What is the Lemon Haze Auto strain?

The photoperiod Lemon Haze is a haze-family sativa created by crossing Silver Haze with Lemon Skunk. It earned a loyal following for one reason above all: the smell. Grind a cured bud and the room fills with something close to freshly zested lemons, backed by the sweet, incense-like spice that haze lovers chase.

The autoflower version keeps that profile and adds a ruderalis line, Lowryder #2, to the mix. Ruderalis genetics come from short-season regions where plants flower by age rather than day length. Bred into Lemon Haze, they turn a tall, slow sativa into a 2 to 4 foot plant that starts blooming on its own a few weeks after germination and is usually ready 8 to 10 weeks from seed.

You still get the sativa-leaning structure: a central cola, slender side branches and long, lime-green buds frosted with resin. What you lose is the waiting, along with the separate veg room and the light timer changes a photoperiod haze demands.

Lemon Haze Auto

How it feels

Consumers commonly describe a clear, sunny lift that sharpens focus and gets conversation moving, with only light body weight. It is usually saved for daytime and lasts around two hours.

First 10 minutesBright head rush
A quick wave of cheerful, alert energy behind the eyes.
30 to 90 minutesCreative cruise
Many people report an easy, chatty focus suited to projects and errands.
About 2 hoursGentle landing
The buzz tapers off cleanly, leaving a relaxed but awake mood.

Commonly reportedUpliftedEnergeticCreativeHappy

Racy sativa-leaning strains can feel jittery at high doses, so start small. Dry mouth and dry eyes are the most commonly reported downsides. General reports, not medical guidance.

Aroma, flavor and terpenes

Sharp lemon zest leads, followed by sweet citrus candy and a dry, earthy haze spice on the exhale. The smell builds fast in late flower, so run a carbon filter even on a small tent.

Flavor notesLemonCitrusSweetEarthy

LimoneneLemon, orange peel

Drives the zesty, juicy top note.

TerpinoleneFresh herbs, pine, citrus

Adds the airy, sparkling haze character.

CaryophylleneBlack pepper, wood

Gives the earthy, spicy back end.

Citrus terpenes are the first to fade. Harvest in the cool morning hours, dry for 10-14 days near 60°F and 60% RH, and burp jars daily during the first week of cure.

How to grow Lemon Haze Auto

Rated moderate. The plant is quick and hardy, but its sativa side stretches more than a typical auto, so plan your light height and keep training gentle and early.

Indoors

Light schedule: 18/6 or 20/4 from sprout to chop
Container: 3-5 gallon final pot, no transplants
Early growth: 74-82°F, 55-65% RH
Flower climate: 70-80°F, 40-50% RH
Training: LST in weeks 2-4 only; never top
Light intensity: 600-900 PPFD (LED) once established

Outdoors

Plant out: When nights hold above 50°F
Size: 2-4 ft, open and branchy
Harvest: 10-12 weeks after sprouting
Runs: Back-to-back runs from May to September in the South
Short seasons: A late-May start finishes in August up north
Sun: 8+ hours of direct light for best yield

Read the full indoor grow guide

Lemon Haze Auto rewards a grower who sets things up right on day one. Because the plant runs on its own internal clock, every week of stunted growth comes straight out of the harvest. Rated moderate, it suits someone with a grow or two behind them, though a careful beginner can manage it.

Pot and medium

Germinate the seed and plant it directly in its final 3 to 5 gallon fabric pot. A light, airy mix with extra perlite or a coco coir blend lets young roots spread fast. Water a small ring around the seedling at first, then widen it as the root zone fills the pot.

Light and stretch

Keep lights on 18/6 or 20/4 for the entire run, with no switch to 12/12. Expect a noticeable flowering stretch around weeks 4 to 6 as the haze genetics show through. Leave at least 18 inches of headroom above the pot and raise the fixture as the plant climbs.

