Diagonal
Triangle Kush × East Coast Sour Diesel
Diagonal is a boutique sativa hybrid celebrated for its powerful aroma and resinous flowers. This cultivar is often found in clone-only networks and small-batch releases, prized for its potent effects and complex scent profile.
Appearance
Diagonal produces dense, tapering buds with a high calyx-to-leaf ratio and abundant trichome coverage. The base color is typically olive to deep green, sometimes displaying faint purple hues under cooler temperatures. Mature plants feature deep green fan leaves and pale tangerine pistils that darken to burnt orange.
Under magnification, the glandular trichomes are densely packed, indicating good potential for solventless extractions like bubble hash and rosin. The buds often have a satin sheen when hand-trimmed, preserving the delicate resin layer.
Aroma & Flavor
The aroma is dominated by a high-octane fuel-like scent, complemented by notes of lemon zest, pepper, and pine. Upon breaking or grinding the buds, a distinct diesel and citrus spray emerges, often followed by a softer, doughy Kush undertone. Secondary aromas can include white pepper, cedar, and subtle herbal sweetness.
The flavor profile closely mirrors the aroma, starting with a strong fuel and turpentine taste, followed by lemon oil and black pepper. The exhale reveals a soft, bready Kush note. Vaporizing at moderate temperatures highlights the citrus-diesel characteristics.
Effects
Diagonal is reported to provide balanced yet potent effects, often described as energetic and talkative, with a subsequent calming finish. The initial experience may be uplifting and stimulating, leading to a more relaxed state as the session progresses.
Terpenes & Cannabinoids
This strain typically tests above 20% THC, with total terpene content frequently exceeding 2.0% by weight. The dominant terpenes often include beta-caryophyllene, limonene, and myrcene, with humulene and ocimene contributing to the overall bouquet.
Growing
Diagonal is considered a connoisseur hybrid that can handle training and produces significant frost. It exhibits medium internodal spacing and a noticeable stretch during flowering. The plants generally develop a spear-like bud structure.
Cultivation notes suggest it thrives with canopy management to ensure uniform light penetration. The yield is considered good, particularly from phenos selected for dense, resin-rich flowers.
Origins & Lineage
Diagonal is widely believed to be a cross between Triangle Kush, originating from Florida, and an East Coast Sour Diesel variety. This lineage combines the dense structure and calming finish of Kush genetics with the potent aromatic qualities of diesel strains.
The breeding aims to stabilize diesel aromatics while enhancing bud structure and resin production, reflecting a common trend in modern hybridization. While precise documentation is sparse, this cross is thought to have emerged from elite U.S. genetics of the late 1990s and early 2000s.
