Best Autoflower Strains

Most weed plants require a certain amount of sunshine to graduate from the vegetative to the flowering phase. This process happens best during autumn because that’s when there starts to be more darkness. This nighttime darkness tells plants it’s about to start getting cold outside. But with the best autoflower strains, the ratio of sun to darkness doesn’t matter.

Autoflowering cannabis strains start the flowering phase naturally after a certain amount of time. This is perfect for growers looking for strains that can transition from germination to harvest quickly. These auto strains can be planted, cultivated, and harvested indoors, no matter what time of the year it is.

White Widow Autoflower

White Widow is an indica-dominant strain with Dutch origins. Brazilian Sativa and South Indian Indica are the parent strains of this Amsterdam coffee shop favorite. Today, it’s the proud parent of such strains as Blue Widow, White Russian, and White Rhino.

Autoflowering strains of this classic experience deliver potent results. When grown in optimal indoor conditions, White Widow Autoflower can yield about 4 ounces of usable cannabis per 3 square feet within 8-9 weeks. The plants grow to heights between 20-24 inches and produce buds that deliver a powerful euphoria with up to 19% THC.

The Indica-dominant seeds consistently grow high yields of 4-6 ounces of smokable marijuana per 3-square-feet within about eight weeks. Indoor growers must ensure that the plants receive an ample amount of light for the plants to reach their full potential.
