Outdoor growers love Fast Buds' autoflowers. Maybe it's the nine to ten-week flowering time. Maybe it's the massive yields. Maybe it's the Gorilla Glue. Whatever the reason, we hear from growers in equatorial Africa to Sweeden every day who love their results with Fast Buds. While all our strains grow well outdoors thanks to their autoflower heritage, some strains grow larger or perform slightly differently in outdoor environments. For those of you lucky enough to be able to cultivate outdoors, we'll run down the top five best strains for growing under the sun. If you missed it, we ran recently ran down our Top 5 Best Indoor Autoflower Strains.

1. Gorilla Glue Auto

A true cultural sensation, Fast Buds' autoflowering take on the legendary Gorilla Glue #4 remains our most popular strain, even a year after its release. At cannabis fairs, growers descend upon the Fast Buds' booth trying to buy out our supply before anyone else!

Gorilla Glue Auto.

This strain can grow to over a meter in height, a true giant by autoflower standards, and when it hits flowering it packs on grams and grams of dense, rock-hard buds. Fast Buds' autoflower genetics mean this strain is a bit hardier than its photoperiod ancestor, making it perfect for growing outdoors.

2. Amnesia Zkittlez Auto

"It's a huge one!" That's what growers keep telling us about Amnesia Zkittlez Auto at shows across the continent. To hear them tell it, this tall and durable strain is quickly becoming a household name amongst stoners across the UK, replacing cheese and the vaguely defined "skunk" as the most sought-after strain.

Amnesia Zkittlez Auto is perfect for outdoor growing in colder climates like the UK, and northern Europe. It's hardy, packs on the buds, and hits THC levels exceeding 27%. As a total package, Amnesia Zkittlez Auto can't be beaten.

3. Bruce Banner Auto

Bruce Banner Auto is a great choice for outdoor growers as it’s an XXL autoflower that produces up to 200g/plant in 10/11 weeks.

This Sativa-dominant hybrid explodes with high-THC buds under the summer sun, and was created with outdoor growers in mind. It's a favorite for outdoor Fast Buds fans in every climate. If you're looking for a low-maintenance yet strong Sativa, don't miss Bruce Banner Auto.

4. Six Shooter Auto

If you want a high yield, look no further than Six-Shooter. This Sativa giant is our heaviest yielder. It's also our second largest strain, reaching nearly 1.4 meters in height.

Like Bruce Banner Auto, Six Shooter Auto produces giant colas of energetic flowers flowing with resin. This cross between our Sativa heavy hitters Mexican Airlines and Crystal Meth flowers in nine to ten weeks when grown outdoors, meaning that, even in a cold climate, a dedicated grower could squeeze in several crops over the course of a summer.

5. Gorilla Zkittlez Auto

The perfect outdoor autoflower. Gorilla Zkittlez Auto is a marvelous Fast Buds strain, that takes the always-popular Zkittlez and turns it into a giant outdoor autoflower powerhouse.

Gorilla Zkittlez Auto.

Our Gorilla Zkittlez Auto has just one first place in the latest edition of Dabadoo in Brazil in the ‘Best Solvent-Based concentrate’ category, so you should definitely give it a shot. Easily our largest strain, Gorilla Zkittlez Auto hits the heights of Six Shooter while producing in bulk and outstanding bud quality. We've seen more than a few Gorilla Zkittlez overgrow their tents. The growers weren't prepared because autoflowers don't get this big. Well, they didn't until Gorilla Zkittlez Auto came along.

Like our other giant outdoor strains, this variety is an Indica-dominant hybrid. Unlike our other Indicas, the stimulating effects are minimal, making this a perfect anytime strain. It won't leave you wired or locked on the couch.

6. In conclusion

While these strains are a great starting point, don't limit yourself to them. Fast Buds' other Sativas like Orange Sherbet Auto and Mimosa Cake Auto grow well outside as quite well. If you're a fan of hybrids, Gorilla Cookies Auto performs well in any environment. And if you're looking for a nighttime Indica, our newest strain, Banana Purple Punch Auto might have the magic you're looking for.
