Super Silver Haze Feminized Sativa – Green House Seeds
The Super Silver Haze Feminized by Green House Seeds is the undisputed icon of the nineties Haze lines. This strongly sativa-dominant cultivar expresses overwhelming vegetative vigor. It requires a firm hand in the grow room to tame its pronounced stretching.
It is not a plant for beginners looking for fast cycles. It develops very long floral lances that need mechanical support in the final stages. It rewards the grower’s patience with an exceptional calyx-to-leaf ratio and resin with a pungent smell of incense and metallic citrus.
Super Silver Haze Feminized in brief
This Dutch queen requires about 10-11 weeks of flowering to complete maturation. Indoors, commercial yields settle around 400-500g/m² under high-intensity lamps. Laboratories show a THC level of 21%, guaranteeing an electric and long-lasting mental impact.
The aromatic profile is a timeless classic: spicy wood, lemon, and earthy incense. Thanks to its aggressive root system, it tolerates humidity very well and adapts perfectly to cultivation in greenhouses or temperate outdoor environments.

Intro and History
Winner of countless cups, its genetics is the result of masterful breeding work detailed on Seedfinder. The union of Skunk, Northern Lights, and Haze created a quality standard that has endured for decades. Dutch breeders tamed the Haze energy by providing structure through the Northern Lights component.
A genetic that converts long photoperiodic times into floral lances of extreme density.
Cultural management and yield parameters
Indoor
Inside the tent, this variety requires a timely switch to the 12/12 photoperiod. Its post-switch vertical elongation can easily triple the plant’s size. The use of support nets to widen the vegetative plane is practically mandatory to expose the lower floral sites.
Nutritionally, it requires initial parsimony. Avoid nitrogen buildups. From the sixth week, nutrient absorption suddenly accelerates: EC can rise to 1.8-2.0 with massive doses of phosphorus and potassium. Keep the VPD around 1.2 kPa to favor the continuous transpiration of its thin leaves.
Outdoor
Outdoors, it becomes a real tree. Its root platform explores the soil deeply, firmly anchoring the plant against autumn wind gusts. Many growers on GrowDiaries testify to its excellent performance in greenhouses, where late flowering is protected from cold rains.
The long floral lances resist pathogenic stagnation very well thanks to the airy structure of the calyxes. However, in areas with high autumn humidity, it is advisable to carefully inspect the center of the oldest buds during the first weeks of November.
Terpene profile analysis
The bouquet of Super Silver Haze is pungent, sharp, and metallic. An initial wave of sour lemon and pine hits the nose. Immediately after, a deep and unmistakable note of incense and sandalwood emerges, a direct legacy of the old equatorial lines.
With a slow cure at a controlled temperature (18°C), the spicy hints of caryophyllene blend with terpinolene in a complex sweet and sour dance. In ice and water extractions, this terpene profile concentrates into a clear resin, with a spicy flavor that lingers on the palate for hours.
Effect and stimulation: what to expect
With THC levels stable over 20%, the impact of this Haze is a pure explosion of mental energy. It hits quickly, sweeping away any trace of fatigue. Users describe it as a powerful creativity catalyst, ideal for tackling long work sessions or stimulating conversations.
Physical relaxation is almost completely absent in the first few hours of the effect. It is a cultivar traditionally associated with morning or daytime use. Perceived by enthusiasts as the perfect remedy to find inspiration without ever clouding cognitive clarity.
Technical advantages
- Vegetative vigor: Explosive development that allows rapid recovery from pruning and stress.
- Mold resistance: Open floral architecture that favors the constant oxygenation of the calyxes.
- Apical yield: Production of massive central lances if properly directed towards the light.
- Haze identity: Historical terpene profile, extremely sought after in premium commercial circuits.
Errors that ruin the harvest
The most dramatic error is underestimating its height. Leaving it in vegetative growth for too long means finding the flowers inexorably burnt against the LED modules. Switch to flowering very early.
Another common mistake is hasty harvesting. The metallic and incense terpenes fully develop only between the tenth and eleventh week. Cutting earlier means sacrificing real weight and effect intensity. Finally, nitrogen overfeeding in full bloom: this genetics reacts by blocking calyx development and injecting a harsh taste into the final resin.
Super Silver Haze vs Other Queens
Super Silver Haze vs Amnesia Haze
Amnesia presents an olfactory profile shifted more towards chemical lemon and a distinctly more disorienting effect. Super Silver offers a spicier and woodier aroma, keeping the consumer at much higher levels of clarity.
Super Silver Haze vs Jack Herer
Jack Herer, having a stronger Northern Lights influence, completes the cycle slightly earlier and develops denser flowers. Super Silver guarantees a more extreme elongation and much longer, airier floral lances.
Super Silver Haze vs Lemon Skunk
Lemon Skunk flowers in a short time and is very suitable for novices, but the effect fades quickly. Super Silver Haze wins on the duration of mental stimulation and aromatic complexity, though requiring more agronomic experience.
Who it is not recommended for
This variety is strictly not recommended for those growing in low tents or micro-grows, due to the physiological difficulty in managing its elongation. In terms of effects, it is absolutely not suitable for consumers prone to tachycardia or those looking for a sedative variety to promote evening relaxation and induce sleep.
FAQ
Can I grow it in very small pots to contain its height?
Yes, using 5-7 liter final pots indoors will partially limit root system development, helping to mitigate the strong vertical push post-switch.
How long does the stretch last after switching to 12/12?
Vertical elongation is among the longest on the market, often continuing until the fourth week of late flowering.
Does it respond well to super-cropping?
Excellently. Squeezing and bending the main stems horizontally helps strengthen the branch plane and align the buds under the light without breaking them.
Is it suitable for very dry climates?
The large leaf surface area makes it transpire a lot of water. In excessively dry climates, it is necessary to guarantee frequent and abundant watering, maintaining a stable supply of calcium and magnesium.
Will the trichomes ever turn completely amber?
Rarely. In pure Haze lines, the ideal peak is reached when the trichomes are 80% milky and 20% amber; waiting longer degrades the peculiar electric potency.
