P91
Also known as: P-91, Project 91
P91 Strain Overview
P91 is a legendary cannabis strain with origins tracing back to the 1990s in Southern California. The strain was reportedly developed by a breeder known as 'The Chemist' who worked with a collective of growers to create this potent hybrid. The name 'P91' stands for 'Project 91,' referencing the year 1991 when the breeding project began, though some sources suggest the 'P' may stand for 'Pure' or refer to a particular phenotype selection process. The strain gained notoriety in the medical cannabis community during the late 1990s and early 2000s for its consistent quality and powerful effects.
P91 plants typically display dense, resinous buds with a distinctive appearance featuring dark green foliage often accented with purple hues and vibrant orange pistils. The buds are known for their exceptional trichome coverage, giving them a frosty, crystalline appearance. The strain's aroma is complex and pungent, combining earthy, diesel-like notes with subtle hints of citrus and pine. When properly cured, P91 produces thick, expansive smoke that many users describe as smooth despite its potency.
This strain has maintained a cult following among cannabis connoisseurs despite not achieving widespread commercial distribution. P91 is particularly noted for its balanced effects that combine cerebral stimulation with physical relaxation, making it suitable for various times of day. The strain's genetics have influenced numerous other popular hybrids, though the original P91 remains relatively rare outside of certain West Coast cannabis circles. Its reputation for consistency and potency has made it a benchmark against which other hybrids are sometimes measured.

P91 Strain Growing Information
P91 is considered a moderate-difficulty strain to cultivate, best suited for experienced growers. The plants typically flower in 8-10 weeks indoors and are ready for outdoor harvest in late September to early October in the Northern Hemisphere. Indoor yields are generally moderate to high, producing approximately 400-500 grams per square meter under optimal conditions. Outdoor plants can yield 500-600 grams per plant in favorable climates.
The strain prefers a Mediterranean-like climate with consistent temperatures and low humidity during flowering to prevent mold issues. P91 plants tend to be medium in height, reaching 3-5 feet indoors and 5-7 feet outdoors. They respond well to training techniques like topping and low-stress training to maximize yields. The plants require good air circulation and benefit from regular pruning to ensure light penetration to lower bud sites. Nutrient requirements are moderate, but the strain is sensitive to overfeeding, particularly during the flowering phase.
