Quick answerOG Kush Autoflower is an indica-dominant hybrid that pairs the OG Kush line, first bred in California in the 1990s, with ruderalis so it flowers on its own. Expect a pine, lemon and fuel aroma, reported THC around 20-24%, and a harvest about 9-10 weeks from seed.

What is the OG Kush Autoflower strain?

OG Kush is the profile that much of modern West Coast cannabis was built on. It took shape in California during the 1990s, and its lemon-pine-fuel nose and dense, frosty buds became the benchmark that countless later strains were measured against and bred from.

Most accounts trace its character to three influences: a sharp, fuel-heavy parent that supplies the gas, a citrus-forward Thai line that brightens the top notes, and Hindu Kush mountain genetics that add tight bud structure and a calm body feel. This autoflower version folds in ruderalis, a hardy subspecies that starts flowering by age rather than by day length.

The payoff is the OG experience without the photoperiod fuss. Plants stay 2 to 4 feet tall, branch sturdily, and fill out with lime-green buds dusted in fine frost and edged with yellowish sugar leaf. Phenotypes tend to run uniform, so a pack of seeds usually gives you a matched, predictable garden.

How it feels

Consumers commonly describe a happy, easygoing lift followed by warm body relaxation that settles in without fully knocking them out at moderate doses. The munchies are a famously reliable part of the ride.

First 10 minutesCheerful lift
A smiling, carefree mood arrives quickly and loosens the day.
30 to 60 minutesWarm body ease
Relaxation spreads through the shoulders and limbs while the head stays clear.
1 to 2 hoursSnack o'clock
Appetite shows up on cue; many people save it for dinner or a slow evening.

Commonly reportedRelaxedEuphoricHappyHungry

Reported THC of 20-24% is plenty for most people, so start low. Commonly reported downsides include dry mouth and dry eyes, and at high doses some people report anxiety or paranoia. General reports, not medical guidance.

Aroma, flavor and terpenes

Crushed pine needles and lemon peel on top, a sharp fuel note underneath and an earthy, woody finish. Even a small auto gets pungent late in flower, so a carbon filter is worth running.

Flavor notesPineLemonFuelEarthy

MyrceneEarth, herbs

Grounds the profile with a musky, earthy base.

LimoneneLemon, citrus peel

Drives the bright lemon top note OG is known for.

CaryophyllenePepper, wood

Adds the spicy, fuel-adjacent bite on the exhale.

Harvest, hang whole branches at about 60°F and 60% humidity for 10-14 days, then cure in jars for at least two weeks so the lemon note does not fade into plain earth.

Read the full indoor grow guide

OG Kush Auto suits small spaces and first-time growers. A 2×2 or 3×3 ft tent holds one to four plants comfortably, and because it is an autoflower, you keep the same light schedule from sprout to chop. Photoperiod OG cuts are known for being finicky about temperature; the ruderalis in this version makes it far more forgiving.

Start it right

Autoflowers run on a fixed internal clock, so any early stress comes straight out of your yield. Germinate the seed, then plant it directly into its final 3 to 5 gallon container in a light, airy mix. Water in a small circle around the stem for the first week or two and let the roots chase moisture outward.

Environment

Early growth: 72-80°F with 55-65% relative humidity.
Flower: 68-80°F and 40-50% RH. Keep a fan moving air across the main cola as it stacks.
Light: 18/6 or 20/4 the whole run, about 200-400 PPFD for seedlings rising to 600-900 PPFD in flower under LED.

Training and feeding

Skip topping. Gentle low-stress training between weeks 2 and 4, simply bending the main stem and tying it down, opens the side branches to more light. Stop training once flowers appear. Feed at roughly half the strength you would give a large photoperiod plant, and add cal-mag under LED if leaves show rusty spots.

Harvest timing

Most plants finish about 9 to 10 weeks from seed, with slower phenotypes and outdoor plants taking up to 12. Check trichomes with a loupe: mostly cloudy heads keep the lift bright, while 10-20% amber gives a heavier body feel.

Seed to jar in about 15 weeks

A typical indoor run under 18/6 or 20/4. The plant decides when to flower; you just keep conditions steady.

Growing OG Kush Auto outdoors in the US

Outdoors, OG Kush Auto is about timing rather than latitude. It finishes roughly 10 to 12 weeks after sprouting no matter how long the days are, so you can plant it once the last spring frost has passed and nights stay above about 50°F, then harvest in midsummer.

In states with long, warm seasons, that opens the door to two or three back-to-back runs: one in spring, one in early summer and a final one that wraps up before autumn rain. In short northern seasons, a single run started in late May or early June finishes well ahead of the first frost, which is something many photoperiod strains cannot promise. Its 2 to 4 foot height also keeps it discreet on a patio or behind a fence. Our outdoor planting guide lists dates by USDA zone.

Check your local rules before planting. Home cultivation is legal for adults in some states and not in others, and plant counts vary. See marijuana laws by state.

Will it finish where you live?

GoodInland California and the Southwest

The long season fits 2-3 runs; give small pots afternoon shade in peak heat.

ExcellentColorado Front Range and Utah valleys

Dry air and a fast clock beat short mountain summers and early frost.

ExcellentMidwest

A late-May start finishes by August, leaving time for a second run.

GoodNortheast

It wraps up before fall rains; keep airflow up through muggy August.

GoodSoutheast and Gulf Coast

Spring and fall runs sidestep the worst summer humidity for dense buds.

OG Kush Auto FAQ

Is OG Kush Autoflower indica or sativa?

It is an indica-dominant hybrid with ruderalis added so it flowers automatically. The plant stays short and sturdy, and its effects lean toward relaxed and happy rather than racy.

How strong is OG Kush Auto?

Our supplier reports THC around 20-24%, which is strong for an autoflower and in line with the classic photoperiod line. Actual results vary with phenotype, light and harvest timing, so treat the range as typical rather than guaranteed.

How long does OG Kush Autoflower take to grow?

Most plants are ready about 9 to 10 weeks from seed indoors under an 18/6 or 20/4 schedule. Outdoors, plan on roughly 10 to 12 weeks from sprouting.

How much does OG Kush Auto yield?

Indoors, expect about 0.8 to 1.3 ounces per square foot with good light. Outdoors, each plant typically gives about 2 to 4 ounces, and you can often fit more than one run into a season.

Is OG Kush Autoflower good for beginners?

Yes. It is rated easy, needs no light schedule change or topping, and its ruderalis genetics handle temperature swings better than photoperiod OG cuts. Start it in its final pot and keep feeding light.

What does OG Kush Auto smell and taste like?

Pine and lemon peel lead, with a sharp fuel note and an earthy finish. Myrcene, limonene and caryophyllene are the terpenes most often reported for the OG family.

Where does OG Kush Auto grow best in the US?

Almost anywhere with a frost-free window of about three months. Colorado, Utah and the Midwest suit it especially well, while warm southern and western states can fit two or three runs a year.

Can I get multiple harvests a year outdoors?

In long-season states, yes. Because it finishes 10-12 weeks after sprouting regardless of day length, you can stagger spring, early-summer and late-summer plantings for two or three harvests.
