Super Lemon Haze is Green House Seed Company's cross of Lemon Skunk and Super Silver Haze, bred in Amsterdam and credited to the late Franco Loja. Green House classifies it 70% sativa, 30% indica. The calling card is lemon zest over pine and Haze wood, and the high lands cerebrally and physically at once. It is the most decorated cultivar in the Green House catalog.
Where It Comes From
What put Super Lemon Haze on the map was not a launch, it was a run. Back-to-back first-place Cannabis Cup finishes in 2008 and 2009 turned a Green House release into a global name, and Amsterdam seed distribution carried it into grow rooms years before licensed American markets existed. By the time dispensaries opened in the States, the plant was already a known quantity behind the counter.
That head start still shows. Ask a shop for a lemon sativa and this is the name that comes back first, even now that the shelf is stacked with candy-fruit hybrids that did not exist when it was winning. It belongs to the Amsterdam era of breeding — plants selected for the judging table and the seed catalog rather than for bag appeal on an American menu.
The Cross
The genetics are Lemon Skunk crossed with Super Silver Haze. Lemon Skunk traces back to Skunk #1 selections chosen for pronounced citrus. Super Silver Haze, an earlier Green House project, combines Skunk #1, Haze and Northern Lights #5. Stack those together and the lemon stops looking like a naming coincidence — the Skunk side supplies sweetness and peel, the Haze side supplies incense-like spice, stretch and resin.
Green House reports a ten-week indoor flowering window, mid-October outdoors in the Northern Hemisphere, and yields up to 800 grams per square meter indoors. The plant runs medium-tall with long branches that take training well, and tall enough outdoors to want support. Beta-caryophyllene, D-limonene and terpinolene are the terpenes called out, which lines up with the peppery, woody edge sitting behind the citrus.
Two things do more work here than a stack of adjectives. In well-cured flower the citrus reads as zest and rind rather than candy. And the Haze spice arrives on the exhale, not before it. Buds run elongated rather than golf-ball dense, light-to-medium green, threaded with orange pistils and heavily resined. Harvest timing, dry and cure decide how cleanly the lemon separates from that spicy base.
What It Left Behind
This is a genuinely decorated plant and the record is specific: first place at the High Times Cannabis Cup in 2008 and 2009 and second in 2010; first at the IC420 Growers Cup in 2010; first at the Seattle Medical Cup in 2012; and second at ExpoGrow-Irun in 2012 followed by first there in 2013.
Every one of those placements belongs to a Green House entry grown by Green House. A licensed producer's Super Lemon Haze inherits the genetics, not the trophy — worth remembering when a menu prints award-winning next to a jar nobody in Amsterdam ever touched. The genetics travel. The grow does not.
The High Rise Take
Lemon over pine and Haze wood, straight from the breeder rather than from retail copy. Most people report it energetic, talkative and creative, and larger amounts can read restless rather than productive, so treat it as a daytime plant and start lower than you think you need to.
