Green Crack Marijuana strain has a classically indica bud structure, with dense buds that are more small and clustered than chunky. The leaves are pale green to yellow, although the pigments in some phenotypes can cause some leaves to be streaked with purple when plants are exposed to cold during the growing process. Rust-colored pistils stand out against the colorful flowers. The buds are also coated in milky-white trichomes, giving them a sticky texture and a glistening appearance.

This visual appeal is matched by a dynamic scent. Cured properly, the flowers have a bright citrus scent with mellow undertones of earthiness and wood. The smoke is very smooth, and leaves a tang at the top of the palate and the back of the tongue, reminiscent of mango. On the exhale, smoke tastes vaguely hashy and spicy, perhaps evidence of Afghani in its lineage.
