The 303 Kush strain (cultivar), also known as 303 OG Kush, is a cross between the Pre-98 Bubba Kush and Chemdawg strains. This indica-leaning hybrid comprises 60% indica and 40% sativa. Its tetrahydrocannabinol (THC) level is up to 18%, with cannabidiol (CBD) content of less than 1%. 303 Kush has been reported to have sleepy, relaxing, euphoric effects, potentially beneficial for stress, pain, insomnia, and depression.

Its breeder is officially unknown but speculated to be Zombo, a cultivator from Colorado. 303 Kush is a richly flavored smooth smoke. It has a complex flavor profile with coffee, diesel, and spicy taste undertones.

This strain is not considered difficult to grow, and both beginners and experienced cultivators can grow this strain relatively easily. The challenge comes from finding the seeds online, resulting in many growers using propagated clones.
