What is the Super Lemon Haze strain?

Super Lemon Haze was bred in Amsterdam, and it made its name quickly. It took first place in the sativa category at the Cannabis Cup in 2008, then won again in 2009. That back-to-back run turned it into one of the best-known lemon strains anywhere.

The parents explain the profile. Lemon Skunk supplies the loud citrus nose and a productive, easy-feeding frame. Super Silver Haze brings the classic haze side: tall growth, long spear-shaped colas, a sweet and herbal finish, and a lively, heady character. Together they make a plant that smells like lemon candy and grows like a true sativa.

Plan for height. This haze-leaning plant can stretch hard after the flip, so indoor growers manage the flowering stretch from day one. These feminized seeds are bred to produce female plants, so the effort you put into training goes into flower, not males you have to pull.

Super Lemon Haze

How it feels

Consumers commonly describe a fast, clear-headed lift that turns social and creative, with very little body weight. Effects usually last two to three hours.

First 10 minutesBright, zesty rush
An upbeat, energetic head buzz that many people notice right away.
30 to 60 minutesCreative and chatty
Focus and sociability tend to peak, which suits daytime plans.
2 to 3 hoursGentle taper
Most people report a smooth fade rather than a heavy crash.

Commonly reportedEnergeticEuphoricCreativeSociable

Reported THC of 20-25% with a lively sativa character: start low, especially if haze strains are new to you. Commonly reported downsides include dry mouth, dry eyes and, at higher doses, a jittery or restless feeling. General reports, not medical guidance.

Aroma, flavor and terpenes

Fresh lemon zest and lemon candy up front, a sugary middle and an herbal, faintly peppery haze finish. The citrus gets loud in late flower, so plan on a carbon filter.

Flavor notesLemonCitrusSweetHerbal

TerpinoleneFresh herbs, pine

CaryophyllenePepper, spice

Adds the faint spicy edge under the citrus.

MyrceneEarth, ripe fruit

Rounds out the sweet, fruity base.

Dry slowly at about 60°F and 60% humidity, then jar-cure for at least two weeks. A slow cure keeps the lemon top notes from fading into plain hay.

How to grow Super Lemon Haze

Rated moderate. The plant is vigorous, productive and fairly forgiving on feeding; the real skill is controlling its height and stretch indoors.

Indoors

Veg climate: 75-82°F, 55-65% RH
Flower climate: 70-80°F, 40-50% RH
Height control: Top early and flip early
Light: 800-1,000 PPFD in flower (LED)
Training: SCROG net to tame the stretch
Feeding: Light to moderate; avoid heavy doses

Outdoors

Plant out: After last frost, nights above 50°F
Size: 6-8 ft with full sun
Harvest: Mid October
Best fit: Long, warm autumns (USDA 7-10)
Watch for: Early frost before colas ripen
Protect: Stake tall colas; cover if frost threatens

Read the full indoor grow guide

Indoors, Super Lemon Haze can fill a tent fast. Plants usually finish 4 to 6 feet tall, and much of that height arrives in the first few weeks after the flip. Rated moderate, it suits growers who are ready to train it rather than let it run.

Height management

Top early: top at the fourth or fifth node to split the main stem and slow vertical growth.
SCROG: a SCROG net lets you tuck stretching branches sideways into a flat, even canopy through veg and the first two weeks of flower.
Flip early: switch to 12/12 when plants reach about half the height you can afford, because the flowering stretch adds the rest.

Environment

Vegetative: 75-82°F days, 55-65% relative humidity.
Flower: 70-80°F, 40-50% RH. Long haze colas dry out fairly well, but keep air moving through them in the final weeks.
Odor: an exhaust fan with a carbon filter is a must once the lemon smell arrives.

Light and feeding

Aim for roughly 600-800 PPFD in late veg and 800-1,000 PPFD in flower under LED. Watch the tallest tops, since branches that creep up toward the fixture can bleach. Feed lightly to moderately: haze-leaning plants often show burnt leaf tips on heavy nutrient doses.

Harvest timing

Most plants finish 9 to 10 weeks after the switch to 12/12. Haze buds can keep pushing fresh pistils late in flower, and too much heat or light can trigger foxtailing, so judge ripeness by trichomes: mostly cloudy heads keep the effect bright, while a little amber adds some body.

Growing Super Lemon Haze outdoors in the US

Outdoors, Super Lemon Haze becomes a big plant. Expect 6 to 8 feet in full sun and a harvest around mid October at most US latitudes. Plant out after your last spring frost, once nights stay above about 50°F, and give each plant plenty of room and a sturdy stake.

The main risk is the calendar. A mid-October finish leaves little margin where the first frost or cold rains come early, so this strain is happiest where autumns stay warm and sunny. Its long colas are less compact than most indica buds, which helps them shed moisture, but heavy fall storms can still snap branches or start bud rot. Our outdoor planting guide has dates for every USDA zone.

Always check your local rules first. Home cultivation is legal for adults in some states and not in others, and plant limits vary by state.

Will it finish where you live?

ExcellentInland California and the Southwest

Long, warm and dry autumns give the haze all the time it needs to ripen.

FairColorado Front Range and Utah valleys

Strong sun helps, but a mid-October finish often meets the first frost at elevation.

FairMidwest

Cold, wet October weather can arrive before the colas are done.

FairNortheast

Shorter seasons and damp falls make a greenhouse or early cover worth it.

GoodSoutheast and Gulf Coast

The long, hot season suits the sativa side; airy colas handle humidity better than dense buds.

Super Lemon Haze FAQ

Is Super Lemon Haze indica or sativa?

Super Lemon Haze is a sativa-dominant hybrid, usually described as about 70-80% sativa. It grows tall with long colas, and its effects are commonly described as energetic and uplifting rather than heavy.

How strong is Super Lemon Haze?

Our supplier reports THC around 20-25%, which is strong by any standard. Results vary by phenotype, grow conditions and harvest timing, so read that range as typical rather than guaranteed.

How long does Super Lemon Haze take to flower?

Most plants finish 9 to 10 weeks after switching to a 12/12 light schedule indoors. Outdoors in the US, expect a harvest around mid October.

How much does Super Lemon Haze yield?

Indoors, a well-trained canopy can produce roughly 1.6 to 2 ounces per square foot. Outdoors, vigorous plants in full sun can produce roughly 21 to 25 ounces each. Results depend on light, training and season length.

Is Super Lemon Haze good for beginners?

It is rated moderate. The plant is vigorous and fairly forgiving, but its height means newer growers should top early, use a SCROG net and flip to flower sooner than they would with a compact strain.

What does Super Lemon Haze smell and taste like?

Sharp lemon zest and lemon candy lead, with a sweet middle and an herbal haze finish. Terpinolene, caryophyllene and myrcene are the terpenes most often reported.

Where does Super Lemon Haze grow best outdoors in the US?

It does best where autumns stay warm and sunny into mid October, such as inland California, the Southwest and much of the Southeast. In the Midwest, Northeast and higher-elevation Mountain West, frost can arrive before it finishes, so many growers use a greenhouse or grow it indoors.

Did Super Lemon Haze really win the Cannabis Cup?

Yes. Super Lemon Haze won the sativa category at the Cannabis Cup in 2008 and again in 2009. That back-to-back run is a big reason it is still one of the best-known lemon strains.
