How to Grow Master Kush
Master Kush is a legendary, heavily indica classic from Amsterdam, built on pure Hindu Kush and Skunk genetics. It is a 90/10 indica-dominant feminized plant with high 20-24% THC, a deep earthy and piney flavor, and a happy, relaxed, talkative effect. Hardy, resinous and genuinely easy to grow, it is one of the most rewarding indicas you can put in a tent or a sunny garden.
This is a feminized photoperiod strain, so every seed grows into a flowering female and you start flowering by switching the light cycle to 12/12, which lets you decide how big the plant gets before you flip it. It keeps the dense, trichome-coated buds and the earthy, hashy character of the original Master Kush, a strain prized for its heavy indica relaxation and its reliable, high-yielding grow.

Growing a Feminized Strain
Master Kush is a feminized photoperiod strain, so every seed grows into a flowering female and there is no sexing and no need to remove males. Because it flowers on the light cycle rather than on age, you control the timing: keep it under long 18/6 days to grow and build the frame you want, then switch to 12 hours of light and 12 of darkness to start flowering. That control is what lets you dial in the size and the yield.
Although Master Kush can reach up to 3.3 m outdoors with a full season and root room, indoors it stays naturally compact and bushy with very little stretch, which is exactly why it suits a Sea of Green (SOG) setup. Veg it to the height you want, flip it, and it will finish dense and resinous in 8 to 10 weeks of flower, rewarding a little canopy management with a heavy, trichome-rich harvest.
Climate and Where to Grow It
Master Kush does best in a temperate climate with warm, mild conditions, steady temperatures and good airflow. It is a hardy, resilient plant from Hindu Kush landrace stock, so it handles a range of conditions well, but even warmth and a dry finish suit its dense, resinous buds and help them mature clean. Outdoors in the Northern Hemisphere it is ready to harvest around October.
It performs strongly indoors and out. Indoors it returns a heavy 400-600 g/m² in a well-managed tent, especially in a SOG, while outdoors it can give a huge 800-1000 g per plant with full sun, space and a long season. As a sturdy, indica-dominant plant it is easy to manage, so the main job is keeping the canopy open so light and air reach the dense lower buds.
Keep humidity sensible through flowering to protect those chunky colas: around 55-60% in veg, nearer 40% as the flowers fill out, and lower toward harvest. A resinous indica like this can trap moisture inside its tight buds, so steady airflow keeps the finish clean. Aim for daytime temperatures around 68-80°F (20-27°C) with slightly cooler nights, which this temperate-climate plant enjoys.
Feeding Schedule (EC Guide)
Master Kush is a moderate feeder that responds well to steady, balanced nutrition. Build the feed up gradually through veg, push phosphorus and potassium once it is in flower to fuel those dense buds, then taper off for the final flush so the earthy, piney flavor comes through clean and the smoke finishes smooth. The ranges below are a starting guide; adjust to your water and medium.
| Stage | EC (mS/cm) | Notes |
|---|---|---|
| Seedling | 0.4-0.6 | Very light feed while roots establish |
| Vegetative | 0.8-1.2 | Raise nitrogen as the plant builds size |
| Early flower | 1.2-1.4 | Shift toward bloom nutrients (P and K) |
| Full flower | 1.4-1.6 | Peak bloom feed while the buds swell |
| Flush | 0.0-0.4 | Plain water for the final 1-2 weeks |
Flowering and Harvest
Once you switch Master Kush to a 12/12 light cycle it flowers in about 8 to 10 weeks, filling out with dense, chunky, trichome-coated buds on a sturdy indica frame. It keeps the compact, frosty structure and the earthy, hashy character the original is known for. Outdoors in the Northern Hemisphere it is ready to harvest around October, after a full season of sun.
Yields are heavy: around 400-600 g/m² indoors, especially in a SOG, and a huge 800-1000 g per plant outdoors with good sun and space. Keep the canopy open so the lower buds get light, feed it steadily through flower, and harvest when most of the trichomes have turned cloudy for the fullest earthy-and-piney flavor and the deepest relaxing effect.
Drying and Curing
Dry whole plants or branches in a dark room at around 60°F (15-18°C) and 55-60% humidity for 7-14 days, until the thin stems snap rather than bend. A slow, even dry matters with such a resinous indica, because its dense buds can stay damp in the middle while the outside dries, and a gentle dry protects both the aroma and the trichomes.
Then cure the trimmed buds in sealed jars, burping them daily for the first week and letting them settle for three to four weeks. A proper cure is what brings out the earthy, piney and hashy notes and smooths the smoke, which matters on a classic indica like Master Kush where that deep, kush-rich character is the main attraction.
