1. Summary
Super Lemon Haze (SLH) is a Green House Seed Co. sativa bred from Lemon Skunk × Super Silver Haze. It won the overall High Times Cannabis Cup in Amsterdam in 2008 and 2009.123 Wikipedia credits Franco Loja as breeder and dates the strain to the late 1990s. The breeder's own listing names neither an individual nor a year.12 The parentage is well-supported. Lab data show terpinolene as the dominant terpene more often than limonene, even though the strain is sold on its "lemon" character.

- Type: mostly sativa.
- Breeder: Green House Seed Co. (Franco Loja per Wikipedia).

- Very strong, long-lasting sativa high: common, positive.
- Lemon/citrus haze aroma: common, positive.
- Hermaphrodites, inconsistent feminized seed, low yields for some growers: occasional, negative.1
Paraphrases from Seedfinder growers: in 2018 a haze-dominant phenotype was a strong, long-lasting creeper; in 2022, none of ten seeds showed the expected traits; in 2020, two of three feminized seeds turned hermaphrodite.1
Overall score: 74/100. Grower-weighted: strong praise for the effect, pulled down by complaints about seed quality.
Conflict with lab data: the strain is sold as "lemon", but its profile is mostly terpinolene-dominant.
