K-13 by Philosopher Seeds
Haze genetics × Fast-flowering partner
K-13, also known as K-13 Haze or Easy Haze, is a sativa-leaning hybrid developed by Philosopher Seeds. This strain offers a brighter Haze experience with more manageable cultivation traits, making it a popular choice for its energetic effects and clean flavor profile.
Appearance
K-13 typically produces medium-sized, elongated, lanceolate flowers that resemble spears. While some slight foxtailing may occur, the buds are generally more compact than those of pure Haze varieties. The flowers are often lime to mid-green, sometimes displaying a lavender hue in cooler temperatures, and are coated in a frosty layer of trichomes. Slender, serrated leaves with moderate internodal spacing are characteristic of its sativa heritage.
Aroma and Flavor
The aroma of K-13 is bright and layered, often starting with citrus zest and sweet herbal notes, complemented by undertones of cedar or sandalwood. Breaking apart the buds releases amplified citrus scents, with hints of lime and sweet orange peel, sometimes accompanied by a green tea or cut grass aroma. The flavor profile mirrors the aroma, featuring a lively citrus backbone with lemon-lime notes, supported by gentle sweetness, fresh herbs, and a subtle spicy or tea-like astringency. A clean, resinous wood note, similar to cedar, can also be detected.
Effects
K-13 is recognized for its lively, daytime-friendly effects, providing an energetic and uplifting character. It is often described as promoting creativity and offering a clear-headed experience. These stimulating qualities make it suitable for users seeking a boost without significant sedation.
Terpenes and Cannabinoids
While specific terpene profiles can vary, K-13 is generally associated with a mix that includes myrcene, limonene, caryophyllene, linalool, pinene, terpinolene, and ocimene, contributing to its bright, herbal, and citric aroma and flavor. Lab-tested potency typically falls within the 16–22% THC range, with CBD levels usually below 1%. Minor cannabinoids may also be present in trace amounts.
Cultivation
Developed by Philosopher Seeds for easier cultivation, K-13 is considered a manageable Haze-type strain. It finishes flowering faster than many traditional Hazes, typically within 9–10 weeks. Indoor yields can range from 450–600 g/m², while outdoor plants may yield over 500 g per plant under favorable conditions. Its structure is described as sativa-dominant with cooperative branching, making it suitable for indoor growing environments.
Origins and Lineage
K-13 is a creation of Philosopher Seeds, a Spanish breeder known for developing flavorful and easy-to-grow hybrids. It is understood to be a sativa-dominant hybrid, blending classic Haze genetics with a faster-flowering, more compact partner to improve cultivation traits and reduce flowering time. The strain is sometimes referred to as K-13 Haze or Easy Haze, highlighting its lineage and approachability.
