Buy Holy Grail S1 Cannabis Seeds – Neptune Seed Bank

Holy Grail S1 feminized seeds from Katsu Seeds revive one of the most iconic strains of the early 2010s. Originally bred by DNA Genetics, the Holy Grail clone-only cut was created by crossing Kosher Kush with OG #18. Katsu has now made it available in seed form for the first time. As a result, growers can finally experience this resin-rich, terpene-loaded Kush in a stable feminized version.

Flavor, Aroma & Effects

The terpene profile of Holy Grail S1 is both complex and loud. Expect diesel, pine, citrus, and sweet hash in every jar. On the inhale, the smoke is thick and earthy. On the exhale, however, the flavor shifts to a lingering hashy sweetness.

The effects are powerful yet smooth. Thanks to the elevated 3–4% CBD content of the original cut, the high is more balanced than many Kush varieties. It delivers body calm, stress relief, and clarity of mind. Therefore, it is a great evening strain for both recreational use and medical relief.

• Aromas: Diesel, pine, citrus, earthy hash

• Flavors: Kush spice, citrus, hashy sweetness

• Effects: Relaxing, therapeutic, functional, body calm

Growing Holy Grail S1

Growing Holy Grail S1 is straightforward, even for less experienced cultivators. The structure leans toward the Kosher Kush side, producing short, bushy plants with tight internodes. OG #18 influence adds stretch and terpene depth.

Flowering takes around 8–9 weeks, and the yields are impressive. Buds are rock-hard, resin-caked, and sticky to the touch. In addition, the high resin content makes this strain a strong choice for extraction.

Why Choose Holy Grail S1?
