OG Kush Seeds

Feminized seeds produce the full-expression OG Kush phenotype with the highest yield potential — up to 500g/m² indoors and 550g per plant outdoors — and are the most widely available format across seedbanks like Royal Queen Seeds, Growers Choice Seeds, and ILGM. Autoflower seeds complete their cycle in 8–10 weeks from seed and are available from Homegrown Cannabis Co and Dinafem Seeds, making them a practical choice if you're running multiple cycles or working with a constrained setup. Regular seeds, available from Humboldt Seeds, are the format of choice for breeders who want to work with OG Kush's Chemdawg x Lemon Thai x Pakistani Kush genetics to create new crosses or preserve the strain's genetic diversity. For most buyers focused on end product rather than breeding, the choice is between feminized and autoflower based on grow cadence and target output.

OG Kush seeds consistently test at 19% THC across verified genetic sources — a figure that puts it firmly in the high-potency category without crossing into the extreme ranges that can make some modern strains less versatile. This THC level is a direct function of the Chemdawg and Pakistani Kush lineage, and it's one of the reasons verified genetics from established seedbanks like Royal Queen Seeds or Homegrown Cannabis Co matter for this particular cross. Unverified OG Kush seeds sold under the same name can vary considerably in actual cannabinoid output, so sourcing from seedbanks that carry tested genetics is directly relevant to hitting that 19% benchmark.

OG Kush is rated as an experienced-grower strain, which is worth taking seriously before purchasing. This isn't a marketing caveat — the three-way cross genetics (Chemdawg x Lemon Thai x Pakistani Kush) produce a plant that rewards skilled cultivation but can underperform significantly without it. If you're newer to growing and have your eye on OG Kush, the autoflower format from Homegrown Cannabis Co or Dinafem Seeds is a lower-risk entry point than jumping straight into the feminized photoperiod version. For buyers who are committed to the full feminized experience, purchasing from a seedbank with a strong germination guarantee like Growers Choice Seeds (90% germination pledge) provides some protection on your initial investment.

OG Kush seeds for sale are currently available from seven seedbanks: Homegrown Cannabis Co (feminized and autoflower), Royal Queen Seeds (feminized), Growers Choice Seeds (feminized), ILGM (feminized), Humboldt Seeds (regular), and Dinafem Seeds (autoflower).
