OG Kush Seeds

OG Kush is the strain the modern “gas” era was built on. For close to two decades it’s been the reference point for fuel-forward West Coast hybrids, and a parent or grandparent to a huge slice of today’s menu. Here’s the straight rundown on OG Kush seeds — where the genetics come from, what the plant does in the tent, and, since we don’t run a pure OG Kush ourselves, the closest photoperiod cut seeds in our catalog you can actually grow.

Genetics & lineage

OG Kush is almost always described as a three-way cross of Chemdawg, Lemon Thai and a Hindu Kush landrace. That’s the pedigree the major seed banks print, and it tracks with what’s in the jar: Chemdawg drives the sharp diesel-and-chem funk, Lemon Thai adds the bright citrus and head-buzz, and Hindu Kush brings the dense, resin-heavy indica backbone.

Worth being straight about: that lineage is the accepted story, not documented fact.
OG Kush first surfaced as a clone-only cut in the early-to-mid ’90s, and its exact parents have never been verified. Some growers argue it’s really a standout Chemdawg phenotype rather than a true three-way cross. Either way, the Chem ’91 genetics at its core are what give OG its signature.

Aroma, Flavor & Terpenes

The OG nose is unmistakable: gas, rubber, and diesel up front, pine and lemon-citrus underneath, finishing earthy, peppery and a touch skunky. Chemically that’s a myrcene–limonene–caryophyllene triad doing the work. The same combo behind the heavy, funky, citrus-fuel character that made the strain famous.

Effects

OG Kush leans indica but works both ends. Expect a fast, euphoric head rush that settles into a heavy, full-body calm — a back-half-of-the-day, decompress-after-work kind of smoke. THC usually lands in the high teens to mid-20s, so it carries real weight; not a beginner’s tolerance test.

Grow Data

OG Kush is a photoperiod plant that stays medium-height and bushy, finishing in roughly 8–9 weeks of flower. Indoor harvests come early, outdoor lands around mid-October. It rewards a controlled room: lower humidity, strong airflow and a little training go a long way, and it can get cranky about feeding and mildew if conditions slip. Yields are moderate, but the bud quality: dense, frosty and loud payoff. Call it intermediate: not the hardest plant, not a freebie either.

The Closest Match in Our Catalog: Lemdawg

Lemdawg cannabis seedsWe don’t breed OG Kush. But if you’re chasing that Chem-fueled, gassy-citrus profile on a photoperiod plant, the closest cut we run is Lemdawg — and it’s a photo-for-photo swap, so you’re trading like for like, not stepping into an autoflower.

Lemdawg crosses our Stardawg “Illuminati” cut — a Chem #4-leaning, Sour Diesel-heavy legacy clone — with Super Lemon Haze #119. That puts the same Chemdawg backbone OG Kush is built on right at the front of the cross, then layers bright lemon over the top. What lands in the jar: skunky Sour Diesel funk, chem, lemon and spice, with its own twist of vanilla and floral funk. Same gassy-citrus neighborhood as OG, different street.

It matches OG on the specs growers actually care about, too — photoperiod, medium height, 8–9 week flower, 19–26% TAC, indica-leaning and relaxing — and two of OG’s three signature terps (limonene and caryophyllene) carry straight over.
