Autoflowering cannabis seeds are easy to grow, a joy to smoke, and offer great yields. They are equally suited for budding beginners and experienced cultivators seeking an efficient harvest. Check out the main benefits of autos below, and then explore five of the best autoflowering weed seeds to grow indoors.
Benefits of Autoflowering Cannabis
Autoflowering cannabis varieties come with a host of benefits that make them super easy to grow:
- Resilient against pests and disease
- Go from seed to harvest in 8–10 weeks on average
- Small, stealthy, and easy to manage
- Don’t require a change in light cycle to flower
- Low demand for nutrients
Why Grow Autos Indoors?
Growing autos indoors allows cultivators to control all aspects of the environment. By managing watering, nutrients, and lighting, growers can strike the perfect balance that healthy cannabis plants need.
Outdoor plants offer great results, but they are exposed to the whims of nature—e.g. floods, strong winds, droughts, and a higher chance of pests and disease.
Growing indoors is also a better option in areas where cannabis is illegal. The use of a growing tent and carbon filter can keep plants out of sight and stinky terpenes out of the air, reducing the chance of getting busted.
Light Schedule for Indoor Autos
Unlike photoperiod strains, autoflowering strains don’t require a change in the light cycle to start flowering. These plants originated in darker and colder regions, and therefore don’t rely on external cues to progress through their life cycle. Instead, they do this all by themselves after a matter of weeks.
As such, you can maintain a light cycle of 18 hours on and 6 hours off throughout the entire growing cycle—nice and easy.
Quick Tips for Growing Autos Indoors
Autos are inherently easy to grow. However, cultivators can make matters even more simple by using these key tips:
- Transplant once: After germination, place your seedling directly into its final pot to avoid transplant stress further down the line.
- Go easy on watering: Only water when the top inch of soil becomes completely dry. Overwatering ends many grows before they even really get started.
- Invest in good lights: Make lights your most expensive purchase. Poor-quality lights will stunt growth and reduce yields.
Can You Train Autos?
Yes! Training refers to manipulating the shape of your plant in a particular way, usually to increase yields or limit growth. While you can train autos, we suggest going with a low-stress method that won’t inflict too much damage.
Autos grow so fast that highly stressful training techniques can seriously reduce yields. By the time they recover, they’ll likely already have entered the flowering stage.
Instead, try out some LST to increase yields without hampering your plants’ development.
