Indica Dominant · DNA Genetics
Lemon OG
Lemon OG is the DNA Genetics cross of Las Vegas Lemon Skunk and OG #18 released in the late 2000s, an indica-dominant hybrid that brings a sharp lemon citrus note to the OG Kush family. The strain anchors a cluster of lemon-leaning OG variants — Super Lemon OG, Lemon OG Kush, and Lemon Skunk hybrids all trace back to similar parentage. Plants finish in eight to nine weeks indoors with medium-density buds, bright lemon-green coloration, and a frosty trichome layer that develops late in flower. The high is calm and physical with a sharp citrus inhale that opens cerebral before settling into a deep body relaxation over the first forty minutes, which makes it a common evening or pre-sleep pick.

Terpene profile
The aromatic compounds below shape how Lemon OG smells, tastes, and ultimately feels in the body.
- dominant
Limonene
Uplifting citrus — typically associated with mood elevation and stress relief.
- secondary
Myrcene
Sedating, musky, herbal — commonly linked to couch-lock effects.
- secondary
Caryophyllene
Peppery and spicy — the only terpene that binds CB2 receptors, studied for anti-inflammatory action.
- minor
Pinene
Alert and pine-forward — associated with mental clarity and bronchodilation.

Feed schedule for Lemon OG
These EC and NPK targets are starting points calibrated for the strain's Indica lean and moderate difficulty rating — not gospel. Drop 15-20% off any EC ceiling on your first run and let the plant tell you where it actually wants to feed.
Suggested feed schedule
- Late veg
- 1.4-1.6 EC
- Early flower
- 1.5-1.7 EC, NPK 2-3-4
- Mid flower
- 1.8-2.0 EC, NPK 1-4-6
- Late flower
- 1.6-1.8 EC
- Final week
- Plain pH-balanced water for the last 7-10 days; light flush if you ran nutrients on the higher end.

What to expect through the grow cycle
Lemon OG is documented with a 9-week flower and a compact stretch typical of indica-leaning structure. The visual below maps a documented 13-week cycle built from 4weeks of vegetative growth and the strain's published flowering window.
Published grow reports for Lemon OG concentrate the most observational notes on the late-flower ripening window. This timeline is descriptive — it reflects what reports document, not a how-to. Actual week-to-week behaviour varies with phenotype, light intensity, pot size, and environment.
Phase details
- Veg (weeks 1-4)
- The documented vegetative period for Lemon OG. Plants establish root structure, leaf canopy, and node count before flower triggering, with a moderate difficulty rating shaping how forgiving the early canopy work tends to be.
- Stretch (weeks 5-7)
- Lemon OG is documented as having moderate stretch. Reports describe the plant roughly doubling in height during this phase as the indica-leaning structure establishes its final flowering frame.
- Bud sites (weeks 8-9)
- Pre-flowers form at the nodes and calyxes begin to develop. Grow reports for Lemon OGnote this as the window where the canopy's eventual bud distribution becomes visible.
- Bud development (weeks 10-11)
- Flowers thicken and calyxes fatten through this phase. Documented Lemon OG runs show the bulk of visible flower mass accumulating here, with resin production accelerating toward the end.
- Ripening (week 12)
- Trichomes transition from clear toward cloudy and amber. Reports for Lemon OG describe the Limonene-led terpene profile maturing through this window, with aroma sharpening week over week.
- Final (week 13)
- Calyx swelling is documented as complete and the harvest window opens. Published Lemon OG runs end here, within the 8-9 week flowering range reported by the breeder.

Common questions about Lemon OG
Is Lemon OG the same as Super Lemon OG?
No — Super Lemon OG is a separate hybrid built from similar parentage. Lemon OG is the original DNA Genetics release; Super Lemon OG adds Las Vegas Lemon Skunk back as a third generational input.
Is Lemon OG good for sleep?
Yes — despite the bright lemon flavor, the high tilts indica-leaning within thirty minutes. Most users report it as a calmer evening strain rather than a daytime functional pick.
