King's Kush Autoflowering

King's Kush Autoflowering Cannabis Seeds

King's Kush Autoflowering is an autoflowering feminised cannabis seed from Greenhouse Seeds that delivers a heavy, creeping body effect in just 9 weeks from seed to harvest. Bred from King's Kush crossed with Ruderalis, this compact auto stays true to its photoperiod parent — same sweet grape flavour, same powerful relaxation, just faster and easier to grow. At up to 90cm tall and yielding around 600g/m², she punches well above her weight class for an autoflower.

Why King's Kush Autoflowering Deserves Your Grow Space

Here's the thing about autoflowering versions of classic strains — they often lose something in translation. The flavour gets diluted, the potency drops a notch, or the yield shrinks to the point where you wonder why you bothered. King's Kush Autoflowering from Greenhouse Seeds is one of the exceptions we'd actually recommend. The Ruderalis genetics do their job (triggering automatic flowering regardless of light schedule) without bulldozing the characteristics that made King's Kush popular in the first place.

The sweet grape taste and aroma come through clearly. Not faintly, not "if you squint." It's there on the inhale and it lingers. The effect builds slowly — a creeping body relaxation that starts mild and keeps stacking. We've seen newer growers underestimate this one because the onset is gradual. Give it 15–20 minutes before deciding you need more. That creeping quality is actually what makes her so good for evening use: you ease into it rather than getting hit all at once.

From a practical standpoint, 9 weeks from seed to chop is genuinely fast. You're looking at roughly 70–80g per plant, or up to 600g/m² if you pack them in. For a plant that tops out at 90cm with tight branching, those numbers are impressive. She won't take over your tent, she won't need complicated training, and she won't demand a specific light schedule switch. Plant, water, feed, harvest. That's the pitch, and she delivers on it.

How King's Kush Auto Compares to Other Greenhouse Autos

If you're browsing the Greenhouse Seeds autoflowering lineup, King's Kush Auto sits at the heavier, more physically relaxing end of the spectrum. She's not a daytime strain — that sweet grape flavour and creeping body effect are built for winding down, not gearing up. For something with more cerebral energy, look at a sativa-leaning auto instead. But if deep physical relaxation is what you're after, King's Kush Auto is one of the strongest options in the Greenhouse catalogue at this speed.

The honest limitation? She's compact. At 90cm max, there's not much room for error with nutrients or environmental stress — stunting an autoflower by even a few centimetres costs you proportionally more yield than it would on a 150cm photoperiod plant. Keep your pH dialled in (5.8–6.2 in hydro, 6.0–6.5 in soil), don't transplant her (start in the final pot), and avoid overwatering in the first two weeks. Autos don't give you recovery time.

How to Grow King's Kush Autoflowering Seeds

1. Germinate your King's Kush Autoflowering seeds using the paper towel method or directly in a small plug of moist coco or soil. Taproots typically appear within 24–72 hours.
2. Plant the germinated seed directly into its final container — 11 to 15 litres is the sweet spot. Autoflowers don't respond well to transplanting because any root disturbance during their short life cycle costs you growth time you can't get back.
3. Set your light schedule to 18/6 or 20/4 from day one and keep it there for the entire grow. King's Kush Auto doesn't need a 12/12 flip — she'll start flowering on her own around week 3–4.
4. Keep feeding light during the first two weeks. Seedlings don't need much, and overfeeding an auto early is one of the fastest ways to stunt her. Gradually increase nutrients as she enters pre-flower.
5. Watch for the stretch around weeks 3–5 as she transitions to flower. King's Kush Auto stays compact with minimal branching, so you shouldn't need heavy training. A bit of gentle LST (low stress training) in the first three weeks can open up the canopy if you want to maximise light penetration.
6. Flush with plain water for the final 7–10 days before harvest. Trichomes should shift from clear to milky with some amber — harvest when roughly 70–80% are milky for that classic heavy Kush effect.
7. Dry in a dark room at 18–20°C and 55–60% humidity for 7–10 days, then cure in glass jars for at least two weeks. The grape sweetness really develops during a proper cure.
