Old Blue Sky
Also known as: Blue Sky OG, Old Blue
What is the Old Blue Sky strain?
Old Blue Sky is a indica cannabis strain with up to 24.0% THC, known for its relaxed effects and berry and earthy flavor profile.
Old Blue Sky is a classic indica-dominant cannabis strain that emerged in the Pacific Northwest region of the United States during the late 1990s. The strain's exact origins remain somewhat obscure, with competing claims about its development, but most sources agree it was cultivated by underground breeders in Oregon and Washington who sought to create a potent, flavorful indica with distinctive blue and purple coloration. The strain gained popularity among medical cannabis patients before becoming more widely available in recreational markets.
The strain is characterized by its dense, resinous buds that often display striking blue and purple hues, particularly when grown in cooler temperatures. These colors result from anthocyanin pigments that become more pronounced as temperatures drop during the flowering phase. The buds are typically covered in a thick layer of trichomes, giving them a frosty appearance. Old Blue Sky has a complex aroma profile that combines sweet, fruity notes with earthy undertones and a hint of pine.
Notable features of Old Blue Sky include its relatively short flowering time for an indica and its resilience to common growing issues like mold and pests. The strain has maintained a dedicated following despite the proliferation of newer hybrids, valued for its consistent effects and distinctive appearance. While not as widely cultivated commercially as some modern strains, it remains popular among home growers and connoisseurs who appreciate classic genetics.

Indoor yields typically range from 400-500 grams per square meter, while outdoor plants can produce 500-600 grams per plant under optimal conditions.
