Platinum OG is just as precious as the metal itâ€™s named after. With a THC content regularly topping 20%, this indica-dominant hybrid asserts itself as one of the â€œheaviestâ€ strains around. Platinum OG is purported to stem from three strains: Master Kush, OG Kush, and a third unknown parent. Flowers are lime green and plump, with prominent orange hairs and an appropriate platinum coating thanks to the abundance of THC crystals. A brief, heady onset settles into a powerful physical sedation suitable for nighttime use and pain, stress, or anxiety relief, making this precious strain a robust healer.
