Jack Frost is a potent sativa-dominant strain that took breeder Goldenseed five years to perfect. Genetics of White Widow, Northern Lights and Jack Herer come together in this strain, which now also features Rainbow Kashmiri genetics. The buds are fuzzy with trichomes and emerald green in color, with abundant orange hairs and sugary crystals. Lemon notes dominate the gentle aroma and flavor of Jack Frost, which boasts THC levels up to 22 percent. Jack Frost may help alleviate depression, fatigue, migraines and related conditions. Due to its predominantly sativa characteristics, this hybrid is recommended for daytime use.
