Marijuana growers have always faced challenges when it comes to drying and preserving their flowers. Traditionally, the method of hanging plants to dry has been the most common. While this method has been effective to some extent, it presents significant challenges. Not only do you have to worry about factors such as mold and rot if the plants are not hung properly, but the curing process can take up to eight weeks to maximize quality. In addition, this method requires considerable space, which is a luxury that not all growers can afford.

It is in this context that freeze-drying, using devices such as those from Harvest Right, has emerged as a promising alternative. This method reduces drying time to just one or two days and is much more space efficient. It also preserves the plant’s characteristics almost intact, from its freshness and appearance to its cannabinoid content and therapeutic efficacy.

What is freeze-drying and why is it revolutionary?

Freeze-drying is a preservation method that has been used in the food and pharmaceutical industry for years. Also known as freeze-drying, this process involves freezing the product and then dehydrating it in a vacuum chamber, allowing the water to pass from a solid state to vapor without passing through the liquid state. In the case of cannabis, this method is particularly effective in preserving the potency and terpene profile of the plant.

This process is not only effective in prolonging the shelf life of foods and medicines, but has also been shown to be very effective in the preservation of herbs such as marijuana. Freeze-drying is carried out in three stages: freezing, primary drying (sublimation) and secondary drying (desorption). The result is a stable product that does not require refrigeration and can last up to 25 years under proper conditions.

Advantages and disadvantages of freeze-drying for cannabis

Freeze-drying cannabis presents a unique set of advantages and challenges that every grower should consider before deciding if this is the right preservation method for their product.
