Super Lemon Haze Feminized – Green House Seeds
The undisputed king of citrus sativas and one of the most awarded chapters in global cannabis history resides in Super Lemon Haze Feminized by Green House Seeds. This living legend dominated the international scene by winning the High Times Cannabis Cup consecutively in 2008 and 2009, as well as capturing first place at the IC420 Growers Cup in 2010.
This award-winning masterpiece is born from the genetic union between a special selection of Lemon Skunk and the timeless company pillar Super Silver Haze. The agronomic focus of Franco Loja and the Amsterdam team was to merge the citrus sharpness of Skunk with the psychedelic effect and monumental structure of the Haze genetic.
The feminized version guarantees crops composed exclusively of stable productive female specimens. It completely eliminates the risk of unwanted sexual variations within the cultivation space, offering elite performance for both commercial setups and demanding collectors.
Agronomic Yield and Life Cycle
In terms of ripening times, the plant requires a time window of 10 weeks (about 70 days of continuous photoperiod) in an indoor environment to complete calyx development. Some phenotypes with a higher Sativa tendency can benefit from an additional 5 days to maximize resin accumulation.
Commercial productivity stands at extraordinary levels classified as XXL. It guarantees consistent averages between 500 and 700g/m² within artificially managed grow rooms, while in optimized hydroponic systems it can exceed 800g/m².
Outdoors or in a greenhouse, the hybrid fully expresses its vigorous botanical potential, reaching ideal chop by mid-October in the northern hemisphere. Each specimen can produce up to 1200g of dry flowers if grown in open ground. The THC rate is Extremely High (20-25%).

Structural Development and Aerial Geometry
The architecture of Super Lemon Haze reflects the exuberance of pure sativas. It manifests a slender, open, and vigorous physiognomy, characterized by long internodes and strong lateral branches that grow forming an inverted candelabra structure.
The leaf mass develops with large fan leaves, characterized by exceptionally thin and lanceolate fingers of a bright lime green color. This layout favors intense cellular transpiration, requiring regular selective defoliation interventions to increase air circulation.
The buds accumulate volume assuming an elongated and airy foxtail style, typical of Super Silver Haze. At advanced maturity, the calyxes swell and fuse into extended flower runs, completely submerged by a dense and sticky blanket of glandular trichomes.
Cultivation Protocols and Agronomic Management
The volcanic vegetative vigor of this cultivar demands strict height monitoring. The post-light change stretch is imposing and can triple the initial plant volume within the first three weeks of indoor flowering.
The application of a SCROG (Screen of Green) system or the practice of Supercropping represents the preferred cultivation methodologies. Bending and weaving the flexible branches over the net allows for evenly distributing the LED radiant light across all secondary flower sites.
From a nutritional perspective, the plant manifests a voracious metabolism but demands balanced plans. It tolerates EC values up to 1.7-1.8 at the reproductive peak, but is sensitive to nitrogen excesses, which could prolong the structural stretching phase.
Microclimate management requires a stable VPD value at 1.2 kPa mid-flowering, rising to 1.5 kPa in the final two weeks. It is essential to maintain relative humidity below 45% late in the cycle to protect the internal density of the buds from fungal attacks.
Terpene Analysis and Organoleptic Qualities
The sensory heritage of this variety is an authentic cornerstone of citrus aroma. Terpinolene and Limonene lead the volatile molecular spectrum, releasing pungent aromas of fresh lemon, bitter cedar, grapefruit, and citrus candy.
At the base emerges the Haze heritage of Super Silver, which enriches the composition with scratching accents of church incense, black pepper, damp earth, and industrial metallic nuances.
The smoke is exceptionally fresh, light, and expansive for the respiratory tract, leaving a long-lasting sour-sweet and velvety persistence on the palate. The glass curing phase for at least 45 days eliminates raw vegetal scents, enhancing the purity of the fragrance.
Action Dynamics and Cerebral Impact
With a THC rate that consistently exceeds the 22% threshold, the effect intervenes almost instantly on a purely cognitive level. It releases a powerful surge of mental energy, clear euphoria, radiant good mood, and strong functional creative stimulation.
It does not induce any somatic heaviness, muscle lethargy, or classic couch-lock. On the contrary, the body remains active and dynamic, configuring itself as the perfect choice for advanced daytime consumption (all-day smoke).
It is traditionally sought after in the therapeutic circuit to counteract mental fatigue, alleviate daily psychophysical stress, combat depressive states, and support active working or artistic activity.
Cultivation Slip-ups to Avoid
The most common agronomic error lies in the lack of vertical mechanical supports or support nets. The lateral branches, although elastic, tend to bend or break under the imposing specific weight of the elongated buds during the final three weeks of the cycle.
Another critical risk is linked to nitrogen overfeeding during the pre-flowering phase. Administering high doses of Nitrogen stimulates an uncontrollable vertical stretch, excessively spacing out the reproductive nodes and reducing the final density of the buds.
Comparison with other varieties
Super Lemon Haze vs Lemon Skunk
Lemon Skunk represents the genetic mother of this cross, but it manifests a markedly lower and stockier indica-style structure, with faster flowering times (8 weeks) and a sweeter, earthier lemon aroma. Super Lemon Haze expands the floral volume, doubles the surface resin thickness, and introduces the balsamic and incensed notes of the Haze line.
Super Lemon Haze vs Neville’s Haze
Neville’s Haze represents the pure sativa extremism of the Green House catalog, requiring biblical flowerings up to 14 weeks and delivering an overwhelming and almost psychedelic cerebral high. Super Lemon Haze positions itself as a distinctly more manageable and accessible commercial formula, reducing reproductive times by a month and softening the metallic sharpness thanks to the Skunk component.
Super Lemon Haze vs Arjan’s Strawberry Haze
Arjan’s Strawberry Haze shifts the entire terpene axis toward the sugary sweetness of wild strawberries and dehydrated red fruits, offering a clear and soothing mental high. Super Lemon Haze sits on an opposite sensory track, betting everything on the citrus sourness of fresh lemon and industrial notes of kerosene, guaranteeing a markedly more intense energetic and cerebral drive.
Annibale Seedshop Team’s Opinion
Green House Seeds’ Super Lemon Haze is a living monument of global cannabis agronomy, the variety we recommend blindly to anyone seeking the absolute pinnacle of citrus sativas. Its extraordinary reproductive efficiency and the golden Bag Appeal of its foxtail buds fully justify its legendary fame. It requires attention in indoor vertical space management and careful curing, but repays every effort with monumental harvests and a simply unparalleled lemon and incense flavor.
