Top Auto Indoor Cannabis Strains 24

Autoflower 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.

Top 5 Autoflower Weed Seeds for Indoor Growing

Behold; five excellent autos for cultivating indoors. Whether you have a whole room at your disposal or are working within a modified closet, you can achieve excellent results. Each cultivar offers something special to the grower, but all perform exceptionally well.

Brand New & Potent: Goat’lato Auto

A collaborative creation from Royal Queen Seeds and Mike Tyson’s Tyson 2.0 brand, Goat’lato Auto offers colorful buds, plenty of THC, and a compact stature that makes it perfect for growing indoors.

Sow these weed seeds directly into 11 l pots filled with a high-quality potting mix, and maintain a temperature of 25–28°C for swift germination. Your plants will stand at a height of 9 cm two weeks after sprouting, exhibiting several sets of small true leaves. Aim for a relative humidity of 50% and keep your lights on for at least 18 hours per day; your plants will reach 19 cm by the end of week three. During week four, your Goat’lato Auto specimens will start producing pre-flowers and transition into bloom. Apply some light defoliation to open up the canopy, increasing light penetration and aeration.

Aim to reduce humidity levels to 30–40% throughout bloom to decrease the risk of mold. Anticipate your plants stretching up to 120 cm depending on any training techniques used. Throughout the flowering phase, those pre-flowers will quickly mature into large, dense buds with eye-catching purple hues. Prepare to harvest up to 450 g/m² indoors after a brief growing cycle of just 10–11 weeks. After drying and curing your buds, you’ll experience a soothing and euphoric effect alongside flavors of cookies, earth, and fruit.
