Bulk Seed Bank’s Master Kush Grand is a cornerstone of the Amsterdam cannabis scene, a staple on coffee shop menus since the early 1990s.
This strain represents the quintessential high-altitude Indica genetics, a stabilized cross between Hindu Kush selections and Afghan landraces. It’s designed for those seeking maximum resin production and an uncompromising physical effect.
Its most prized characteristic, besides potency, is its discretion during cultivation: unlike many other modern strains, Master Kush emits a very subtle odor during growth, making it a strategic choice for those who need to maintain a low profile.
Choosing Master Kush Grand means returning to the origins of “charas,” opting for a robust, productive plant with universally recognized therapeutic value.
Master Kush Grand in brief
If you’re looking for a pure (100%) Indica that’s both productive and easy to manage, Master Kush Grand is the benchmark. With a THC level between 20% and 25%, it offers total and long-lasting relaxation.
It flowers in 8-9 weeks, providing generous harvests (up to 625g/m² indoors) and outdoor yields that can exceed a kilogram per plant as early as mid-September. The flavor is classic Kush: moist earth, incense, and Indian spices, with trichome production ideal for extractions.

Genetic Analysis: From “High Rise” to Legend
Originally known as High Rise, this strain was developed in Amsterdam’s residential buildings before being renamed Master Kush. Its genetics are a return to pure lines from the Hindu Kush mountains, crossed to maximize resistance and resin production.
Being a 100% indica, the plant exhibits almost no sativa stretch, maintaining a dense structure with broad, dark leaves. The stability of this strain makes it a favorite base for breeders creating new hybrids, but in its “Grand” form from Bulk Seed Bank, it offers the authentic, undiluted experience of original Afghan strains.
Morphology and resin production
Master Kush Grand grows like a typical compact bush. The distance between internodes is minimal, resulting in the formation of extremely thick and heavy main colas.
From historical analysis of Kush strains: “Master Kush was originally named High Rise, taking its name from the Amsterdam building where it was first bred; it is specifically prized by hash-makers because its genetic lineage is directly linked to the traditional hand-rubbed charas production of the Hindu Kush mountains.”
This genetic predisposition results in flowers that, once fully mature, appear literally glazed with resin, making trichome separation (both dry and with ice) extremely profitable.
Indoor Cultivation: Discretion and XXL Yield
Indoors, Master Kush Grand is one of the easiest plants to manage, even for beginners.
The Advantage of Low Odor
One of the unique traits of this strain is that, during the vegetative stage and most of the flowering period, the aroma is very subtle and almost imperceptible. This doesn’t mean the final product is flavorless, but rather that the plant “retains” the terpenes within the resin without saturating the air like a Skunk would.
Space Optimization
Given its branchy and compact nature, it is perfectly suited to the SOG (Sea of Green) technique. It doesn’t require great heights, making it ideal for low tents or shelving. With a flowering period of approximately 60 days, it guarantees rapid turnover with a yield that can reach up to 625g/m² if the temperature (above 10°C) and light are correct.
Outdoor Cultivation: Record Harvests in Mid-September
Outdoors, Master Kush Grand shows its true productive strength. Being a plant native to mountainous climates, it is naturally robust and resistant.
Harvest takes place in the first half of September, perfect timing to avoid mold caused by autumn rains. If planted in open soil and with good sun exposure, it can reach a record yield of 1.5kg per plant. It is one of the few pure Indicas that can produce such massive volumes while remaining medium-sized, concentrating all its energy into dense, very heavy flowers.
Terpene Profile: Earth, Spices, and Incense
The flavor of Master Kush Grand is an olfactory journey to Central Asia. Don’t wait! Enjoy the sweet or sour notes of modern hybrids.
- Aroma: Earthy and deep, with notes of damp earth and undergrowth.
- Taste: On the exhale, the smoke is dense and “ancient,” with clear references to Indian spices and a light touch of incense. The finish features a subtle hint of citrus that lightens the smoke.
It’s a classic profile, beloved by those seeking the taste of traditional hashish and musky aromas.
Effects: Indica Potency and Medicinal Value
With a THC content ranging between 20% and 25%, the effect is powerful and comes on almost immediately.
- Physical: A total relaxation that spreads throughout the body, releasing muscle tension and stiffness.
- Mental: Despite its potency, it’s not an anxiety-inducing high; instead, it leads to a state of deep calm and serenity.
- Therapeutic: It’s considered one of the best strains for combating chronic insomnia, physical pain, and stress. Its ability to induce sleep and stimulate the appetite makes it a must-have for medicinal users.
