The Best Autoflowering Indica Strains

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.

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. 

Granddaddy Purple

With a rich heritage derived from Hindu Kush, Granddaddy Purple is a 100% indica strain with high levels of THC up to 23%. GDP is great for new growers and Cannabis cultivators who want to take advantage of smaller spaces, as the plants are compact and small.
