Killer Kush F1 Fast Version by Sweet Seeds · Fast-Flowering OG Kush Hybrid · Feminized Cannabis Seeds

Killer Kush F1 Fast Version by Sweet Seeds is a high-octane, ultra-fast hybrid that brings the legendary OG Kush experience to impatient growers — delivering massive resin-covered buds in just 7 weeks of flowering.

Are you tired of waiting months for your Kush to ripen?

Most OG Kush phenotypes take their sweet time, stretching out flowering for 9–10 weeks or more. That’s a long wait when you’re chasing flavor, potency, and that classic stoney finish.

What happens when your Kush takes too long to finish?

Extended flowering means more light bills, higher risk of mold, pests, and detection — especially outdoors. You’re gambling with time, space, and energy, all for a strain that might underdeliver. Slow growers can drain your patience and your yields, leaving you with mediocre harvests and wasted effort.

Meet the fast-flowering powerhouse that respects your time

Killer Kush F1 Fast Version cuts the wait without cutting quality. This isn’t a compromised clone — it’s a precision-bred fusion of elite OG Kush and a robust 3rd-generation autoflowering indica line. The result? A plant that finishes flowering in just 7 weeks, packs up to 600 g/m² indoors, and explodes with citrus-diesel aroma and heavy resin.

Step-by-step growing guide

1. Germinate seeds in a moist paper towel or starter cube at 22–25 °C
2. Transplant to a 3–5 L pot once roots emerge; use well-aerated soil
3. Provide 18/6 light cycle indoors or plant outdoors after last frost
4. Switch to flowering automatically — no photoperiod change needed
5. Monitor trichomes: harvest when mostly milky with some amber for balanced effect
6. Flush plants 7–10 days before harvest to improve taste
7. Dry buds at 18–20 °C and 50–60% RH for 10–14 days, then cure for 2–4 weeks

Frequently Asked Questions

Is Killer Kush F1 Fast Version really ready in 7 weeks?

Yes — under optimal conditions, flowering takes just 7 weeks. Some phenotypes may need up to 8 weeks for full maturity, especially outdoors. Always check trichomes for the best timing.

Can I grow this strain outdoors in a colder climate?

Absolutely. Its fast finish makes it perfect for regions with short summers. Harvest by early September before heavy rains and cold set in.

Does this strain need a lot of nutrients?

No — it’s efficient and doesn’t require heavy feeding. Over-fertilizing can damage flavor. Use a balanced organic mix and consider Complete Mini Starter Pack Biobizz for steady growth.

How strong is the smell during flowering?

Very strong — this Kush announces itself. If growing indoors, use a carbon filter like those in our Grow Shop to stay discreet.

Personal Experience of Pevgrow’s CEO (Alan)

I grew Killer Kush F1 Fast Version last season in my 1.2 x 1.2 m tent with a 600W LED. I started with 3 seeds, all of which popped fast — typical Sweet Seeds quality. I used a 11 L final pot and went organic with Biobizz nutrients. The stretch was moderate — about 50% increase — and the plants filled the space evenly. What blew me away was the resin production: by week 6, the buds were already frosty. I harvested at week 7, dried slowly, and cured for 3 weeks. The high is crushing in the best way — full-body relaxation with a clear head buzz at the start. Flavor is top-tier: lemon fuel with a creamy finish. If you want OG power without the wait, this is your strain. My only tip? Don’t skip the flush — it makes the smoke way smoother.
