Before Growing with Killer Kush Auto

You’re prepping your tent, checking lights, and wondering if this auto will actually stretch or stay manageable. Most autos either vanish into the soil or turn into lanky monsters. You need something that fits your space, grows predictably, and doesn’t demand constant attention.

• Start with a final pot of 18–27 L to avoid transplant stress
• Use a well-aerated soil mix with perlite for root health
• Set your light to 18–20 hours daily—no changes needed
• Keep temperatures at 22–26 °C during growth
• Monitor pH at 6.0–6.5 for soil or 5.8–6.2 for coco

During Cultivation: Fast, Furious, and Frosty

Killer Kush Auto shoots up fast in the first three weeks, then locks into flowering with a burst of pistils. The stretch is moderate, and the branching is tight—perfect for SCROG or solo grows. By week 4, the aroma kicks in: sweet, sour, and unmistakably OG. By week 6, trichomes start clouding over, and by week 8, they’re milky-white with amber hints—ready to cut.

It handles heat and pests well, making it ideal for Mediterranean or temperate climates. Indoors, it stays compact at 60–100 cm (23.62–39.37 in), so even in tight spaces, you get big yields. For sustained growth, Sweet Seeds recommends clean airflow and consistent watering—no overfeeding.

After Harvest: Dense Buds, Deep Relaxation

Once dried and cured, the buds are rock-hard, jet-black in spots, and coated in resin. The effect? A wave of mental clarity followed by deep physical relaxation—ideal for evening use. You’ll notice reduced stress, enhanced creativity, and better sleep, all from a strain that asked for almost nothing in return.

Minimal trimming is needed thanks to low leaf production. For a cleaner finish, Bud Candy enhances sweetness and smoothness in the final weeks.

Frequently Asked Questions

How long does Killer Kush Auto take to grow?

From seed to harvest, Killer Kush Auto takes just 8 weeks. There’s no vegetative phase to manage—just plant, feed, and wait for the buds to ripen.

What size pot should I use for Killer Kush Auto?

Use a final pot of 18–27 L from the start. This prevents transplant stress and gives roots enough space to support heavy yields.

Does Killer Kush Auto smell strong during grow?

Yes, it has a medium to high odor, especially in late flowering. If discretion is key, use a carbon filter like those in our grow shop to control smells.

Can I top or prune Killer Kush Auto?

No—topping or aggressive pruning can severely stunt autoflowers. Use low-stress techniques like LST instead to shape the plant.

What’s the best way to increase yield?

Use a 20-hour light cycle, a 27 L pot, and a PK booster in late flowering. Combine that with proper LST and you’ll hit the upper end of the yield range.

Personal Experience of Pevgrow’s CEO (Alan)

I’ve grown a lot of autos, but Killer Kush Auto stands out. I planted four seeds in 20 L pots with BioBizz Allmix, and by day 25, they were already showing pistils. I kept them under a 400W HPS with 18/6 light—wait, no, 20/4, because autos love light. By week 6, the smell was unreal: sweet diesel with a citrus punch. I used Bud Candy in the last three weeks, and it made the smoke buttery smooth. Harvest was on day 56—slightly early for a more energetic high. Dried slowly, cured for three weeks. The buds were dense, dark, and sticky as hell. One joint had me relaxed but alert, perfect for unwinding after work. If you want OG Kush power without the wait, this is it. My only tip? Don’t overwater—let the soil dry between waterings. And skip the topping—just guide it with LST. Killer Kush Auto isn’t just fast—it’s reliable.
