Fast Autoflowering Seed Strains
Fastest autoflowering cannabis seed strains
With auto-flowering strains can you grow almost anywhere and harvest between 55 to 75 days after germinating the seeds.
What’s fast autoflowering cannabis and why is so popular?
Auto-flowering cannabis strains are different from most types of marijuana in that they begin to flower (produce buds) not long after germination and continue to do so throughout their life cycle.
(The original auto-flowering cannabis strains are called Ruderalis but they didn’t contain any psychoactive substances like THC so they were bred with potent Sativas and Indicas to make a whole new strain of cannabis – auto-flowering strains that will get you high!)
Most cannabis strains need equal spells of dark and light every 24 hours before they will begin to start budding. If the plants are exposed to more than 12 hours of light every 24 hours then they will continue to grow but not flower or form buds. Bummer!
Not so with auto-flowering cannabis. These suckers will start to flower a few weeks after germination and continue to flower for their short but potent life cycle.
So if you’re growing in a room that can’t be kept completely dark for at least 12 hours a day you’ll want to get auto-flowering seeds. Perfect for my buddy who grows under lights in his rec room (also for folk growing outside in urban areas with excessive light pollution).
Multiple harvest in one growing season
Some auto-flowering cannabis strains are also fast to grow which makes a shorter wait for harvest time. This means you can be harvesting your crop in as little as two months after germinating the seeds.
Outdoors, this means you can plant and harvest two or three crops in a summer growing season.
Indoors it means you can have at least 5 crops from seed to harvest each year.
Fast does not mean big
Now don’t expect huge 450+ gram harvests for each plant from these small but mighty strains. 30 to 120 grams harvested from each autofem seed is more likely. (For biggest harvests, see auto-flowering strains Think Different and Green-o-matic below). If you want to harvest large quantities of high-grade marijuana every two months you’ll have to grow a dozen or more of these autoflowering strains at a time!
Below is a list of the best autoflowering cannabis strains available to buy on-line in feminised seed form. Each strain below has been selected for the following qualities: speed, potency, effect, taste and popularity.
