OG Kush Auto by Fast Buds – High-Yielding Indica-Dominant Autoflower with Classic Kush Flavor

OG Kush Auto by Fast Buds redefines the classic kush experience in a compact, high-yielding autoflower that packs up to 23% THC and finishes in just 9 weeks. This is your ticket to heavy, resin-drenched buds without the grow stress.

Still stuck with weak, slow-growing autos?

Maybe you’ve tried other autoflowers that promised big yields but delivered wispy buds, weak effects, or took forever to finish. Or worse—your plants got hit by mold because they couldn’t handle a cool night or a humidity spike.

Why those strains leave you frustrated

Most autos sacrifice flavor and potency for speed. They’re either too stretchy, too sensitive, or just don’t taste like anything special. You end up with bland, low-THC buds that don’t deliver the couch-lock or creative spark you’re after. And if you're growing outdoors, a sudden cold snap or damp spell can ruin everything.

The OG Kush Auto upgrade: power, resilience, and flavor in one

Meet the autoflower that actually lives up to the OG name. OG Kush Auto combines the legendary genetics of the original with Fast Buds’ breeding precision to give you a plant that’s fast, frosty, and fiercely potent. It thrives in hot or cold climates, resists mold, and finishes with dense, trichome-covered colas that reek of pine, citrus, and diesel. This isn’t just another auto—it’s the real deal, optimized for real growers.

Why OG Kush Auto outperforms your current strain

Forget finicky photoperiods or autos that take 12 weeks. OG Kush Auto hits harvest in just 63–65 days from seed, with a compact, bushy structure that’s perfect for stealth grows or tight spaces. It handles temperature swings like a California native—because it is one. Whether you're in a humid basement or a dry desert, this plant adapts and delivers. And with up to 550 g/m² indoors and 140 g (4.94 oz) per plant outdoors, you’re not just saving time—you’re maximizing yield.

Key features you’ll notice from the very first grow

• Massive trichome coverage from week 6—buds look like they’ve been dipped in crystal.
• Explosive terpene profile: sharp pine, zesty citrus, and that unmistakable kush funk.
• Indica-dominant structure with short internodes—perfect for LST and maximizing light exposure.
• Stable genetics—every plant grows true to type, no duds.
• Resilient to cold and heat, making it ideal for unpredictable outdoor conditions.
• Finishes in just 9 weeks—no waiting around for payoff.
• High THC (up to 23%) with a long-lasting, full-body stone that melts stress away.

Who this strain is especially interesting for

OG Kush Auto is perfect for growers who want legendary flavor and knockout potency without the hassle. Whether you're a beginner looking for a forgiving, high-yielding auto or a veteran chasing that classic kush experience, this strain delivers.

• Growers in cold or variable climates who need a resilient plant.
• Those short on space but big on yield—thrives in 20 L pots.
• Connoisseurs who value terpene richness and authentic kush flavor.
• Medical users seeking strong body relaxation (not a medical claim).
• Anyone tired of autos that look or taste like nothing.

How to integrate it into your routine without overcomplicating things

Start with a 20 L fabric pot and quality soil—no need to overthink nutrients. Keep the light cycle at 20/4 or 18/6 and let it run its course. A little LST in week 2 helps open up the canopy, but don’t top it—this is an auto, after all. Water when the top inch feels dry, and you’re golden. It’s that simple.

Get the most out of your OG Kush Auto with this simple, expert-backed plan.

Quick overview

Fast Buds’ OG Kush Auto is a low-difficulty, high-reward indica-dominant auto. Ready in 9 weeks, it’s perfect for indoor tents or outdoor patios in any climate.

Safe start

Germinate with confidence and set roots early.

• Soak seeds 12–24h in pH-balanced water (6.0–6.5).
• Use starter cubes or direct soil for less stress.
• Keep humidity at 70% and temp at 22–25 °C.
• Transplant once the second set of true leaves appear.
• For faster rooting, try Clonex Rooting Hormone Gel.

Stable seedling

Build a strong foundation in the first 2 weeks.

• Use a well-aerated soil mix like All Mix Peat Free for optimal drainage.
• Water lightly—only when the top 2 cm of soil is dry.
• Start with low-intensity LED or CFL lighting.
• Introduce mild nutrients after week 2.
• Avoid overwatering—this is the #1 beginner mistake.

Directed growth

Maximize structure and light exposure.

• Move to final 20 L pot early—don’t re-pot later.
• Use 18–20h light cycle throughout the entire grow.
• Apply gentle LST to spread branches and improve airflow.
• Feed with balanced nutrients—this strain loves food.
• Keep temps at 22–26 °C and RH at 50–60%.

Efficient flowering

Boost resin and density in the final stretch.

• Switch to bloom nutrients at first pistils.
• Lower RH to 40–50% to prevent mold.
• Support heavy colas with stakes or a trellis net.
• Use P-Boost flowering stimulator during peak bloom for denser buds.
• Watch trichomes: harvest when milky with slight amber for balanced effect.

Harvest, drying and curing

Lock in flavor and potency.

• Flush with plain water 7–10 days before harvest.
• Cut branches and trim sugar leaves.
• Dry at 18–20 °C and 50–60% RH for 7–10 days.
• Cure in glass jars, burping daily for 2–4 weeks.
• Proper curing enhances smoothness and terpene retention.

Personal Experience of Pevgrow’s CEO (Alan)

I’ve grown a lot of OG Kush phenotypes over the years—some good, some underwhelming. But Fast Buds’ OG Kush Auto? That one surprised me. I ran four plants in my 1.2 m² tent with 600W LED, 20/4 light cycle, and 20 L pots. No fancy techniques—just solid basics. By week 6, the smell was insane—like walking through a pine forest after rain, with that classic kush punch. I did light LST early, and the plants responded perfectly. Yields were consistent: 520–540 g/m² after drying. The high? Deep, warm, and long-lasting—exactly what I want after a long day. I’ve recommended it to friends who want potency without the grow stress. If you’re looking for a no-nonsense, high-THC auto that tastes like the real thing, this is it.
