Kosher Kush

Kosher Kush Cannabis Seeds by Garden of Green

Kosher Kush is a 100% indica cannabis seed strain from Garden of Green, descended from OG Kush and packing up to 27% THC. It's a heavy-hitter that locks you to the sofa after raiding your fridge — the kind of old-school indica that reminds you why Kush genetics earned their reputation in the first place. If you want dense, resinous buds and a proper body stone, this is the one to grow.

Why Kosher Kush Seeds Deserve a Spot in Your Grow Room

There are a lot of indica seeds floating around, and most of them promise the same thing: big yields, strong stone, easy grow. Kosher Kush actually delivers on all three, which is rarer than you'd think. Garden of Green took OG Kush genetics and refined them into a strain that's vigorous from seed, produces tight internodal spacing, and finishes with buds so caked in trichomes they look frosted.

The THC content — up to 27% — puts Kosher Kush firmly in the heavy category. This isn't a casual afternoon smoke. It's a proper night-time indica that starts behind the eyes and works its way through your entire body until you're melted into whatever surface you're sitting on. Your appetite will spike hard, so stock the fridge before you light up. According to a study examining patient-reported strain preferences (PMC6275121), Kosher Kush was specifically mentioned by users in the context of pain relief — though we'd stress that cannabis research is still catching up with anecdotal experience.

The honest limitation? Kosher Kush stretches. A lot. When it flips to flowering, expect it to nearly double in height. If you're growing in a tent with limited headroom, you'll need to train it early or flip sooner than you might with a stockier indica. Ignore this and you'll be fighting your ceiling by week four of flower. We've seen growers get caught out by this more than once — it grows like an indica but stretches like it has sativa in its family tree.

Growing Kosher Kush: What to Expect From Seed to Harvest

Kosher Kush is a grower-friendly strain that rewards basic attention with generous harvests. Here's what the numbers look like across both environments.

Indoors, you're looking at 8–9 weeks of flowering before those dense colas are ready to chop. The short internodal spacing means buds stack tight along the branches, and the resin production is heavy enough that trimming becomes a sticky affair — keep your scissors clean and your patience ready. Up to 650g/m² is achievable with proper lighting and feeding, which is a strong return for the flowering time.

Outdoors is where Kosher Kush really flexes. Given enough root space, sunshine, and an attentive hand, a single plant can push up to 750g. Harvest falls in early to mid-October, so you'll want to keep an eye on weather if you're growing in northern Europe — late rain and dense buds are not friends. Good airflow around the canopy is your best defence against mould.

One practical tip from experienced growers: Kosher Kush seems to be a magnesium-hungry strain. Give it a boost of magnesium once during vegetative growth and again at the start of flowering. It's a small detail, but it can prevent those yellowing lower leaves that creep up on you mid-bloom.

Kosher Kush Aroma and Flavour: Old-School Kush Character

Kosher Kush smells exactly how a Kush should — intense, pungent, and unmistakably earthy with sharp pine cutting through. There's nothing subtle about it. If you're growing indoors, a carbon filter isn't optional; your neighbours will know what you're up to within the first week of flower.

On the inhale, you get woody, almost forest-floor notes. The exhale brings citrus and herbs forward, with a lingering sweetness that rounds out the profile. It's the kind of smoke that tastes richer through a clean glass piece than through a paper — the terpene profile is complex enough to reward a slower session. The dominant terpenes are myrcene, limonene, and caryophyllene, which together create that classic earthy-citrus-spice combination that Kush lovers chase.

Compared to something like the original OG Kush, Kosher Kush leans heavier on the pine and earth side while dialling back the fuel notes. If you like your Kush flavours raw and unpolished rather than fruity or sweet, this is your strain.

Kosher Kush Effects: A Proper Night-Time Indica

At up to 27% THC, Kosher Kush doesn't mess about. The stone is physical, heavy, and deeply relaxing. It starts with a wave of warmth behind the eyes, then spreads through the body over 20–30 minutes until you're thoroughly planted on the sofa. Appetite stimulation is strong — the munchies hit hard and they hit fast, so have food ready before you sit down.

This is not a daytime strain. It's the one you reach for after everything else is done — dishes washed, emails answered, responsibilities handled. According to research examining patient-reported cannabis strain effects (PMC6275121), Kosher Kush was specifically noted by users in relation to pain management. A separate study (PMC6204402) documented that common side effects reported by cannabis users included dry mouth and dry eyes, which are worth keeping in mind — have water nearby.

If you're newer to high-THC strains, approach Kosher Kush with respect. A single hit might be enough to gauge where you stand before committing to a full session. At 27% THC, even experienced smokers notice the potency.

How to Grow Kosher Kush Seeds

1. Germinate your Kosher Kush seeds using the paper towel method or directly in a starter plug. Keep the environment warm (22–25°C) and moist until taproots emerge — typically within 2–4 days.
2. Transplant seedlings into their growing medium once taproots are 1–2cm long. Kosher Kush responds well to soil and coco coir alike.
3. During vegetative growth, give plants a magnesium supplement to prevent deficiency later in the cycle. Keep humidity around 60–70% and temperatures between 20–28°C.
4. If growing indoors, consider topping or LST (low-stress training) early to manage the considerable stretch that comes when you flip to 12/12. This strain can nearly double in height during the flowering transition.
5. Switch to a 12/12 light cycle to trigger flowering. Expect 8–9 weeks before harvest. Lower humidity to 40–50% during late flower to protect those dense, resinous buds from mould.
6. Harvest when trichomes are mostly cloudy with some amber — this is where you'll get the heaviest body stone. Outdoor growers should aim for early to mid-October, weather permitting.
7. Dry in a dark, well-ventilated space at 18–22°C for 7–10 days, then cure in airtight jars for at least 2 weeks. The earthy, piney terpene profile develops significantly during a proper cure.
