UW
Also known as: U-Dub, UW Purple, Black 84, UW Black, UW Hashplant
What is the UW strain?
UW is a indica cannabis strain with up to 26.0% THC, known for its relaxed effects and berry and earthy flavor profile.
UW, also known as U-Dub or UW Purple, is a legendary indica-dominant cannabis strain that carries a mysterious and intriguing origin story. Popular rumor has it that a clone was stolen from a certain Pacific Northwest university's medical research lab in the early nineties—in some versions by a rogue graduate student—and has since been a popular top-shelf indica. The most common hypothesis positions UW as an indica-dominant line with Afghani ancestry, potentially connected to older Pacific Northwest staples like Northern Lights. The exact genetic lineage of UW remains uncertain due to its clandestine origins. However, it is widely speculated to be a pure indica or an indica-dominant hybrid, likely deriving from Afghan landrace strains.
UW is characterized by its distinctive appearance and potent effects. UW boasts large, eye-catching flowers that are spherical in shape. These buds have the dense, heavy structure that marks other pure indica varieties. The tightly-coiled leaves are almost equal parts green and vivid purple and are threaded through with copper-colored pistils. The best UW cuts tend to sparkle with dense trichomes and lean toward sweet berry and grape notes layered over earth and pine. Any purple in the leaves is due to a high genetic concentration of anthocyanins—pigments like chlorophyll that, when stimulated by cold weather in the growing process, bring out the purple coloration. Unlike strains released with breeder catalogs, UW emerged from a tight local network and spread by clone swaps rather than formal seed drops. Seattle's cannabis scene has long been known for resinous flowers and dessert-like aromas, a regional style that matches what many users report from UW.

How do you grow UW?
UW plants are easy to cultivate as long as they are topped regularly and make sure that they get enough sunlight and moisture, especially when flowering. This strain can grow into a medium sized plant and can yield quite generously when kept in its ideal growing environment. UW grown indoors can be expected to yield an average of about 12 ounces of bud per square meter of plant, and takes an average of about 8 to 9 weeks to fully flower and be ready for a harvest. UW flowers within a short 7 to 8 weeks when grown indoors. Uw flowers in 56 to 63 days indoors and by mid-October outside. UW can be successfully grown indoors or out, although outdoor growing requires warm, Mediterranean-like climates with daytime temperature in the 70 degree Fahrenheit range. Plants are short and bushy, with strong lateral branches. Growers should be sure to 'top' their plants by regularly trimming away large fan leaves that might block light and air from reaching low-growing flowering nodes. Growers looking to bring out this strain's full purple potential should also shock the plants by exposing them to cold (but not freezing) nighttime temperatures late in the vegetative stage. Seeds are not commercially available; prospective growers must obtain clippings from mature plants to grow as identical 'clones.'
