Cannabis is an extraordinary plant with its own distinct aroma and therapeutic benefits. Cannabis’ distinct scent comes from terpenes produced by its trichomes; their specific profile depends on each strain’s genetics which act as an guideline for enzymes producing these aromatic compounds – all of which influence everything from aroma to therapeutic benefits.
One of the primary causes of cannabis smelling like hay is improper curing. Proper curing requires a certain amount of time for all chlorophyll to degrade and mature while all terpenes develop and mature; to reduce this hay scent in your cannabis crop ensure it dries slowly with constant airflow and low humidity conditions.
Make sure that the buds are not packed too tightly together or resting against each other, as this could result in wet or humid spots among them, inviting mold growth and leading to that familiar musty or hay smell commonly associated with cannabis.
Aiming to avoid any unwanted hay smell in cannabis requires taking time in both drying and curing processes to allow terpenes and chlorophyll enough time to develop and degrade without impacting quality or therapeutic benefits of your buds.
