What is the Magnum Opus strain?
Magnum Opus is a hybrid cannabis strain with up to 29.0% THC, known for its euphoric effects and citrus and diesel flavor profile.
Magnum Opus is a legendary cannabis strain created by the renowned breeder Mandelbrot (also known as Ras Truth) from Emerald Mountain in Northern California. Originally bred by Mandelbrot, this strain represents the fusion of a highly prized 10th Generation Long-Valley Reserve Male with Mandelbrot's original Royal Kush F1 clone. The Magnum Opus serves as the end of the line for breeding Royal Kush and stands as a salute to one of the greatest breeders and visionaries in the history of the Emerald Triangle. Following Mandelbrot's tragic passing in 2015, the work was carried on further by Leo Stone and continues to be preserved by respected cultivators and seed companies.
This strain exhibits oversized flowers that are usually dark green with a mix of purple along with dark amber pistils and chunky amber trichomes, displaying dark purplish hues. Magnum Opus is genetically a cross of Sour Diesel, Garberville Purple Kush, and Highland Afghani, creating a well-balanced hybrid strain that combines the best qualities of both indica and sativa strains. Interestingly, it is actually a lower potency strain compared to modern breeding standards and often isn't sought individually, yet it maintains legendary status among connoisseurs for its unique characteristics and historical significance in cannabis culture.
