Larry OG

Larry OG Feminized Cannabis Seeds by Royal Queen Seeds

Larry OG is a feminized cannabis seed strain from Royal Queen Seeds that brings authentic West Coast OG Kush genetics to your grow room without the transatlantic flight. A cross of OG Kush and SFV OG — a prized cut from California's San Fernando Valley — Larry OG (also called Lemon Larry or Sour Larry) delivers tangy citrus terps, dense frosty buds, and a grow cycle that stays compact and manageable. We've carried Royal Queen Seeds for years, and Larry OG is one of those strains that reminds you why OG genetics still dominate.

Why Larry OG Seeds Deserve a Spot in Your Grow

Larry OG feminized seeds solve a specific problem: you want genuine Cali OG Kush flavour and structure without gambling on bag seeds or hunting for clone-only cuts. Royal Queen Seeds stabilised this cross so you get consistent results from seed — every plant feminized, every plant carrying that SFV OG backbone that made the original Larry OG famous in dispensaries across Los Angeles.

The real appeal here is the terpene profile. Crack open a cured jar of Larry OG and you get hit with sharp lemon zest over a base of earthy skunk and warm spice. It's that classic OG nose — fuel, citrus, and dank rolled into one. If you've grown strains like Royal Queen Seeds' Special Kush 1 and enjoyed the earthy Kush side, Larry OG adds a brighter, more citrus-forward layer on top. It's a step up in complexity.

The one honest limitation: Larry OG's 8–10 week flowering window sits at the longer end for an indica-leaning hybrid. If you're after the fastest possible turnaround, something like Northern Light finishes quicker. But the extra week or two with Larry OG pays off in resin production — those trichomes need time to develop, and rushing the chop means leaving flavour on the table.

Larry OG Grow Specs and Flowering Details

Larry OG feminized seeds produce compact, resilient plants that stay manageable in most indoor setups. Here's what to expect from seed to harvest.

Growing Larry OG Seeds: From Germination to Harvest

Larry OG feminized seeds are rated easy to grow by Royal Queen Seeds, and from what we've seen, that's accurate. These plants don't demand advanced techniques to produce solid results. Here's a straightforward approach.

1. Germinate your Larry OG seeds using the paper towel method or directly in a propagation plug. Keep temperatures around 22–25°C and expect taproots within 24–72 hours. Feminized seeds mean every viable seed becomes a flowering female — no need to sex plants later.
2. Transplant seedlings into good-quality soil once the first true leaves appear. Larry OG responds well to organic growing media. A light, airy mix with perlite gives roots room to spread. Start under 18/6 lighting at moderate intensity.
3. Veg for 3–4 weeks depending on your space. Larry OG stays compact — 80–120 cm indoors at final height — so you don't need a massive veg period. If you're working in a smaller tent, flip to 12/12 once plants reach about 30–40 cm, since they'll stretch briefly during the transition to bloom.
4. Feed with organic nutrients through flowering. Royal Queen Seeds specifically recommends organic fertiliser for Larry OG, and we'd agree — organic inputs tend to preserve terpene complexity better than heavy synthetic feeds. Don't overdo nitrogen once flowers start forming.
5. Watch for dense, lime-green buds coated in frosty trichomes from around week 4–5 of flowering. Larry OG's resin production ramps up significantly in the final weeks. Resist the urge to harvest early — those last 7–10 days before the 8–10 week mark are when terpene and cannabinoid levels peak.
6. Harvest and dry slowly in a dark room at 18–20°C with 55–60% humidity. Cure in glass jars for at least two weeks. Larry OG's citrus-skunk-spice terpene profile develops depth during a proper cure — rush it and you'll get hay instead of lemon fuel.

Larry OG Aroma and Flavour Profile

Larry OG earned the nicknames Lemon Larry and Sour Larry for good reason. The dominant aroma is sharp, tangy citrus — proper lemon zest, not the artificial candy kind. Underneath that top note sits the classic OG Kush foundation: dank earth, peppery spice, and a skunky funk that fills the room the moment you crack a jar. When smoked or vaped, the flavour follows the nose closely — sour lemon on the inhale, earthy Kush on the exhale, with a lingering spice that coats the palate.

If you've grown OG Kush before, Larry OG's terpene expression will feel familiar but brighter. The SFV OG parent pushes the citrus notes further forward than a standard OG cut. According to research published in the journal Plants (2024), OG Kush and its descendants — including strains in the "Larry" lineage — show varied terpene profiles influenced by light spectrum during cultivation. Growing under full-spectrum LEDs tends to bring out the best in these terps.

Larry OG Effects: What to Expect

Larry OG delivers an initial cerebral rush that sharpens focus and lifts mood, followed by a gradual physical relaxation that settles in without flattening you. Royal Queen Seeds describes it as a "daytime high" — and that tracks. It's not a couch-lock strain unless you seriously overdo it. The OG Kush lineage can produce heaviness at higher doses, so if you're newer to OG genetics, start with a smaller amount and see where it takes you.

According to Leafwell's clinical overview, Larry OG can contain high levels of THC, and low doses are recommended as a starting point. Research on cannabis dosing generally suggests that for inhalation, 1–3 mg THC per session can be sufficient for those with lower tolerance (Rainbow Larry Strain review, clinical guidance). The point: Larry OG is potent. Respect the genetics.

Common side effects reported with OG Kush-type strains include dry mouth and dry eyes — keep water nearby. At excessive doses, the Kush lineage can tip from relaxation into drowsiness. That's not a flaw in the strain; it's a signal to dial back next time.

Larry OG vs Other OG Kush Strains

How does Larry OG stack up against other OG-lineage seeds in the Royal Queen Seeds catalogue? Here's a quick comparison.

Larry OG sits in the sweet spot: more complex terps than Special Kush 1, more compact than Royal Moby, and that authentic Cali pedigree that neither of the other two can claim. If you want the closest thing to a dispensary OG from seed, Larry OG is the pick.
