Super Lemon Haze Strain Guide: Effects, THC & When to Use It

Super Lemon Haze is a sativa-dominant hybrid bred by Franco Loja at Green House Seed Company from Lemon Skunk crossed with Super Silver Haze. It won back-to-back High Times Cannabis Cups in 2008 and 2009, tests roughly 18–25% THC with some sources citing up to 26%, and is led by limonene, caryophyllene, and terpinolene. It is a daytime cultivar with a sharp citrus front end.

What Is Super Lemon Haze?

Super Lemon Haze is the strain that made lemon a category. It was bred by Franco Loja for the Netherlands-based Green House Seed Company, crossing Lemon Skunk with Super Silver Haze, and it took first place at the High Times Cannabis Cup two years running.

That pedigree explains the plant precisely. Super Silver Haze is itself a Haze-dominant cross that had already won three consecutive Cups in the late 1990s, and it contributes the long, cerebral, distinctly hazy character. Lemon Skunk contributes the citrus and the Skunk backbone that gives the strain body it would otherwise lack. The result is a sativa-dominant hybrid that is unusually bright without being thin.

Sources describe the split at roughly 70/30 or 80/20 sativa to indica depending on the database, which is a wider spread than usual and reflects the fact that Haze-heavy crosses do not fit the indica-sativa binary cleanly.

At a Glance

The Terpene Profile Is the Point

Most strains are named for a flavor they only gesture at. Super Lemon Haze is not one of them — the citrus is the loudest thing about it, and it comes from a genuinely limonene-forward panel.

Limonene is the headline: sharp lemon rind, and the terpene most associated in user reports with mood elevation. Caryophyllene supplies the peppery base note that keeps the profile from reading like candy. Terpinolene — the same terpene that drives Jack Herer and Durban Poison — adds the herbal, faintly piney complexity that makes it read as a Haze rather than as a citrus novelty.

Behind those three, sources report ocimene, pinene, humulene, linalool, and myrcene in support. That is a broad panel, and it is part of why the aroma is described as layered rather than one-note: lemon and lime first, then incense and earth, then a black-pepper edge on the exhale.

Terpene content varies batch to batch. Read the certificate of analysis on the specific product; our flower guide covers how.

THC and Potency

Reported THC lands roughly between 18% and 25%. Green House and several retailers cite an average nearer 22% to 26%, and individual panels above 25% are documented. The spread is real and we are not naming one figure as settled.

What matters more than the headline number here is the character of the effect. Terpinolene-containing sativas with limonene support tend to be described as fast-arriving and mentally sharp, and Super Lemon Haze has a reputation for hitting quickly rather than creeping. First-time users routinely overshoot for that reason.

CBD is trace.

Effects and Experience

Commonly reported effects are energetic, uplifted, creative, and talkative. Reports describe a fast, sharp cerebral onset — Green House’s own description calls the effect strong and instantaneous — that settles into a sustained, sociable alertness rather than a body effect.

The trade-off is predictable. A fast, stimulating sativa is a poor first choice for anyone prone to cannabis-related anxiety, and racing thoughts at higher doses are among the most common complaints. Standard THC-dominant side effects apply: dry mouth, dry eyes, and elevated anxiety risk at high doses in sensitive users. These are commonly reported experiences, not medical claims, and nothing here is medical advice.

Duration reports are on the longer side for a sativa, which is consistent with its Haze heritage.

Best Uses and Timing

• Morning and daytime. Evening use frequently interferes with sleep, more so than with a balanced hybrid.
• Social settings. The talkative quality is one of the most consistently reported traits.
• Creative work. Reports emphasize mental brightness over the diffuse quality of some older Haze lines.
• Start low. The fast onset is the single most common reason people report an unpleasant experience with it.
• Flower or live resin. The lemon is entirely terpene-driven and largely disappears in distillate. Our vape guide explains why.

Growing Notes

Super Lemon Haze is a Green House commercial line with feminised seed widely available, and grower reports describe a tall, stretchy plant with the extended flowering window its Haze parentage would predict. It is generally regarded as an intermediate grow rather than a beginner one, mostly because of the height and the flowering time.

Specific flowering-week and yield figures vary between the breeder’s own listing and third-party reports, and we are not stating one as settled. Use the figures from the seed bank or clone source you are actually buying from.

How It Compares

Against Jack Herer, Super Lemon Haze is sharper and more citrus-forward; Jack Herer is more piney and a little more even. Against Durban Poison, it is sweeter and more complex where Durban is drier and more anise-like. Against Green Crack, it is more talkative and less narrowly focused. Against Sour Diesel, it is citrus rather than fuel, and generally reported as the friendlier of the two.

If Super Lemon Haze has caused anxiety before, a softer daytime hybrid such as Blue Dream is the usual step down.

Availability

Super Lemon Haze is a long-established Cup-winning cultivar with wide distribution, and it appears on menus in mature adult-use markets as flower, pre-rolls, and cartridges. It is frequently abbreviated to SLH on menus and in delivery apps, so search that if the full name returns nothing.

We do not maintain live dispensary inventory and menus change daily, so we will not claim a specific store has it in stock today. Check the retailer’s own menu. The Portland city hub and the Seattle city hub both sit in markets with strong sativa and Haze representation, and you can find your own market in the state and city directory.

Frequently Asked Questions

What strains make up Super Lemon Haze?

Lemon Skunk crossed with Super Silver Haze, bred by Franco Loja for Green House Seed Company in the Netherlands. Super Silver Haze supplies the long cerebral Haze character, and Lemon Skunk supplies the citrus and the Skunk backbone.

Has Super Lemon Haze won any Cannabis Cups?

Yes. It took first place at the High Times Cannabis Cup in two consecutive years, 2008 and 2009, which is a large part of why the strain spread internationally as fast as it did.

How much THC is in Super Lemon Haze?

Roughly 18% to 25% in most listings, with several sources citing an average nearer 22% to 26% and individual panels above 25%. The spread across sources is real. CBD is trace.

What terpenes are in Super Lemon Haze?

Limonene, caryophyllene, and terpinolene lead the panel, with ocimene, pinene, humulene, linalool, and myrcene reported in support. Limonene supplies the lemon rind, caryophyllene the pepper, and terpinolene the herbal Haze complexity.

Is Super Lemon Haze an indica or a sativa?

A sativa-dominant hybrid. Sources cite the split anywhere from 70/30 to 80/20 sativa to indica, which is a wider spread than usual and reflects how poorly Haze-heavy crosses fit that binary.

Is Super Lemon Haze good for daytime use?

That is its primary reputation. Commonly reported effects are energetic, uplifted, creative, and talkative, and evening use frequently interferes with sleep. Duration reports run longer than for many sativas, consistent with its Haze heritage.

Can Super Lemon Haze cause anxiety?

It can. A fast-onset, stimulating sativa is a poor match for anyone prone to cannabis-related anxiety, and racing thoughts at higher doses are among the most common complaints. The rapid onset is the main reason people overshoot the dose. This is general consumption information, not medical advice.

What does Super Lemon Haze taste like?

Lemon zest, lime, and pink grapefruit up front, over an earthy Haze base, finishing with incense and a light black-pepper note. The citrus is limonene-driven, which means it is largely lost in distillate cartridges. Flower and live resin preserve it.
