Top 8 Best Sativa Autoflower Strains to Grow - 2021 UPDATE

News

Sativa is generally perceived as more cerebral than Indica-dominant strains, and it’s noted for its tall height and narrow structure. The result is that Sativa can be somewhat more difficult to grow, thanks in part to its long flowering period.

What better way to enjoy this ever-popular plant than with an autoflowering variety? This new breed makes it far easier to achieve great results and to control good yields with less experience. Are you searching for the perfect Sativa autoflower strain? Here we break down the top options to go for.

What is a Sativa Autoflower?

Typical Sativa cannabis plants are photo-period dependent. That means that they rely on a specific ratio of light and dark to flower and produce their buds. This requires great skill to cultivate, with constant care and attention during its life cycle. In good, solid hands, the results are superb. The issue is that most of us don’t have this kind of time to dedicate to growing. The solution? Autoflowering Sativa seeds.

Why you should choose a Sativa autoflower

Autoflower Sativa strains mature fast and produce generous yields. They are created by blending Sativa strains with Ruderalis, one of the hardiest cannabis subspecies. Perfect for beginners or those with busy lives, you don’t have to worry about specific light schedules.

They autoflower from the vegetative stage based on their age, not light conditions. The plant still need good light and heat for growth, but the flowering time doesn’t depend on it. Furthermore, they also tend to have high fungal resistance, making them more robust in general. Sativa in and of itself tends to have a higher humidity tolerance, so this autoflowering addition pushes it over the edge as a beginners true favorite.

The benefits are clear: Sativa autoflower strains grow quick, flower quick, can deal better with less optimal environments and provide multiple harvests outdoors per season. For those new to growing, Sativa autoflowering strains are a boon. So which one should you choose?
