Is anybody else ever amazed at the technology, innovation, and resilience it takes to grow good marijuana indoors? Prohibition is the mother of invention it seems. Whether you're growing indoors in order to keep things discreet, or you just don't have a garden to plant seeds, we're running down the five best autoflower strains to grow indoors. While these strains grow well indoors, all Fast Buds strains perform well outdoors as well. These varieties just have a few traits that an indoor grower might value, like discretion, grow time, or size.

One of the best strains for growers who enjoy strong tropical terpene profile on a super well-balanced autoflowering powerhouse. When you hear old hippies complaining that, "weed these days isn’t like it used to be" they're definitely not talking about this delicious autoflower.

Honorable Mention

For aficionados of Sativa autoflowering strains, we really recommend our Sour Jealousy Auto. This robust Sativa-dominant cultivar can reach to heights of up to 150cm, boasting a yield potential of up to 600 grams per square meter.
