What Is Autoflowering Cannabis?
Autoflowering cannabis is a revolutionary breed of cannabis plant that flowers based on age rather than light cycles, making it simpler and faster to grow. The story of autos begins with the hardy Cannabis Ruderalis, a wild subspecies discovered in the harsh climates of Eastern Europe. Thanks to its natural habitat, Ruderalis developed the kind of survival instincts needed to make it through tough conditions, making it a friend to cultivators ever since. Crossbreeding this rugged survivor with potent photoperiod strains birthed the autoflowering cannabis we know and love today, the kind that will withstand the elements and produce the goods even when tested by nature.
Seedsman was the first seedbank to introduce autoflowering cannabis seeds for commercial sale, debuting with the now-legendary Lowryder strain, courtesy of The Joint Doctor – so if you’re looking for autoflowering cannabis seeds, you’ve come to the best place. Since those early days, autos have evolved dramatically, boasting ever-more impressive yields, rich terpene profiles, and powerful potency – all with a fraction of the hassle.
Why Grow Autoflowering Cannabis?
There’s plenty of reasons to fall in love with autoflowers. For one, they’re fast – many strains grow from seed to harvest in as little as 8-10 weeks. They’re compact, typically growing to between two and four feet tall, making them ideal for stealth or small-space grows. They’re resillient, thriving even in suboptimal conditions. And they’re easy, making them perfect for beginners and a joy for pros who want quick, reliable crops. Plus, with no need to worry about light cycles, you can grow them almost anywhere, and anytime – indoors, outdoors, or even in a small closet with nothing more than a grow light and a dream.
