3X Crazy, also known as Insane OG or Optimus Prime, is a three-way cross of OG Kush, Bubba Kush, and Granddaddy Purple. This strain is said to carry an aroma of grapes and pepper with earthy undertones. Insane OG is the name Dr. Greenthumb, a Caifornia dispensary launched by Cypress Hill rapper B-Real, gave its version of 3X Crazy. Pacific Seed Bank said the strain has 21% THC, low CBD, and an herbal, sweet, peppery flavor profile. 3X Crazy is an indica-leaning hybrid that does best with an experienced grower. It has an average yield and flowers in seven to nine weeks indoors or outdoors.
