Quick answer
Super Lemon Haze is Green House Seed Co's Lemon Skunk x Super Silver Haze sativa, back-to-back High Times Cup winner 2008-2009, testing 15-25% THC. Intense lemon-zest flavour, fast energizing creative high.
Super Lemon Haze is the only strain that ever defended the Cannabis Cup title twice running (well, its parent did it first), and one sniff explains the judges' allegiance. Lemon zest so loud it borders on citrus cleaner, skunky haze underneath, and a high that is pure voltage with a smile. It is fast, long, and never foggy - the strain I hand people who claim sativas make them sleepy. The harvest-date rule is real here: fresh SLH is a firework, old SLH is a sparkler. Buy it bright.

The story of Super Lemon Haze
Green House Seed Co (Amsterdam) crossed the Lemon Man's famous Las Vegas lemon-skunk line (via DNA Genetics) with their own Super Silver Haze in the late 90s/early 2000s. When it entered the 2008 High Times Cannabis Cup, it won; in 2009 it defended - becoming only the second strain ever to repeat, after parent Super Silver Haze. High Times later ranked it #13 on their 25 Greatest Strains list. Franco Loja, the beloved breeder who died in 2017, made SLH a legacy project - Green House later released tribute genetics funding his children's education. One controversy for honesty: Ethos Genetics has claimed the actual cross may have been Jack Herer x Lemon Skunk; Green House maintains the official SSH account. The lemon, either way, is undeniable.

Growing Super Lemon Haze
Sativa structure with Skunk practicality: 9-10 week flowering (faster than pure haze), vigorous growth with good yields up to 800 g/m2 in experienced hands, and a stretch that needs managing. Green House notes it suits temperate through tropical climates and finishes mid-October outdoors. The lemon aroma through flower is penetrating - filtration essential. Buds are roundish haze-style with bigger calyxes and bright green colour. Terpene expression is stable; the lemon-zest intensity is why growers put up with the rest.
How to consume Super Lemon Haze
The effect is strong and instantaneous per Green House - fast cerebral lift, long-lasting energy, social and creative. At 15-25% THC the range is wide; prime cuts feel hotter than the number suggests because terpinolene profiles hit clean and bright. A joint or vape in the morning-to-afternoon window is the classic use. Best for: mood elevation, focus, social energy, replacing that third coffee. Not an evening strain unless your evening involves productivity. The zap fades gently; no crash.
Super Lemon Haze vs similar strains
Super Lemon Haze vs Lemon Haze: the simpler original is mellower and gentler; SLH is the Cup-winning heavyweight with the terpinolene complexity. Super Lemon Haze vs Super Silver Haze: the parent is sharper and more racy; SLH sweetens the voltage with lemon candy. Super Lemon Haze vs Tangie: the 2013 citrus champion runs tangerine-skunk; SLH runs pure lemon-zest haze. Two different orange eras. For the whole haze family tree, Haze is where it all began.
Frequently asked questions
What is Super Lemon Haze?

Is Super Lemon Haze indica or sativa?
Sativa-dominant (about 70-80%). Fast, uplifting, long-lasting energy with a clear head - a morning and midday strain.
What does Super Lemon Haze taste like?
Intense fresh lemon zest with skunky haze underneath - terpinolene and limonene lead. Often called the lemon-est lemon strain in cannabis.
How strong is Super Lemon Haze?
15-25% THC depending on the cut. The effect feels strong despite moderate numbers because terpinolene-dominant profiles hit clean and bright.
Why did Super Lemon Haze win two Cannabis Cups?
Its back-to-back 2008-2009 High Times wins made it only the second strain ever to defend the title (after its own parent Super Silver Haze). The loud lemon terpene profile was unlike anything else in competition that era.
Storing Super Lemon Haze
Terpinolene is volatile - the famous lemon zap is the fastest-fading element in the jar. Airtight glass, cool dark storage, 58-62% humidity pack, minimal jar opening. Fresh jars are electric; even well-stored ones mellow noticeably by month three as the zest calms into sweet lemon earth. Buy SLH fresh and drink it fresh - this is a strain where the harvest date on the jar genuinely matters more than most. The haze backbone lasts; the lemon fireworks need freshness.
