New York 47 Feminized Cannabis Seeds by World Of Seeds

New York 47 is a feminized cannabis seed variety from World Of Seeds that crosses two legendary genetics — AK-47 and New York Diesel — into a single powerhouse plant with up to 20% THC. The 60% Sativa / 40% Indica split gives you the best of both worlds: large, resin-caked flower clusters with a lemony, fuel-soaked aroma that fills the room (and then some). If you want serious yields without a steep learning curve, this is where you start.

Why New York 47 Cannabis Seeds Deserve a Spot in Your Collection

Two parent strains that need no introduction. AK-47 has been winning Cannabis Cup awards since the mid-'90s, and New York Diesel brought that unmistakable fuel-and-citrus profile to coffeeshop menus across Amsterdam. World Of Seeds took both and created something that genuinely delivers on the hype — not just in potency, but in how forgiving she is to grow.

We've seen growers pick this one as their second or third run and come back grinning. The medium mould resistance and high pest resistance mean she doesn't punish small mistakes the way some diva strains do. That said, the one thing you absolutely cannot ignore is the smell. We're not talking "a bit pungent." We're talking your entire flat smells like a petrol station crossed with a lemon grove. Carbon filters aren't optional here — they're a requirement unless you want your neighbours asking questions.

The 40% Indica genetics show up clearly in the plant structure: compact, dense flower clusters coated in a thick layer of sticky resin, with trichomes reaching out to cover even the surrounding leaves. If you've grown pure Sativas before and found them lanky and unmanageable, New York 47 is a welcome change. She's still got that Sativa stretch — expect a 200% height increase after flipping to flower — but the buds pack on weight like an Indica.

New York 47 Yield and Growing Specifications

New York 47 feminized seeds produce plants capable of 350–450 g/m² indoors and 350–600 g per plant outdoors, with flowering wrapping up in roughly 10 weeks. Here are the numbers that matter:

Some competing seed banks list outdoor yields as high as 800 g per plant for this strain. The World Of Seeds data we work from puts it at 350–600 g, which is the more conservative and honest figure. Conditions matter — climate, soil, light hours, and feeding schedule all shift the final number. We'd rather you be pleasantly surprised than disappointed.

New York 47 Aroma and Flavour Profile

Open a jar of properly cured New York 47 and the first thing that hits you is fuel. Not subtle, not "hints of." Full-on diesel, like someone spilled premium unleaded on a bag of lemons. There's a citrus sharpness underneath — bright, almost acidic — that cuts through the heavy fuel notes and lingers on the palate. The terpene profile leans heavily into limonene and myrcene territory, which explains both the lemony zing and the thick, resinous body.

This is the strain that will out your grow room to anyone within a 20-metre radius if you don't invest in proper carbon filtration. We cannot stress this enough. Even during the vegetative phase she's pungent, and once flowering kicks in, the smell intensifies dramatically. If you're growing in a tent inside a shared building, a quality carbon filter and sealed ducting are non-negotiable.

How to Grow New York 47 Feminized Seeds

1. Germinate your New York 47 seeds using the paper towel method or directly in a starter plug. Keep temperatures between 22–26°C and maintain high humidity (around 70%) until the taproot emerges — typically within 48–72 hours.
2. Transplant seedlings into their growing medium once the first set of true leaves appears. She performs well in soil, coco coir, or hydroponic setups. Start with a mild nutrient solution at about 25% strength.
3. During the vegetative phase, keep your light cycle at 18/6. She responds well to LST (low-stress training) and topping — both help manage the significant stretch that comes later. Plan your canopy height carefully: she'll triple in size after the flip.
4. Switch to a 12/12 light cycle to trigger flowering. This is when the 200% height increase kicks in, so if you're working in a tent, make sure you've got headroom or have trained her aggressively during veg. Flowering takes approximately 10 weeks.
5. Install a carbon filter before flowering begins — not after you notice the smell. By the time the diesel aroma is obvious, it's already been leaking for days. Run negative pressure in your tent to pull all air through the filter.
6. Feed bloom nutrients according to your chosen schedule, increasing phosphorus and potassium as the buds develop. The resin production on New York 47 is heavy, so she'll appreciate a good feed without being overly sensitive to nute burn.
7. Harvest when trichomes shift from clear to milky-white with around 10–20% amber, depending on whether you prefer a more cerebral or body-heavy effect. Dry slowly in a dark room at 18–21°C with 55–60% humidity for 7–10 days, then cure in glass jars for at least two weeks.

New York 47 vs AK-47 vs New York Diesel — Comparing the Family

Since New York 47 is the offspring of both AK-47 and New York Diesel, growers often wonder how she stacks up against her parents. Here's a straightforward comparison:

AK-47 finishes faster and is arguably even easier to grow, but the flavour profile is milder — more earthy and sweet, less in-your-face. New York Diesel brings the diesel terps and a slightly longer flowering time. New York 47 sits right in the middle: she inherits the fuel-forward flavour from her Diesel parent, the robust growth pattern from AK-47, and adds her own twist with that sharp lemon note. If you've grown either parent and enjoyed it, this hybrid is the natural next step.

Honest Limitations — What to Watch Out For

No strain is flawless, and New York 47 has a couple of things you should know before you commit. First, the stretch. A 200% height increase after flipping to flower is significant. In a 160 cm tent, that means your plant needs to be no taller than about 50 cm when you switch to 12/12, or you'll be fighting for headroom. Topping and LST during veg aren't just nice-to-haves — they're practically mandatory for indoor growers with limited vertical space.

Second, the mould resistance is rated as medium. She handles pests well, but in high-humidity environments towards the end of flowering, those dense, resin-heavy buds can trap moisture. Keep your RH below 50% in the final two weeks and make sure airflow around the canopy is solid. A small oscillating fan pointed at the lower canopy does wonders.

Third — and we'll say it one more time — the smell. This is not a stealth strain. If discretion matters, budget for a proper carbon filter setup from day one. We've had customers come back saying they underestimated this, and by week six of flower, their entire house smelled like a garage forecourt. Don't be that grower.

Cannabis Research and THC — What the Science Says

New York 47's 20% THC content puts her firmly in the upper range of potency. According to a study published in PMC, researchers have investigated THC content across different cannabis types, noting significant variation between drug-type and fibre-type cannabis seeds (Cannabis sativa (Hemp) Seeds, PMC5665515). For context, the traditional use of cannabis for analgesia is well-documented: according to a review in PMC, "for thousands of years, the cannabis plant has been utilised in traditional remedies," with cannabis-induced analgesia being one of the most commonly cited reasons for use (Cannabis: A Toxin-Producing Plant with Potential Therapeutic Uses, PMC7915118).

Research also suggests that the distinction between Sativa-dominant and Indica-dominant varieties may influence user-reported effects. According to a web survey of medical cannabis users cited in PMC, respondents discriminated between Cannabis sativa and Cannabis indica effects in their self-reported experiences (Use Patterns, Beliefs, Experiences, PMC8517044). With New York 47's 60/40 Sativa-Indica split, the Indica genetics contribute noticeably to the overall character — something World Of Seeds specifically highlights in their breeding notes.

A note on safety: cannabis can interact with certain medications, including blood thinners and antidepressants, potentially leading to unintended side effects or reduced effectiveness of these medications. If you're taking any prescription medication, speak with your doctor before use.
