Underlying scents of lemongrass and fruit can also be detected. Upon inhalation, the flavor profile mirrors the aroma, starting with bright citrus and lemon notes that transition to a more grounded, earthy finish, complemented by a mild herbal spice.

These effects are generally considered fast-acting and potent, contributing to its reputation for delivering a powerful, yet balanced, sativa-dominant high.

Terpenes & Cannabinoids

This strain typically contains THC levels ranging from 15% to 20%, with CBD levels below 1%.
