Holy Grail

Holy Grail comes as hybrid flower, weighed out at 14 g or 28 g, and the strain also answers to Holy Grail Kush and Holy Grail OG on Leafly.

DNA Genetics’ Kosher Kush cross

Leafly credits DNA Genetics with breeding Holy Grail from Kosher Kush and OG Kush #18, and describes it as indica-dominant. AllBud traces it to the same pair, writing OG Kush #18 as OG #18; it calls that parent a hybrid and Kosher Kush an indica, and scores Holy Grail itself an even 50/50 hybrid. Both sites call the strain award-winning, and Leafly lists Crunk Cup among its offspring.

Large, dense and sometimes bluish

AllBud pictures large, dense buds, brownish or light green, sometimes with a bluish tinge, on a medium-height plant with relatively few leaves. A Leafly reviewer in May 2024 described thick, fuzzy green buds, and an AllBud grower writing in September 2020 kept a phenotype with dense, very resinous buds.

Pine, spice and an OG-style funk

AllBud likens the aroma to kush mixed with strong spice and citrus and calls the taste piney with an earthy sweetness. Leafly’s write-up names spicy, pungent and pine flavours, while its reviewers vote nutty, woody and earthy to the top. Individual reviewers go further: a sweet, spicy, gassy OG-style funk with hints of tropical fruit (October 2023), a cheesy, piney, nutty taste with a pungent cat-pee smell (May 2024), and pine with a slight sourness (March 2025). The AllBud grower’s phenotype smelled very strongly of diesel, with faint fruity and skunky undertones.

Leafly’s lab data ranks myrcene first among the terpenes, limonene second and caryophyllene third; the second of those is explained in our limonene guide.

20% on Leafly, 25% to 34% on AllBud

Leafly gives Holy Grail about 20% THC and 1% CBG, calls its potency above average and recommends it to experienced consumers. AllBud gives 25% to 34% THC. Leafly says customers report feeling relaxed, euphoric and happy, and a March 2025 reviewer described a tingly, giggly high; AllBud describes a smooth, relaxed buzz that leaves people happy, upbeat and in a creative mood. Both sites show a 4.4 average, from 43 Leafly ratings and 28 AllBud votes.

Set against those figures, Health Canada‘s lower-risk page starts a new smoker on cannabis with no more than 10% THC, taken as a puff or two, and warns that smoked effects can take half an hour to top out. No driving for 6 hours or longer, its lower-risk guidelines add.
