Sometimes a strain can bie successfully crossed with itself -- although it may sound counterintuitive, the exchange of traits from markedly different phenotypes of a single variety can yield amazing results. P-91 is a great example of this experimental breeding: it is the product of a Northern Lights female crossed with a Northern Lights male, and then back-crossed a third time with the original Northern Lights mother plant. There is also some conjecture that P-91 may in fact be the child of a Skunk #1 female and a Thai landrace male.
 
Whatever its genetic background, though, cannabis breeders generally agree that this strain originated in Poway, a town in San Diego County, California in 1991 (hence its name). P-91 is a stable and potent strain that shows off all the qualities that made Northern Lights famous: strong and long-lasting indica relaxation alongside a buzzy sativa edge. Cannabis testing lab Analytical 360 clocks its THC content at an impressive 20%.
 
Flowers of P-91 appear small to medium in size and hold a dense, indica-typical formation, with particularly wide leaves coiled around their stems. The vibrant green leaves are threaded through with orange to brown pistils. Amber trichomes cover the buds, giving them a slightly yellow tint and an incredibly sticky texture -- this is one strain that’s very hard to break up without the use of a grinder. At first, users are struck by the flowers’ bright citrus scent. On closer inspection, there’s also a slightly astringent tang, reminiscent of ammonia cleaning products. Breaking open the buds yields more spicy notes, presumably inherited from grandparent strain Afghani. When combusted, P-91 gives off a harsh, acrid smoke that may sting eyes and sinuses and induce coughing. On the exhale, it tastes sweet and lemony with some traces of damp earth.
 
P-91 takes effect quickly, beginning as a pressure around the eyes and temples. Smokers may soon perceive external stimuli more intensely than before -- certain colors or sounds may take on an entirely new dimension. A while later, after they have adjusted to their altered states, this head buzz melts into a stoney body high. Worries and muscular tension both dissipate as relaxed smokers sink into the closest comfortable surroundings. P-91 still keeps its fans lucid, though, and while it may not be the best strain for productivity and problem-solving, it’s great for creative thinking. It can also be a good way to enhance appreciation of psychedelic music and art. As this high wears on, couchlock may set in, providing the perfect setting for thoughts to wander or for stimulating conversation to flow.
