Lemongrass Feminized represents one of Amsterdam Genetics’ agronomic peaks regarding the selection of stable and productive citrus profiles. Born from the cross between the famous Lemon Ice and the vigorous Ko Chang (a variety original to Thailand), this cultivar manifests exceptional hybrid vigor.
It is a plant designed for those seeking massive production without the biblical waiting times typical of pure Sativas, while maintaining that cerebral and electric effect sought after by the most demanding growers. The stability of the floral mass and the density of trichomes make it a reference point for modern commercial operations.
Lemongrass by Amsterdam Genetics is a balanced hybrid with a slight sativa dominance, capable of completing flowering in 8-10 weeks. Indoor production stands at 450-600g/m², with THC levels ranging between 20% and 25%.
It develops a slender but solid structure, with predictable vertical stretch management and flowers that tend to take a spear shape, extremely loaded with citrus resin. The aromatic profile is dominated by pungent notes of lemongrass, fresh lemon, and a background of aromatic herbs, offering an energizing and focused effect.
The breeding work behind Lemongrass aimed to stabilize the Thai genetics of Ko Chang, known for its power but also its difficulty of management. According to data reported on Seedfinder, the introduction of Lemon Ice significantly shortened ripening times and consolidated the branch plane, making it a much more manageable plant in closed environments.
A genetic that prefers structural stability over foliar exuberance, concentrating every resource on cannabinoid synthesis.
Documentation on ICMag confirms how Lemongrass inherits the climatic resilience of the Asian component, showing very efficient foliar transpiration even in intense heat conditions.
Lemongrass requires careful management of light and space, as its Asian heritage pushes it toward a marked stretch during the first three weeks of flowering.
Indoors, this variety is the ideal candidate for the SCROG (Screen of Green) system. The flexibility of the branches allows the vegetative volume to be distributed uniformly under the lamp, maximizing light penetration toward the lower calyxes.
It is essential to manage VPD around 1.2 kPa, preventing air from stagnating within the aerial mass, as the density of the flower spears can attract residual moisture. Regarding nutrition, Lemongrass appreciates generous doses of Calcium and Magnesium from the vegetative phase to support its metabolic speed.
Outdoors, Lemongrass expresses its full growth potential. In soils rich in organic amendments, the root volume expands rapidly, allowing the plant to exceed two meters in height. Thanks to its genetic component, it demonstrates above-average resistance to botrytis, as the flowers, though dense, maintain a structure that facilitates airflow.
It is particularly suitable for hot, sunny climates, but its relatively short flowering window allows for excellent results even in more northern latitudes, provided it is protected from the first October frosts.
The terpene profile of Lemongrass is a celebration of citrus notes. Limonene is the predominant terpene, but it is the presence of Terpinolene that gives it that complex aromatic note reminiscent of fresh lemongrass and ginger.
During the drying phase, the sharp lemon smell softens into a more floral and spicy bouquet. In extraction, these volatile terpenes tend to dominate, making Lemongrass a favorite variety for producing “live” resins or BHO extractions, where profile freshness is the main quality parameter. Palate persistence is long, leaving a clean and almost refreshing aftertaste.
With THC levels nearing 25%, the effect is rapid and markedly cerebral. It is not a variety associated with lethargy; on the contrary, many consumers report an increase in concentration and the desire to undertake creative activities.
It is perceived by users as the perfect “daytime” genetic, capable of improving mood without altering social interaction capacity. Physical relaxation is present but acts in the background, preventing anxiety or excessive nervous tension often associated with purer sativas.
The most common error with Lemongrass is excess Nitrogen during the stretching phase. Too high an intake of N in this phase can lead to excessive spacing between nodes, making the branches fragile and less capable of supporting the weight of ripe flowers.
Another risk is space management: without intervention using bending or apical pruning (topping) techniques, the plant can easily reach the lamps in a very short time. Finally, monitoring final humidity is crucial; although resistant, the density of the central calyxes requires a relative humidity no higher than 45% in the last 15 days to correctly crystallize the resin.
Lemongrass is more powerful and productive than the original Lemon Ice. While Lemon Ice is more balanced and contained, Lemongrass inherits a significantly higher energy charge and floral mass size from Ko Chang.
Lemongrass flowers faster and has a less “messy” structure compared to Super Lemon Haze. The effect is less psychedelic and more focused, making it more suitable for those who must maintain mental productivity.
While Amnesia Lemon has a heavier and sometimes disorienting cerebral impact, Lemongrass focuses entirely on clarity and sharp flavor, with a resin production that is more viscous and less powdery.
This variety is not suitable for those suffering from insomnia and looking for help to sleep, as its stimulating component might be counterproductive in the evening hours. It is also discouraged for beginner growers who have very limited vertical spaces (such as small 120 cm boxes) if they are not familiar with the SCROG technique.
In a SCROG system, it is recommended to place no more than 4-5 plants per square meter to allow for correct expansion of the vegetative volume.
Lemongrass handles an EC of 1.8-1.9 well. Exceeding 2.0 can lead to leaf tip burns (nute-burn) given its Thai heritage.
Yes, the FIM technique is excellent for stimulating the growth of multiple main buds and controlling vertical stretch.
Harvest when the trichomes are 100% milky white. Waiting for amber trichomes in this variety tends to degrade citrus notes in favor of earthy ones.
Absolutely yes. In hydroponics, Lemongrass literally explodes, but it requires rigorous pH control at 5.8 to avoid absorption blocks.
Lemongrass is the ultimate choice for those who love sour flavors and a clean “high” effect. It is a plant that gives great satisfaction because it is generous: with little attention, it repays with a heavy, fragrant harvest of high visual impact. We recommend it to those who want a modern Sativa that behaves like a reliable commercial variety. A “must-have” for anyone wanting to add a note of citrus freshness to their jar.
