged, it will take up less space than in cans. And perhaps most importantly, by extracting the air from inside the buds, oxidation and the possible proliferation of fungi are avoided. To vacuum marijuana, you will need special cannabis bags and a packaging machine. Put the buds in the bag, without filling it completely and without pressing excessively. Then use the canner according to the manufacturer's instructions to extract all the air from inside the bag. There are different types of vacuum packers. You can also do it manually, inserting a straw into the mouth of the bag. Then breathe in hard to extract as much air as possible from inside. To finish, remove the straw and close the bag quickly so that no air returns. It is not the best system, but it becomes quite effective with a little practice. Keeping buds in the freezer It's something that many growers still view with suspicion. But if any food can be frozen to last a long time without losing properties, why not do the same with marijuana buds? The ideal is to do it with the buds vacuum packed since the air and oxygen contain oxidation and the development of bacteria. Whenever you want, take the buds out of the freezer and let them thaw naturally. Avoid touching it in any case, as the trichomes will come off very easily. You will be amazed to see that they have not lost an iota of flavor, and their texture will be practically the same as before they were put in the freezer. With this system, they can last 1 to 2 years in good condition. Conclusion The conservation of the buds should start once they are dehydrated and the curing has been completed. It is worth keeping the buds in appropriate containers, with hermetic closures that prevent moisture entry from the outside. Another good option is vacuum packaging since it removes the air from the interior of the containers that cause accelerated oxidation of cannabinoids. The containers store them in a dark and cool place. The ideal is low temperatures, around 5-10ºC. If it's impossible, at least they do not exceed 25ºC.