Training

Do not top or fim this plant. Use soft low-stress training in weeks 2 to 4 only: bend the main stem sideways and tie it down so the side branches rise into an even canopy. Once pistils appear, stop moving branches and let the plant bulk up.

Feeding and harvest

Start nutrients at about half the label rate and increase only if lower leaves pale. Sativa-leaning autos can foxtail under too much heat or light, so keep canopy temperatures under about 82°F late in flower. Harvest by trichomes: mostly cloudy heads keep the effect crisp and energetic.

From seed to cured jar in about 14 weeks

A typical indoor run under 18/6 or 20/4. There is no veg period to plan; the plant starts flowering on its own and is usually ready 8 to 10 weeks after it sprouts.

Growing Lemon Haze Auto outdoors in the US

Outdoors, this auto ignores day length, which opens up the calendar. Plants reach 2 to 4 feet and are ready about 10 to 12 weeks after sprouting, producing roughly 4 to 5 ounces each in full sun. Start seeds once nights stay above 50°F and the plant will flower on schedule regardless of when the longest day falls.

In warm southern states that means two or even three harvests a year: a spring run sown in April or May, a midsummer run, and sometimes a late one that finishes before fall rains. In the northern tier and at elevation, where the frost-free window is short, a single late-May start still finishes in August, well ahead of the first cold snaps that can ruin a photoperiod sativa.

The open, spear-shaped buds dry quickly after rain, which helps in humid areas. Our outdoor planting guide covers start dates by USDA zone. Check your local rules before planting: home cultivation is legal for adults in some states and not others. See marijuana laws by state.

Will it finish where you live?

ExcellentInland California and the Southwest

Strong sun and a long season make room for multiple runs; water often in July heat.

ExcellentColorado Front Range and Utah valleys

High-altitude light suits a sun-loving sativa, and a June start beats September frost easily.

GoodMidwest

One or two runs fit between spring frost and fall rain; give it the sunniest spot you have.

GoodNortheast

A summer run finishes before wet autumn weather, and the airy buds shed moisture well.

GoodSoutheast and Gulf Coast

The season is long enough for several harvests, but space plants wide to keep air moving.

Lemon Haze Auto FAQ

Is Lemon Haze Auto indica or sativa?

It is a sativa-dominant hybrid with ruderalis genetics added for autoflowering. It grows taller and airier than most autos and its effects lean toward an energetic, clear-headed lift.

How strong is Lemon Haze Auto?

Our supplier reports THC around 17-20%, with CBD near 0.4%. That is a solid, approachable potency for daytime use, though actual results shift with phenotype, environment and harvest timing.

How long does Lemon Haze Auto take to flower?

Most plants are ready about 8 to 10 weeks after the seed sprouts indoors, with lights on 18/6 or 20/4 the whole time. Outdoors, plan on roughly 10 to 12 weeks from sprouting.

How much does Lemon Haze Auto yield?

Indoors, a well-tuned tent can produce about 1.6 ounces per square foot. Outdoor plants in full sun typically give 4 to 5 ounces each, depending on pot size, light and how well the early weeks go.

Is Lemon Haze Auto good for beginners?

It is rated moderate. The auto timing is forgiving, but the sativa stretch means you need to manage light height and skip topping, so it suits growers who have read up or have one grow under their belt.

What does Lemon Haze Auto smell and taste like?

Expect sharp lemon zest and sweet citrus up front with an earthy, peppery haze spice underneath. Limonene, terpinolene and caryophyllene are the terpenes most commonly reported.

Where does Lemon Haze Auto grow best in the US?

Sunny regions like inland California, the Southwest and Colorado give the best results and room for several runs. Because it ignores day length, it also finishes well in short northern summers when started in late spring.

Can I get more than one outdoor harvest of Lemon Haze Auto per year?

Yes, in many places. Since each plant is done 10 to 12 weeks after sprouting, growers in warm states often stagger two or three runs between spring and early fall, while northern growers usually fit one or two.
