K.C. 39® is a hybrid cannabis strain created by Spanish seed selectors and K.C. Brains. It was developed by crossing potent Spanish seeds with K.C. 606. This strain is suitable for both indoor and outdoor cultivation. The plants are mostly indica and produce dark green, bushy foliage under optimal conditions. Outdoor plants can reach heights of 2-3 meters, while indoor varieties remain short, not exceeding 120 cm.
K.C. 39® cannabis seeds have a strong genetic history and are highly resistant to pests, mushrooms, and diseases. Their easy growing nature makes them ideal for beginners. When grown indoors, the plants perform well in pots and soil. Outdoor cultivation requires finding a safe location with good midday sun and overcoming challenges such as sun-baked clay soil.
Regardless of the growing conditions, K.C. 39® consistently produces great results. Outdoor plants can yield up to 1000 grams per plant, with harvest starting in late September and continuing through October. Indoor plants yield around 200 grams per plant. This strain is known for its high yield, making it one of the best among all known marijuana strains.
Indica strains of medical marijuana typically have faster growth compared to sativa strains. The flowering period of K.C. 39® lasts just 7-9 weeks indoors and up to 11 weeks outdoors. During this time, a pleasant citrus-hash fragrance fills the air. Fully mature buds have a strong smell, are large and sturdy, and covered in white, sticky THC-rich hairs.
K.C. 39® marijuana is considered one of the strongest strains, with a THC content as high as 20%. When used for medicinal purposes, the indica plants produce medicine with higher CBD and lower THC levels, resulting in a heavier, relaxing effect.
