How To Choose The Right Lighting For Your Marijuana Grow Room

What Are Autoflowering Seeds?

Autoflowering cannabis seeds result from a crossbreed between Ruderalis and indica or Sativa strains. Cannabis Ruderalis was once considered a wild weed, but it has been brought indoors in recent years to create new hybrid autoflowering cannabis. The Ruderalis genes allow the plant to flower automatically, regardless of the number of hours of darkness it receives.

This makes autoflowering cannabis strains ideal for growing in outdoor regions with shorter summer days due to their quick flowering cycles.

Autoflower cannabis seeds are easy to grow, especially when combined with the easiest marijuana strains to cultivate.

Below we cover some of the best and easiest strains to grow using autoflower seeds for both outdoor and indoor growers. But, before we get into the best autoflowering strains, there are some things to think about prior to buying your auto seeds.

The easiest cannabis strains to grow are autoflower strains. Although the outcome for these autoflower seeds results in a smaller plant than traditional cannabis seeds when they reach maturity, the resulting cannabis plants will start to flower when they are ready.

This takes much of the guesswork out of gardening when it comes time to switch your LED grow lights to bloom.

The cannabis seeds, simply switch from veg to flowering on their own. Pretty cool results, and you can see why people love autoflowering strains so much!

Autoflowering cannabis seeds are a type of seed that will cause the plant to flower on its own after 2–4 weeks of growth.

Just as they would if growing feminized photoperiod cannabis.

Autoflowers mature much faster than traditional plants– some can be harvested 8 weeks after sprouting. Autoflowers are not only great for indoor growing, but they are also compact.

Autoflowers are not only convenient but also ideal for beginners in cannabis cultivation.

Autoflowering cannabis has unique growing traits that can be taken advantage of by more experienced growers as well.

Do autoflowering cannabis seeds have lower THC levels?

Some growers shy away from autoflowers because they believe these plants have lower THC levels.

They have come a long way in a few short years.

Autoflowering Strain FAQs

Will it hurt an autoflower to have 24 hours of light?

Autoflowers can grow under a 24-hour light schedule from seed to harvest; a dark cycle isn’t necessary. Some people feel that autoflower plants do best with a 20/4 light cycle, while others believe an 18/6 light cycle is more effective.

From personal experience with autoflowers I prefer a 20/4 light cycle myself but never noticed a huge difference. Autoflower seeds don’t seem to care.

What’s the best way to grow autoflowers?

Autoflower plants can be grown in a variety of ways, including hydroponically, in soil, or in coco coir. The best way to grow autoflowers is the way that works best for you. There is no one “right” way to grow autoflowers.

I’ve personally grown auto flowering seeds in soil, coco coir, and hydroponically, and all three methods worked well.

Autoflowering seeds vs photoperiod seeds

Autoflowering cultivars grow quickly and are simple to cultivate, while photoperiod strains take longer to mature but provide larger yields. It really comes down to personal preference which type of cannabis you want to grow.

If you’re looking for a fast, easy-to-grow plant, then autoflowers are a great choice. If you’re looking for bigger yields and more THC, then photoperiod strains are your ticket to grow.
