How to Grow Kosher Kush
Kosher Kush is a multi-award-winning indica classic, a prized phenotype of OG Kush. It is a 70/30 indica-dominant feminized plant with an approachable, medium 18-22% THC, a deep earthy, piney and pungent flavor, and a happy, relaxed, talkative effect. Resinous, flavorful and genuinely easy to grow, it is a rewarding way to grow a decorated OG classic.
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, resinous, pungent character of OG Kush that earned Kosher Kush a string of Cannabis Cup and Spannabis awards, for a flavorful, relaxing and reliable grow.

Growing a Feminized Strain
Kosher 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.
Kosher Kush is a tall grower, reaching up to around 2 m with a classic, branchy OG structure and plenty of stretch, so height management matters. It responds well to topping and low-stress training, and a ScrOG or an open canopy helps spread the light across its long branches. Veg it to the height you want, flip it, and it will finish dense, resinous and pungent in 8 to 10 weeks of flower.
Climate and Where to Grow It
Kosher Kush does best in a warm, tropical or Mediterranean-style climate with plenty of sun, steady warmth and good airflow. Even warmth and a dry finish suit its dense, resinous buds and help them mature clean, while its OG heritage makes it a strong, vigorous plant. Outdoors in the Northern Hemisphere it is ready to harvest around October, after a full season of sun.
It performs well indoors and out. Indoors it returns a solid 450 g/m² in a well-managed tent, especially when its height is trained in, while outdoors each plant gives a generous 600 g with full sun, space and support. As a tall, indica-dominant plant of around 2 m it does stretch, so the main job is managing that height and keeping the canopy open so light and air reach the lower buds.
Keep humidity sensible through flowering to protect those dense, resinous colas: around 55-60% in veg, nearer 40% as the flowers fill out, and lower toward harvest. A pungent, resinous OG 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), which this warm-climate plant enjoys.
Feeding Schedule (EC Guide)
Kosher 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 Kosher Kush to a 12/12 light cycle it flowers in about 8 to 10 weeks, filling out with dense, resinous, trichome-coated buds on a tall, branchy OG frame. It keeps the frosty, pungent structure that made it a repeat Cannabis Cup and Spannabis winner. Outdoors in the Northern Hemisphere it is ready to harvest around October, after a full season of sun.
Yields are solid: around 450 g/m² indoors and a generous 600 g per plant outdoors with good sun, space and support for its height. Train it early 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 most 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 OG, 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 deep earthy, piney and pungent notes and smooths the smoke, which matters on a classic OG like Kosher Kush where that rich, pungent character is the main attraction.
What to Do With Your Trim
Don’t bin the sugar leaves you remove while manicuring. Kosher 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-pungent concentrate run from material most growers would otherwise throw away.
Flavor and Terpenes
Kosher Kush has a deep, classic OG flavor: a rich, earthy base with a fresh piney lift and a strong, pungent, almost spicy edge, exactly the profile that made it famous. It is a smooth, earthy-and-piney smoke with a pungent kick, 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, pungent 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, pine and pungent character Kosher Kush is known for.
Effects and Best Use
With its approachable, medium 18-22% THC and heavily indica 70/30 make-up, Kosher Kush delivers a deep, 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 social sessions. Its medium potency keeps it approachable and easy to dose.
That happy, relaxed, talkative profile makes it a natural evening and social strain, ideal for winding down with friends while enjoying its pungent, earthy-and-piney flavor. The combination of a decorated OG pedigree, a classic indica effect and a resinous, flavorful finish is exactly why it stands out.
Common Problems and Pro Tips
The biggest thing to plan for with Kosher Kush is its height. It is a tall, stretchy OG, so start height management early: top it, use low-stress training, and run a ScrOG or an open canopy so light reaches the lower buds rather than letting it grow tall and leggy. An even canopy is what turns that stretch into long, productive colas.
Its dense, pungent OG buds mean humidity is the main risk late in flower, 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. Start seedlings gently to avoid transplant stress, then let its hardy OG genetics do the rest.
As a pro tip, protect the pungent terpenes that carry its flavor: go gentle on the nutrients, finish with a proper plain-water flush, and give it a full three to four week cure. Harvest when most trichomes are cloudy for a deeply relaxing, medium-strength result with the rich, earthy-and-pungent taste this award-winner is prized for.
FAQ
Is Kosher Kush a feminized strain?
Yes. Kosher 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 Kosher Kush have?
Kosher Kush is a medium-THC strain, testing at around 18-22%, which gives an approachable effect rather than an overwhelming one.

That moderate potency makes it easy to dose and a good fit for newer growers and smokers alike.
How long does Kosher Kush take to flower?
Kosher 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. Because it is a tall, stretchy OG, giving it early training keeps it manageable and makes the most of its flowering stretch.
What does Kosher Kush taste like?
