What is the Old School strain?

Old School is a indica cannabis strain with up to 24.0% THC, known for its relaxed effects and earthy and hash flavor profile.

Old School is a classic indica-dominant cannabis strain that represents a throwback to traditional cannabis genetics from the 1980s and 1990s. The strain's exact origins are somewhat debated among cannabis historians, but most sources agree it emerged from the West Coast cannabis scene, likely as a phenotype selection from older OG Kush or Afghani landrace genetics. Breeders sought to preserve the robust, resinous characteristics of pre-commercial cannabis varieties before the proliferation of modern hybrid breeding practices.

The strain exhibits classic indica morphology with dense, compact buds that form in tight, chunky colas. The flowers are typically dark green with occasional purple hues that emerge under cooler temperatures, covered in a thick layer of milky trichomes and vibrant orange pistils. Old School's aroma profile is distinctly earthy and pungent, reminiscent of the cannabis varieties available before the widespread introduction of fruity and dessert-like terpene profiles that dominate contemporary strains.

What distinguishes Old School from many modern hybrids is its straightforward genetic expression and consistent effects profile. Unlike strains bred for extreme THC percentages or novel terpene combinations, Old School maintains a balanced cannabinoid and terpene profile that produces reliable, predictable effects. The strain has gained a cult following among connoisseurs who appreciate traditional cannabis experiences and serves as a genetic reference point for breeders seeking to incorporate classic traits into new hybrids.

Old School is considered a moderate-difficulty strain to cultivate, suitable for growers with some experience. The plants have a typical flowering time of 8-9 weeks indoors and are ready for outdoor harvest in late September to early October. Indoor yields average 400-500 grams per square meter, while outdoor plants can produce 500-600 grams per plant in optimal conditions.

The strain prefers a controlled indoor environment but can also thrive outdoors in Mediterranean or similar climates. Plants typically reach a medium height of 100-150 cm indoors and 150-200 cm outdoors. Old School responds well to training techniques like topping and low-stress training to manage height and improve light penetration. The plants are moderately resistant to common pests and molds but require good air circulation, particularly during the flowering phase when dense buds can be susceptible to botrytis in humid conditions. Nutrient requirements are moderate, with sensitivity to overfeeding, particularly nitrogen during flowering.