What to Do With Your Trim
Don’t bin the sugar leaves you remove while manicuring. Master Kush is a resinous, trichome-rich plant, so its trim works especially well for dry sift, bubble hash or rosin. Its heavy resin makes that trim worth saving for a flavorful, earthy-and-hashy concentrate run from material most growers would otherwise throw away.
Flavor and Terpenes
Master Kush has a deep, classic kush flavor: a rich, earthy base with a fresh piney lift and a hashy, musky backbone, exactly the pungent profile the original is known for. It is a smooth, earthy-and-piney smoke with a woody edge, and a good cure really brings that character forward in the jar and on the inhale.
Its terpene profile shapes that character. Myrcene drives the deep, earthy and musky base, while alpha-pinene brings the fresh, piney lift. Caryophyllene adds a warm, peppery spice, and humulene rounds it out with an earthy, woody depth. Together these terpenes frame the earthy and pine character Master Kush is known for.
Effects and Best Use
With its high 20-24% THC and heavily indica 90/10 make-up, Master Kush delivers a potent, deeply relaxing experience. It is reported as happy, relaxed and talkative, pairing a heavy, settled body with an upbeat, chatty and cheerful head, so it is best suited to the evening and the end of the day. Its high potency makes it a strain to dose with a little respect.
That happy, relaxed, talkative profile makes it a natural evening and social strain, ideal for winding down with friends while enjoying its earthy-and-piney flavor. The combination of a hardy, high-yielding grow, a classic heavy indica effect and a resinous, flavorful finish is exactly why it stands out.
Common Problems and Pro Tips
The biggest thing to get right with Master Kush is managing its dense, chunky buds in late flower. Those tight colas can trap moisture, so keep the air moving, hold humidity down as the flowers fill out, and defoliate a few of the largest fan leaves in mid-flower so light and air reach the lower buds. A clean, dry finish is what protects such a resinous indica from problems in the final weeks.
Because it stays compact with very little stretch, Master Kush is a natural fit for a Sea of Green: run several smaller plants, flip them early, and let the even canopy fill the space rather than pushing one plant tall. Start seedlings gently to avoid transplant stress, then let its hardy Hindu Kush genetics do the rest, since this is a forgiving, beginner-friendly plant.
As a pro tip, feed it steadily but do not overdo the nutrients, and push bloom feed once the buds set to make the most of its heavy yield. Finish with a plain-water flush and a full three to four week cure, and harvest when most trichomes are cloudy for a deeply relaxing, high-strength result with a clean, earthy-and-piney flavor.
FAQ
Is Master Kush a feminized strain?
Yes. Master Kush is a feminized photoperiod strain, so every seed grows into a flowering female and there is no sexing and no males to remove. Because it flowers on the light cycle rather than on age, you veg it under long 18/6 days for as long as you like, then switch to 12/12 to start flowering, which lets you control its final size and yield.
How much THC does Master Kush have?
Master Kush is a high-THC strain, testing at around 20-24%, which places it firmly at the potent end of the scale. Combined with its heavily indica 90/10 genetics, the result is a deep, relaxing experience with a happy, talkative lift. Because the potency is high, it is worth dosing with a little respect, especially if you are newer to strong indicas.
How long does Master Kush take to flower?
Master Kush flowers in about 8 to 10 weeks once you switch it to a 12/12 light cycle indoors. Outdoors in the Northern Hemisphere it is ready to harvest around October, after a full season of sun. That relatively quick flowering for such a heavy yielder is a big part of why this indica classic has stayed popular with growers for decades.
What does Master Kush taste like?
Master Kush has a deep, earthy base with a fresh piney lift and a hashy, musky backbone. Myrcene drives the earthy depth, alpha-pinene the pine, caryophyllene a warm peppery spice, and humulene a woody edge. A proper three to four week cure really brings that pungent, earthy-and-piney kush character forward on the inhale and smooths the smoke.
How much does Master Kush yield?
Master Kush is a heavy producer, giving around 400-600 g/m² indoors, especially in a Sea of Green, and a huge 800-1000 g per plant outdoors with full sun and space. Results depend on light, pot size and canopy health, so keep an open canopy, feed it steadily through flower, and give it room so the dense buds develop fully.
Is Master Kush good for beginners?
Yes. Master Kush is a beginner-friendly plant: it is feminized so there is no sexing, it is hardy and forgiving thanks to its Hindu Kush landrace genetics, and its compact, low-stretch growth is easy to manage in a Sea of Green. The main thing to watch is airflow around its dense buds in late flower, which a little canopy management takes care of.
