400 Blows 1995 Sensi Star X Afghani Heirloom Rks Pheno

1995 Sensi Star × Afghani Heirloom (RKS Pheno)

400 Blows is an indica-leaning hybrid that revives the potent aromas and effects of classic cannabis breeding. It is a cross between 1995 Sensi Star and a Roadkill Skunk (RKS) phenotype of an Afghani Heirloom. This strain aims to restore the distinct sulfuric funk and dense resin production characteristic of older cultivars.

Appearance

This cultivar typically presents as a stout, broadleaf-dominant plant with thick stems and dense foliage. Expect compact internodal spacing and a uniform canopy structure suitable for various training methods. The flowers are generally dense, ranging from golf-ball to soda-can size, with tightly stacked bracts covered in a substantial resin crust. Coloration is usually deep green, sometimes showing purple hues on sugar leaves under cooler temperatures, with pistils maturing to apricot or rust-orange.

The buds feel heavy for their size due to high calyx density, offering efficient trimming with favorable calyx-to-leaf ratios. Growers should ensure good air circulation, especially in late flower, to manage humidity within the dense buds and prevent issues like botrytis.

Aroma & Flavor

The aroma of 400 Blows is characterized by a powerful, classic roadkill skunk profile, often described as burnt rubber, sulfurous, and reminiscent of diesel-soaked asphalt. Underlying this potent scent are more subtle notes of lemon zest, pepper, and warm earth, which become more apparent as the flowers cure. This distinctive olfactory profile is largely attributed to the Afghani Heirloom (RKS Pheno) parentage, which contributes volatile sulfur compounds.

The flavor mirrors the aroma, delivering a pungent and complex experience. While the dominant notes are skunky and diesel-like, hints of citrus, floral, and earthy undertones can be detected. The intensity of the aroma is notable, often requiring double-sealed storage to contain its strong scent bleed.

Effects

As an indica-leaning hybrid, 400 Blows is expected to provide a potent and potentially sedative experience. Its genetic background suggests effects that are deeply relaxing and grounding, aligning with the characteristics of its Sensi Star and Afghani ancestors. Users may experience a significant body high accompanied by a clear-headed yet profound sense of calm.

Terpenes & Cannabinoids

The cannabinoid profile of 400 Blows typically falls within a THC range of 15-25%, with minimal CBD content (<1%). The terpene profile is notable for its complex aromatic contributions, featuring primary drivers such as beta-caryophyllene, myrcene, and limonene. These are complemented by secondary terpenes like humulene and ocimene, which add woody and floral nuances. The strain's signature skunky aroma is also significantly influenced by volatile sulfur compounds (VSCs), which are present at trace levels but dominate olfactory perception.

Growing

400 Blows is considered a low-maintenance cultivar that rewards careful environmental tuning. It exhibits broadleaf dominance with a stout, compact structure, making it suitable for SCROG and low-stress training. Flowering times are generally moderate, and the plant is known for its robust nature and pest resistance inherited from its Afghani lineage. Growers should pay attention to sulfur nutrition and post-harvest handling to optimize its unique aromatic profile.

Origins & Lineage

400 Blows is a modern heirloom hybrid created by crossing 1995 Sensi Star with a specific Roadkill Skunk (RKS) phenotype of an Afghani Heirloom. This cross was developed to recapture the potent, sulfuric aroma and dense resin production of classic cannabis strains from before the year 2000. The goal was to blend the resin-rich, indica-leaning hybrid qualities of Sensi Star with the pungent, old-world characteristics of the RKS Afghani line.
