00 Kush Fast Feminized Seeds – 22% THC Powerhouse from 00 Seeds · High-Yielding & Fast-Flowering Indoor/Outdoor Strain

00 Kush Fast feminized seeds pack a serious 22% THC punch and deliver heavy harvests in record time, making them a top choice for growers who want fast, high-quality results in any setup.

Ever feel stuck choosing between speed and potency? Most fast strains leave you with weak effects or tiny yields. You either rush the grow and sacrifice quality, or wait forever just to get something decent. It’s exhausting.

And when you’re juggling space, light cycles, or outdoor timing, a strain that drags on for months just doesn’t fit. You end up stressed, overcompensating with nutrients, or stuck with mediocre buds that don’t hit right. The compromise is real — until now.

00 Kush Fast flips the script. This isn’t just another fast strain — it’s a high-THC powerhouse that finishes in 45–50 days indoors and hits harvest by early October outdoors. You get dense, resinous flowers with a knockout effect, all without the long wait. Whether you're running tight indoor cycles or prepping for a clean outdoor finish, this strain adapts and delivers.

Indoor Growing Performance

Indoors, 00 Kush Fast shines with compact control and explosive yields. It stays manageable at 0.85–0.95 m (2.79–3.12 ft), perfect for stealth grows or SOG setups, yet still packs a punch with 350–450 g/m². The flowering time of just 45–50 days means you can run multiple harvests per year without sacrificing quality. Pair it with a quality soil mix like Bloombastic Soil Box ATA for maximum resin production and flavor depth.

Outdoor Resilience and Harvest Timing

Outdoors, this strain stretches into a towering 1.80–2.20 m (5.91–7.22 ft) plant, ready for harvest between October 1st and 10th. Its sturdy structure handles wind and mild humidity, and its fast finish helps avoid late-season mold. If you're growing in a Mediterranean or temperate climate, 00 Kush Fast gives you time to recover between seasons — no more racing against autumn rains.

How to grow 00 Kush Fast seeds

Get the most out of your 00 Kush Fast plants with this expert-backed grow guide tailored to its fast, high-yielding nature.

Quick overview: Feminized, Indica-dominant hybrid from 00 Seeds. 45–50 day flowering, low to medium difficulty. Ideal for indoor SOG or outdoor finishing in temperate climates.

Safe start: Germinate seeds in a moist, dark environment at 22–25 °C. Transplant carefully once the taproot is 1 cm long. For stronger starts, Plagron Hydro Roots boosts early root development and reduces shock.

Stable seedling: Keep humidity at 60–70% and provide gentle light. Water lightly and ensure excellent drainage. Introduce beneficial microbes like Bactofil bacillus and bacteria stimulate roots | Agrobacterias to enhance nutrient uptake and resilience.

Directed growth: Use 18/6 light cycle to build strong structure. Train with LST to maximize light exposure. Keep pots between 11–20 L depending on space. Avoid topping — this strain flowers fast and won’t recover well from stress.

Efficient flowering: Switch to 12/12 to trigger bloom. Maintain RH at 40–50% to prevent mold. Support heavy colas with stakes. Boost resin and density with a flowering stimulant like Radical Flower during peak bloom.

Harvest and refinement: Harvest when trichomes are mostly milky with some amber for a balanced high. Flush 7–10 days before harvest. Dry slowly at 18–22 °C and 50–60% RH, then cure for 2–4 weeks to enhance flavor and smoothness.

Personal Experience of Pevgrow’s CEO (Alan)

I grew 00 Kush Fast in my 1.20 m² (12.92 ft²) tent with a 600W LED, and I was blown away. From seed to harvest in 50 days — and I pulled 420 g (14.82 oz) off just four plants. The buds were rock-hard, covered in trichomes, and smelled like a gas station with a hint of sweet pine. I didn’t top any, just used LST to spread the canopy, and it worked perfectly. The high hits fast — cerebral and energizing at first, then melts into full-body relaxation. I’ve smoked it solo after work and shared it at weekend sessions, and every time, it gets compliments. If you want fast, potent, and reliable, this one’s a no-brainer.
