Strain Description:

KC 45 is built to thrive in unpredictable environments. Thanks to its ruderalis genetics, this strain flowers automatically after a short vegetative phase, regardless of light cycles. Outdoors, it grows into a tall, Christmas tree-shaped plant with long, bare branches that support meter-long, cylindrical colas. The buds are slender but densely packed with resin, making them ideal for both personal use and extraction. Indoors, the plant remains smaller but still produces substantial yields. The high is fast-acting and potent, combining the uplifting euphoria of sativa with a mellowing calm from its ruderalis background—great for focus, light activity, or social sessions.

Growing Information:

Best suited for outdoor growing, KC 45 handles cooler climates and inconsistent light conditions with ease. Its autoflowering nature means you don’t need to worry about seasonal light shifts. Outdoors, it can reach 2 metres tall and deliver up to 900 grams per plant by mid-September. Indoors, it stays under 1.1 metres, producing up to 180 grams per plant with a flowering time of 8–10 weeks. For optimal results, KC 45 prefers organic soil and steady sunlight, but it also performs well in more challenging, cloudy environments—making it an ideal choice for growers in temperate zones.

Strain Flavour and Aromas:

KC 45 emits a strong lemon fragrance, particularly when the buds are disturbed. The flavour is citrusy and refreshing, with a zesty lemon hit followed by a subtle earthiness that makes for a smooth and enjoyable smoke. It’s both invigorating and clean on the palate, enhancing the overall uplifting experience.

---

Strain Lineage:

KC 45 combines Russian ruderalis—famed for its autoflowering trait and rugged adaptability—with a Brazilian sativa known for its energetic high and elongated bud structure. The result is a strain that grows with minimal intervention and produces rewarding, cerebral effects.

---

Strain Summary:

KC 45 is an autoflowering powerhouse built for resilience, performance, and uplifting results. It delivers a lemon-fresh, energetic high that’s great for daytime use, without the edge of a pure sativa. With impressive yields, strong structure, and adaptability to variable climates, it’s ideal for outdoor growers or those seeking an easy, rewarding strain. Whether you're a new cultivator or a seasoned outdoor grower, KC 45 offers a solid, stress-free grow with top-tier results.
