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.

1. Blueberry Auto

One of the best strains for strong terpene profile lovers and an Indica-dominant powerhouse as well. 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.

A legendary strain now in auto version. Blueberry Auto offers that stereotypical Indica high combined with a nice head high that’ll leave you like you’re lying on a bed of clouds.


The strong effects and compact structure make it the perfect plant for those with limited space who are looking for a high-THC plant with a strong Indica effect that keeps the pain away.

2. Gorilla Glue Auto

Fast Buds fans have turned our Gorilla Glue Auto into an international sensation. This top-selling strain grows dense, resinous buds coated in white, sticky, and surprisingly strong resin, hence the name.

I grew my Girl Scout plant outdoors and the weather was mostly cloudy in flower with frequent rains. There were no issues with mold though.

There's nothing quite like Mimosa Cake Auto. The terpene profile you'll feel from this strain is like no other. Its signature fruity terpene profile produces a relaxing, mellow high like you've never felt before.
