What are Autoflowers?

Autoflowers are a unique type of cannabis plant that flower based on age rather than light cycle. Unlike traditional photoperiod strains that rely on specific hours of light and darkness to transition from vegetative growth to flowering, autoflowers enter the flowering phase automatically—usually within 2 to 4 weeks after sprouting.

This trait comes from their genetics, which include *Cannabis ruderalis*, a hardy subspecies native to regions with short summers and extreme conditions. The result? A fast, resilient plant that’s ideal for growers looking for speed, simplicity, or stealth.

Why Choose Autoflowers?

For many growers, the appeal of autoflowers lies in their convenience. Since they don’t depend on light cycles, you can grow them under 18–24 hours of light from start to finish. This makes them perfect for small indoor spaces, balconies, or outdoor grows where controlling light isn’t practical.

Autoflowers are also generally more compact and less demanding than photoperiod plants. They’re a great choice for beginners, short-season climates, or anyone looking to harvest multiple cycles per year.

Autoflower vs. Photoperiod: What’s the Difference?

The main difference is control. Photoperiod plants give you more say over when they flower, and often produce larger yields if grown properly. Autoflowers, on the other hand, are on a set schedule—once the clock starts, there’s no turning back. But that also means no need to flip lights or worry about accidental light leaks.

Autoflowers tend to have shorter lifespans (8–12 weeks from seed to harvest), smaller size, and slightly lower yields—but breeders have come a long way in closing the gap. Today’s autos can rival traditional strains in potency, flavor, and bag appeal.

Tips for Growing Autoflowers

• Start strong: Since autos move fast, avoid transplant shock. Start in the final pot or use biodegradable starter pots.
• Keep feeding gentle: Autos don’t like heavy nutrients early on. Use balanced, organic soil with light top-dressing.
• Mind the timing: There’s no time for recovery. Stressing an auto early—overwatering, topping, transplanting—can reduce final yield.
• Choose genetics wisely: Some autos are bred for size, others for speed. Match your strain to your goals.

Whether you're new to growing or a seasoned cultivator looking for efficiency, autoflowers offer a streamlined path to harvest. They’re reliable, discreet, and surprisingly powerful for their size and speed.

In short, autoflowers give you more harvests with less hassle—and for many growers, that’s the future.
