Editorial profile

Grand OG in detail

Origin & classification

Grand OG was developed by ROOR Seeds Amsterdam from True OG and White Widow. The cross combines a classic West Coast OG with one of the best-known Dutch resin strains. Grand OG is approximately three-quarters indica-dominant, but grows taller and more stretched than its classification might initially suggest.

Aroma & taste

Earth, gas and a kush-like pine note take center stage aromatically. Fresh herbs, wood and a subtle fruity sweetness complement the dry core. Myrcene suits the earthy fullness, caryophyllene the spicy contour and humulene the bitter, woody side. The profile feels classic and powerful without tipping into pure diesel sharpness.

Terpene profile

The effect tendency is strong, relaxed and body-focused. An elevated, carefree mood may accompany the onset before a calm body buzz spreads. Grand OG is therefore not exclusively heavy, but clearly retains its indica-dominant focus. The experience favors lasting calm over a fast, bright impulse.

Effect tendency

Grand OG is reported to contain approximately 22 to 30 percent THC. The flowering time is around eight to nine weeks. The strain produces dense, resin-rich flowers and reaches a medium yield. Despite its indica-heavy genetics, it can develop a relatively tall structure, which should be considered when planning space.

Cannabinoids, flowering & appearance

True OG and White Widow sit directly above Grand OG in the family tree. True OG leads further to OG Kush and therefore into classic Kush and West Coast lineage. White Widow combines Brazilian Sativa and South Indian Indica lines. In the deeper generations, OG, Kush, tropical Sativa and old Indica heritage come together.

Further classification

Compared with True OG, Grand OG has greater resin fullness, freshness and a more refined fruity side. Compared with White Widow, it comes across as earthier, gassier and heavier in the body. Its own character lies in this classic combination: a powerful OG foundation expanded by the balanced structure and strong resin production of the White Widow family.
