Super Lemon Haze (often abbreviated as SLH) is a modern classic and a towering achievement in sativa-dominant breeding. Created in the late 1990s by the legendary late breeder Franco Loja and Arjan Roskam at Amsterdam's Green House Seed Co., it is a masterful cross between the zesty Lemon Skunk and the multi-award-winning Super Silver Haze. This precise genetic pairing resulted in a vigorously growing plant that beautifully combined the soaring, cerebral euphoria of a Haze with the intense, candy-like citrus terpenes of the Skunk.

The strain achieved legendary status almost immediately after winning back-to-back High Times Cannabis Cups in 2008 and 2009. These high-profile victories catapulted Super Lemon Haze to international stardom, with Arjan Roskam once proudly dubbing it the "world's most famous plant." Its aroma is unmistakable: a sharp, intensely sweet blast of lemon drop candy and citrus zest, anchored by subtle earthy and spicy undertones driven by a profoundly limonene-rich terpene profile.

In today's market, Super Lemon Haze remains a highly sought-after staple for daytime users, creatives, and medical patients seeking energetic relief from fatigue and depression. While the original Green House cut remains the gold standard, the immense popularity of the SLH name has led to numerous spin-offs and variations. Experienced growers and enthusiasts often reminisce on Reddit about the unparalleled quality of the 2008-era batches, though the true, 10-to-12-week-flowering Super Lemon Haze continues to be celebrated as a vibrant, mood-elevating masterpiece.

Growing Super Lemon Haze: what to expect

As a sativa-leaning plant, plan for a big stretch after the flip (often 100–200%) — flip earlier than feels natural and keep training options ready. Sativa-leaning plants also generally prefer a lighter feed than heavy indicas. Whatever the listing says, the cut in YOUR tent is the ground truth: log feedings, readings, and photos, and let the trends — not the label — drive decisions.
