KO Kush Feminized Seeds · Heavyweight Seeds · Indica-Dominant Powerhouse with Knockout Effects

KO Kush feminized seeds from Heavyweight Seeds are your ticket to cultivating a true indica-dominant champion, a strain designed to deliver a powerful, sedative high alongside impressively heavy harvests. This is the plant for growers who want maximum impact with minimal fuss.

Ever feel like your homegrown stash runs out too fast, or that the high just doesn't hit that deep, satisfying level of relaxation? You're not alone. Many growers chase big yields but end up with lanky, difficult-to-manage plants or harvests that look great but lack that classic, heavy Kush punch. This frustration leaves you constantly searching for that perfect balance of potency, yield, and grower-friendly traits.

KO Kush is the solution bred specifically to end that search. By crossing the legendary Afghani, Hash Plant, and Northern Lights, Heavyweight Seeds created a plant that grows outwards, not upwards, forming a dense, bushy structure absolutely laden with resinous buds. Its high bud-to-leaf ratio makes trimming a breeze, and its solid mold resistance means you can grow with confidence, even if your climate isn't perfect. This strain doesn't just promise a heavy yield; it delivers a heavy, full-body stone that's perfect for unwinding at the end of the day.

What to Expect Your First Grow

Your first run with KO Kush will likely surprise you with its vigor and straightforward nature. You'll see a plant that stays relatively compact indoors, perfect for tents or spaces with height restrictions. It branches out generously, creating multiple cola sites without much training needed. The aroma during flowering is a classic, earthy Kush with spicy, piney undertones that will intensify as harvest approaches. Don't be alarmed by the thick, sticky resin production—it's a sign you're on the right track.

Common Mistakes and How to Avoid Them

• Overwatering: Its indica heritage means it prefers a drier root zone. Let the top layer of soil dry out between waterings.
• Overfeeding: It's not a heavy feeder. Start with half-strength nutrients and increase only if you see signs of hunger.
• Insufficient Airflow: While mold-resistant, its dense buds need good circulation. Ensure fans are moving air around the canopy, not just blowing directly on it.
• Harvesting Too Early: Patience pays. Wait for the trichomes to turn mostly milky with some amber for that classic, couch-locking indica effect.
• Ignoring Low-Stress Training (LST): Even though it's bushy, gentle LST can open up the canopy for even better light penetration and bigger buds.

How to Dial in Your Perfect Harvest

1. Start Simple: Use a quality, well-aerated substrate like BioBizz Light Mix to give roots the perfect environment.
2. Monitor One Variable: When adjusting nutrients, change only one element (e.g., PK booster) at a time and observe the plant's response over 3-4 days.
3. Keep a Log: Note feeding schedules, pH levels, and any changes in plant appearance. This is invaluable for refining your technique.
4. Tailor the High: For a more energetic effect, harvest when trichomes are mostly cloudy. For full sedation, wait until 20-30% turn amber.
5. Perfect the Dry & Cure: Dry slowly at 18-22°C (64-72°F) and 50-60% RH for 10-14 days, then cure in jars, burping daily for 2-4 weeks for sublime flavor.

Frequently Asked Questions

How long does it take from seed to harvest?

Indoors, with an 8-week flowering period and a typical 4-5 week vegetative phase, you're looking at roughly 12-13 weeks total. Outdoors in the Northern Hemisphere, plants are ready by late September.

Is KO Kush good for beginners?

Absolutely. Its resilience to mold, manageable size, and straightforward nutrient needs make it an excellent choice for novice growers looking for a high-yielding, potent strain without extreme technical demands.

What's the best way to maximize yield with KO Kush?

Utilize its natural bushiness with Low-Stress Training (LST) to expose more bud sites to light. Ensure consistent feeding without overdoing it, and consider adding a bloom booster like PK 13/14 during the peak flowering weeks to support bud development.

How strong is the smell during growth?

The smell is moderate to strong, especially in late flowering, with classic earthy, spicy Kush notes. Using a carbon filter in your indoor setup is highly recommended for discretion.

Personal Experience of Pevgrow’s CEO (Alan)

I've run KO Kush several times, both in our test tents and at home, and it's become a personal favorite for reliable, heavy-handed relaxation. What strikes me first is how it lives up to its name in the grow room—it's a stocky, no-nonsense plant that focuses energy on building dense, rock-hard buds rather than stretching. I found it performed exceptionally well in a simple soil setup with BioBizz Light Mix, requiring less frequent feeding than some other 'heavyweight' strains. The high is exactly what I look for after a long day: a warm, pressure-like sensation that starts behind the eyes and spreads through the body, melting away tension without being overly cerebral or paranoid. The flavor is old-school Kush through and through—earthy, hash-like, with a peppery finish that reminds me of the classic Afghani landraces. My pro-tip? Don't rush the flush. Giving it a good 10-day plain water rinse really lets those spicy, clean flavors shine through in the final smoke.
