Autoflowers can be started in early spring and will flower during the longest days of summer, taking advantage of high quality light to get bigger yields. Or, if you get a late start in the growing season, you can start autoflowers in May or June and harvest in the fall.
In some cases, even if a seed isn’t completely mature, there’s still a chance it could be viable. But often these are extremely weak, take long to develop, and express other unfavorable characteristics. Growers usually discard weak plants to free up space.
Tips for growing autoflower marijuana seeds
Take four sheets of paper towels and soak them with distilled water. The towels should be soaked but shouldn’t have excess water running off.
Through cloning, you can create a new harvest with exact replicas of your favorite plant. Because genetics are identical, a clone will give you a plant with the same characteristics as the mother, such as flavor, cannabinoid profile, yield, grow time, etc. So if you come across a specific strain or phenotype you really like, you might want to clone it to reproduce more buds that have the same effects and characteristics.
Is the seed viable?
Females will have a round structure with long hairs—these hairs will develop into pistils, which will catch pollen in the air.
The really exciting part is the auto-flowering world is evolving quickly. More and more breeders continue making new auto strains. We’re starting to see better and better yields, more nuanced potency, and a lot more variation when it comes to harvest times, plant size and growth rates.

The term “12-12” stands for 12 hours of light and 12 hours of dark each day, and it “tells” photoperiod plants to enter the flowering stage and make buds. During their daily dark period, photoperiod plants need to receive complete darkness without interruption. This light schedule initiates flowering, and must be maintained throughout the entire flowering stage until harvest.
This was the final height of a “Lowryder” auto plant grown in a very sunny window. Lowryders tend to stay the smallest of almost all auto-flowering strains. This plant ended up having very small yields because it was grown in a window. It’s difficult to find a window that gets 5+ hours of direct sunlight each day, and generally it’s recommended that most growers avoid growing in a window if they want to get decent yields.
Note: Autos by Nirvana are marked with a plus + sign.
When considering yields, it’s important to remember that one of the advantages of growing auto-flowering cannabis strains is most growers can produce several harvests a year (since the lifespan of each auto plant is very short).
