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.

OG Kush Seeds FAQ

1. Is OG Kush indica or sativa?
   It’s an indica-leaning hybrid — a quick cerebral lift that drops into a heavy body calm.
2. What’s the flowering time for OG Kush?
   Around 9-10 weeks indoors as a photoperiod plant; outdoor finishes about mid-October.
3. What does OG Kush smell like?
   Gas and diesel up front, pine and lemon underneath, with an earthy, peppery, skunky finish.
4. How strong is OG Kush?
   THC typically runs high teens to mid-20s, potent, not a beginner strain.
5. Are OG Kush seeds hard to grow?
   Intermediate. It likes low humidity, good airflow and light training, and it’s sensitive to overfeeding and mildew.

The Closest Match in Our Catalog: Lemdawg

We 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.
