Critical Poison Feminized Seeds by 00 Seeds – Fast-Flowering Indica Powerhouse for High Yields

Critical Poison feminized seeds from 00 Seeds offer a fast, high-yielding grow with brutal resin production and a relaxing indica punch—perfect for growers who want quality without the wait.

Are you tired of waiting months just to harvest?

Most indica-dominant strains keep you on edge for 9–10 weeks in flower, eating up time, electricity, and patience. And if you're growing in a tight space or unpredictable climate, a slow, stretchy plant can turn into a mold-prone, light-hogging headache.

By the time you finally trim, cure, and test your buds, you’ve already lost momentum. Worse? Mediocre yields and weak effects that don’t justify the effort.

Meet Critical Poison—a no-nonsense, fast-finishing powerhouse bred to deliver massive harvests in record time. With a flowering cycle of just 45–50 days indoors and up to 600 grams per square meter, this strain cuts the wait and maximizes your return. Its compact, conical structure makes it ideal for stealth grows, and the 19% THC ensures a deeply relaxing finish every time.

Enjoy faster harvests and heavier yields without compromising quality

Whether you're rotating crops or just hate waiting, Critical Poison gets you from seed to stash in under 10 weeks. Its rapid flowering and explosive resin production mean you’re not just saving time—you’re banking serious weight with every cycle. The buds are dense, frosty, and packed with a complex terpene profile that blends earthy depth with bright citrus sparks. It’s the kind of strain that makes your grow room smell like a forest after rain—rich, organic, and unmistakably potent.

How to grow Critical Poison for maximum resin and yield

Critical Poison thrives in controlled environments but adapts well outdoors, especially in Mediterranean or temperate climates. Its indica dominance means minimal stretch, so you can pack more plants per square meter without canopy chaos. Just remember: those heavy colas need support.

1. Start seeds in a moist paper towel or directly in small pots at 22–25 °C (71.6–77 °F) with 60–70% humidity.
2. Transplant to final pots of 11–20 L (2.90–5.28 gal) once roots emerge; use well-aerated soil or coco for best results.
3. Provide 18/6 light cycle during vegetative stage, then switch to 12/12 to trigger flowering.
4. Use low-stress training (LST) early to shape the plant and improve light penetration—avoid topping or aggressive pruning.
5. Monitor humidity closely; keep it at 40–50% during flowering to prevent mold, especially in dense bud sites.
6. In the last two weeks, flush with plain water to enhance flavor and smoothness before harvest.

Personal Experience of Pevgrow’s CEO (Alan)

I’ve grown dozens of indica strains, but Critical Poison stands out for its speed and consistency. I ran it in a 60x60 cm tent with a 600W LED, and it filled the space in just 4 weeks of veg. The flowering stretch was minimal—maybe 20 cm—so I didn’t need to worry about light burn. By week 7, the room smelled like a lemon grove after rain. I used a SCROG net to spread the canopy, and the yield was insane: 580 grams from just three plants. The high is pure relaxation—perfect after a long day. My only tip? Stake early. Those colas get heavy fast.
