The Best Autoflowering Indica Strains
Autoflower seeds are great for beginners and experienced growers because they’re easy to care for and are resilient to pests and diseases. In this article, you’ll learn the best indica autoflower strains to grow indoors and outdoors.
The two types of Cannabis plants are indica and sativa, both with their own characteristics and effects. Indica seeds typically produce round, broad leaves with a darker coloring, compared to sativa, which looks narrow and dainty with a lighter color.
Visual differences aren’t the only aspect that differentiates the two types of Cannabis plants. Sativa often contains high levels of THC and is known for the cerebral high that it provides Cannabis consumers. On the other hand, indica often gives more of a sedative and relaxed effect.
