Too few measurements for a terpene ranking
Only 2 results include individual terpene measurements. They are too few to support a representative ranking.2
Leafly lists caryophyllene, limonene and myrcene in that order.5 This published description is separate from our limited lab sample; consult a batch analysis for the flower you are comparing.
Individual terpene data is available for only 2 matched tests. That is below our 50-test threshold for displaying a terpene ranking. These few samples do not establish a strain-wide profile.2
