Ever feel like growing top-shelf cannabis is a complex puzzle with too many moving parts? You juggle light schedules, worry about male plants, and wait months only to be disappointed by a modest yield. It's frustrating, time-consuming, and can kill your motivation before you even start. Big Bang Autoflowering shatters that complexity. It's the autoflowering evolution of a pharmacy-grade strain, designed for maximum output with minimal input. No more guessing games with light cycles or stressing over pollination—just consistent, robust growth from seed to harvest in as little as 6-7 weeks.

Before You Grow: Setting Up for Success

Getting started with Big Bang Auto is refreshingly simple. Its autoflowering nature means you don't need a separate veg and flower room, making it ideal for a single-tent setup or a discreet outdoor spot.

• Choose Your Final Pot Early: Autoflowers hate root disturbance. Transplant your germinated seed directly into its final pot, ideally 18–27 L (4.8–7.1 gal), to avoid stunting its rapid growth cycle.
• Pick an Airy Substrate: A well-draining soil mix or coco coir is perfect. For a hassle-free start that promotes explosive root development, consider a root stimulator like Plagron Power Roots.
• Lighting is Key: Indoors, provide 18-20 hours of light daily. Outdoors, plant after the last frost when temperatures consistently stay above 10°C (50°F).

During the Grow: Vigorous and Forgiving

Watching Big Bang Auto grow is a joy. It's a sturdy, bushy plant that stays compact, typically reaching 60–100 cm (23.6–39.4 in) tall, making it perfect for Sea of Green (SOG) setups or discreet gardens.

Its genetics make it highly resilient to common grower mistakes. It handles slight nutrient fluctuations well and has good resistance to moulds and pests. You'll see it transition to flowering automatically, filling out with dense, pointy buds that become absolutely caked in sparkling trichomes.

After Harvest: The Reward

In just 6-7 weeks of flowering, you'll be rewarded with a substantial haul. Indoor yields can reach up to 900 g/m² (2.96 oz/ft²), while outdoor plants can produce 45–80 g (1.59–2.82 oz) each. The buds are dense, sticky, and emanate a classic skunky aroma with sweet, fruity undertones. A proper dry and cure will lock in those complex flavours of earth, spice, and sweet apple.

Big Bang Autoflowering is incredibly fast. You can expect to harvest dense, potent buds in approximately 10 to 11 weeks from the day you germinate the seed.

How much can I yield per plant?

Personal Experience of Pevgrow’s CEO (Alan)

I've run Big Bang Auto several times, and it's my go-to recommendation for anyone wanting a 'set it and forget it' grow with professional results. Before popping the seed, I make sure my environment is dialled in—stable temps around 23-26°C and a good quality, light soil mix. I plant directly into a 20 L (5.3 gal) final pot to avoid any transplant shock.

During the grow, I'm always impressed by its vigour. It stays short and bushy, perfect for a crowded tent. I give it a light LST (Low Stress Training) about 3 weeks in to open up the canopy, but I avoid any topping or fimming—autos don't have time to recover from high-stress techniques. I keep the nutrients simple; a light base feed during veg and then a good PK booster like Bloombastic during weeks 3-5 of flowering really makes the buds stack and swell.

After harvest, the buds are rock-hard and dripping with resin. The smell is unmistakably old-school skunk with a sweet twist. The effect is exactly what I want after a long day: a heavy, relaxing body stone that doesn't couch-lock me completely, but definitely encourages a serious chill session. It's a consistent performer that never lets me down.
