Critical Poison Fast Version Feminized Seeds | 00 Seeds · Fast-Flowering Indica-Dominant Strain for High Yields

Critical Poison Fast Version feminized seeds from 00 Seeds deliver big harvests in record time, with a powerful 19% THC and a fast 35–40 day indoor flowering cycle—perfect for growers who want quality without the wait.

Are you tired of waiting months just to harvest?

Most indica-dominant strains take their sweet time, stretching out flowering for weeks on end. You’re left babysitting plants, stressing over mold, and watching your window to harvest shrink with every passing day—especially if you're growing outdoors where autumn rains loom.

What happens when slow growth meets bad weather?

You risk losing everything. Dense buds soak up humidity like sponges. One week of damp weather and boom—botrytis sets in. All that effort, all those nutrients, all that light—wasted. And if you’re in a cooler climate, you might not even make it to harvest before the cold shuts everything down.

Critical Poison Fast Version cuts the wait and slashes the risk

This isn’t just another fast strain—it’s a precision-engineered harvest accelerator. Bred from Skunk and a secret indica lineage, it finishes flowering up to two weeks earlier than standard Critical strains, letting you beat the rain and enjoy your stash sooner. With dense, resin-coated buds and a sweet lemon-citrus punch, it’s as flavorful as it is fast.

How Critical Poison Fast Version speeds up your grow

This strain turns impatience into an advantage. It doesn’t just flower faster—it grows smarter. Compact internodes mean better light penetration, while its vigorous start ensures strong root development from day one. You’ll spend less time managing stretch and more time watching buds swell with trichomes.

Simple steps to grow Critical Poison Fast Version in record time

Get from seed to harvest with minimal fuss and maximum results.

1. Start seeds in a moist, airy medium at 22–25 °C (71.6–77 °F).
2. Transplant once roots emerge (~1 cm) into a well-draining soil or coco mix.
3. Keep light cycles at 18/6 (vegetative) or 12/12 (flowering) depending on setup.
4. Use low-stress training (LST) early to control height and boost yields.
5. Harvest in just 35–40 days when trichomes turn milky to amber.

How to grow Critical Poison Fast Version for best results

Get the most out of this fast-finishing powerhouse with a simple, effective grow plan.

Quick overview: Feminized, indica-dominant, 35–40 day flowering, low to medium difficulty—ideal for indoor setups and outdoor grows in temperate to humid climates.

Safe start: Germinate with high humidity and stable temps. For a hassle-free start, Root Juice BioBizz speeds up rooting and reduces transplant stress.

• Use paper towel or soil poppers at 22–25 °C (71.6–77 °F)
• Keep RH at 60–70% until first leaves emerge
• Transplant gently when radicle is ~1 cm (0.4 in)
• Avoid overwatering in early stages
• Use airy, well-draining soil or coco

Directed growth: 18/6 light cycle; support early branching. In sustained growth, Canna Potassium 20% keeps leaves green and structure compact.

• Begin light feeding after 2–3 sets of true leaves
• Use LST to control height and increase light exposure
• Top plants if desired during early veg (not recommended for autos)
• Ensure good airflow to prevent humidity buildup
• Maintain pH 6.0–6.5 (soil) or 5.8–6.2 (coco)

Efficient flowering: Switch to 12/12; boost PK in mid-flower. At the end of flowering, Rezin (Finisher) Green Planet helps with density and a cleaner taste.

• Reduce nitrogen and increase phosphorus and potassium
• Lower RH to 40–50% to prevent mold
• Support heavy branches with stakes or netting
• Flush 7–10 days before harvest
• Harvest when 70–80% of trichomes are milky

Personal Experience of Pevgrow’s CEO (Alan)

I’ve grown a lot of fast strains, but Critical Poison Fast Version stands out. I used it last summer in my greenhouse when the forecast predicted early rain. I planted in late June, switched to 12/12 by mid-July, and harvested by mid-August—two weeks before the clouds rolled in. The buds were dense, sticky, and smelled like lemon candy. I didn’t need aggressive training—just a little LST to spread the canopy. I paired it with Rezin during flowering and got some of the heaviest yields I’ve seen in a sub-40-day strain. If you’re short on time or live where fall comes early, this one’s a no-brainer.

One tip: don’t overfeed it. It grows fast, but it doesn’t need heavy nutrients from day one. Start light and ramp up. And if you’re outdoors, stake the main colas—they get heavy.
