What is the Ol' Blue strain?

Ol' Blue is a indica cannabis strain with up to 24.0% THC, known for its relaxed effects and blueberry and earthy flavor profile.

Ol' Blue is a classic indica-dominant cannabis strain with a storied history in the Pacific Northwest cannabis scene. The strain's exact genetic origins remain somewhat obscure, but it is widely believed to be a phenotype of the legendary Blueberry strain that was stabilized and developed by growers in Oregon and Washington during the 1990s. The name 'Ol' Blue' reflects both its lineage and its distinctive blue-tinged appearance when grown under optimal conditions, particularly during cooler nighttime temperatures which enhance anthocyanin production in the plant.

The strain is characterized by dense, resinous buds that display a striking color palette ranging from deep forest green to violet and blue hues, often accented by vibrant orange pistils. The buds are typically compact and tightly structured, with a thick coating of trichomes that gives them a frosty, crystalline appearance. Ol' Blue has maintained a dedicated following among connoisseurs who appreciate its consistent effects and complex flavor profile, though it has become somewhat less common in commercial markets as newer hybrid strains have gained popularity.

Notable features include its distinctive aroma that combines sweet berry notes with earthy undertones, and its reputation for producing deeply relaxing effects. The strain has been preserved by several boutique growers and seed banks who value its genetic stability and historical significance in the development of West Coast cannabis culture. While not as widely available as some modern hybrids, Ol' Blue remains a sought-after strain among those familiar with its heritage and characteristic effects.

How do you grow Ol' Blue?

Ol' Blue is considered a moderate-difficulty strain to cultivate, suitable for growers with some experience. The strain has a flowering time of approximately 8-9 weeks when grown indoors, with outdoor harvests typically ready in late September to early October in northern hemisphere climates. Plants tend to be medium in height, usually reaching 3-4 feet indoors and 4-6 feet outdoors when given adequate space.

Yields are moderate, producing approximately 14-18 ounces per square meter indoors or 16-22 ounces per plant outdoors under optimal conditions. The strain performs well in both indoor and outdoor environments but thrives in controlled indoor settings where temperature can be carefully managed. Cooler nighttime temperatures (around 60-65°F) during the final weeks of flowering can enhance the development of the strain's characteristic blue and purple coloration.

Special considerations include maintaining good air circulation to prevent mold in the dense buds, and providing adequate support during late flowering as the resinous buds can become quite heavy. The strain responds well to both soil and hydroponic growing methods, though many growers prefer organic soil cultivation to enhance the terpene profile. Nutrient requirements are moderate, with some sensitivity to overfeeding, particularly during the vegetative stage.
