Best Autoflowering Marijuana Seeds

The cultivation of marijuana seeds can come in all different forms and methods. Today, we are offered a choice of growing either regular, feminized, or autoflowering seeds. Autoflowering seeds are the newest type of cannabis seeds to hit the markets and have been extensively used by growers from all around the world! With their unique traits and ability to generate weed buds quickly and easily, autoflowering seeds are a great choice for both indoor and outdoor gardens!

Where Do Autoflowering Seeds Come From?

Autoflowering seeds come from the distinct Cannabis Ruderalis subspecies of marijuana plants. They are indigenous to places that display harsh weathers and extreme growing conditions. Through these, the cannabis ruderalis was able to adapt to its environment and develop the autoflowering ability. This autoflowering ability allows the cannabis plants to grow at their own pace with little to no consideration of the amount of sunlight it receives (in contrast to photoperiod seeds). Thus, they flower automatically regardless of the lighting hours that they are exposed to.

While the cannabis ruderalis is a separate type of weed altogether, it is usually unfit for consumption by itself. This is due to the low levels of THC that it comes with. As such, smoking pure ruderalis by itself will give you a buzz but nothing compared to what indica and sativa users are used to.

As such, the genetics of ruderalis are often crossed with any type of hybrid in order to give it the qualities of a high-inducing strain. These hybrids crossed with ruderalis are generally termed as autoflowering seeds

Here are the best autoflowering marijuana seeds that you can get your hands on! These surely won’t disappoint you!
