501st OG, bred by Rare Dankness, is an indica-dominant hybrid that crosses Skywalker OG with Rare Dankness #1. The colorful flowers are tinged with a wide spectrum of green, blue, red, and purple hues that give off a deep piney kush aroma that mixes with the sweetness of grape flavors. The potent effects make 501st OG a great nighttime strain to help with pain relief and trouble sleeping.
