New strains are great and all, but sometimes, you want to go a little Old School. Also known as Pure Kush, this strain has OG Kush roots and a mysterious breeder. It has around 20 percent THC, making it a heavy hitter. It’s a kushy, skunky-tasting strain with thick nugs, orange hairs, and a purplish appearance. It’s covered in tons of trichomes and resin, too. For growers, this strain flowers in about 8 weeks with lots of yields, and it has mold and mildew resistance.
