An additional cannabis strain called Rainbow Kashmiri (Rainbow Kush) is also sometimes included in the mix, but this is less common.

The sweet, woody, skunky, and citrus flavor profile contributes to the creativity-boosting, happy and energizing body effects of Jack Frost. This makes a cultivar like Jack Frost potentially helpful in managing anxiety, depression, stress, and chronic fatigue.

Jack Frost was developed and perfected by the Californian brand Goldenseed over five years. It is a sativa-dominant strain, containing 65% Cannabis sativa and 35% Cannabis indica genetics.

Jack Frost is named after the crystallized layers of frosty-looking white trichomes present on the buds of the plant. Some say they resemble Christmas trees, and bright orange pistils also characterize the plant. Overall, Jack Frost has a fluffy, dry, and delicate appearance.
