The Storage Phase: Where To Store Hemp

Where To Store Hemp

Failure to properly store hemp can lead to a moldy and mildewy product that won't sell in the marketplace. Furthermore, storing hemp with optimal conditions will help prevent the degradation of CBD potency within the biomass and flower. You can only fight this challenge for so long, though, as raw material will eventually lose it's cannabinoid potency if it sits for too long (even in the best conditions). It is said that degradation can occur between 6 to 12 months post-harvest with an estimated 10-15% reduction of CBD percentage.

Hemp should be stored in a different facility than that in which it is dried since cleaning is also done in the drying facility. Hemp coming into the storage facility should be through with all preliminary preparations and ready to be “left alone,” requiring no further operations than general maintenance. Maintenance operations include ongoing aeration and moisture monitoring. Both operations can be performed in either of the following facility types:


Traditional Storage Barns

Traditional barns are useful for storing plants when compartmentalization is needed. For example, some plants need to be stored whole while others are to be stored in bales. This may be the case in a dual harvest situation where both biomass and flowers are destined for the marketplace.  If using a traditional barn, it is important that it is capable of having the proper aeration standards.

Large Storage Containers

These containers are ideal for single-state storage situations.  That is, when all hemp is to be stored the same way. They are especially useful when all of the plants are to be rack-hung for long-term aeration. 


In practice, both of these facility types offer little qualitative distinction resulting in one being more favorable to the other. However, the interior geometry of the selected space, along with the materials of which it is composed, will inform the types of maintenance systems that work best for a given storage space.

That is to say, moisture will behave differently inside a structure made primarily out of plastic (e.g., a shipping container) than it will inside a composite wood/metal structure (as with traditional barns).
