How to Grow Autoflower Seeds Outside: A Comprehensive Guide

Autoflowering cannabis seeds have revolutionized the world of cannabis cultivation. These hardy, fast-growing plants are perfect for outdoor growers, especially those in regions with shorter summers. But how do you get the most out of your autoflower seeds? Let’s dive in.

Understanding Autoflowering Cannabis

Before we delve into the specifics of growing autoflower seeds outside, it’s crucial to understand what makes these plants unique. Unlike traditional cannabis plants, autoflowers don’t rely on light cycles to trigger flowering. Instead, they automatically transition from the vegetative stage to the flowering stage after a certain period, typically 2-4 weeks. This trait makes them ideal for outdoor cultivation, as they can be harvested multiple times in a single growing season.

Choosing the Right Autoflower Seeds

Not all autoflower seeds are created equal. Some strains are better suited to outdoor cultivation than others. When choosing your seeds, consider factors like resistance to pests and diseases, yield potential, and the plant’s size. Smaller plants are generally easier to manage and less conspicuous, making them a good choice for stealth grows.

Preparing Your Grow Site

Autoflowers are adaptable and can thrive in a variety of conditions, but they do best in well-draining soil with a pH between 6.0 and 7.0. They also need plenty of sunlight – at least 18 hours a day is ideal. Choose a site that gets ample sun and is protected from strong winds and heavy rain.

Planting Your Autoflower Seeds

Autoflower seeds can be planted directly in the ground or in pots. If you’re planting in the ground, dig a hole about twice the size of the seed and place it in the hole, pointy end down. Cover the seed with soil and water it gently. If you’re planting in pots, use a pot that’s at least 3 gallons in size to give the roots plenty of room to grow.

Caring for Your Autoflower Plants

Autoflowers are relatively low-maintenance, but they still need some care to thrive. Water them regularly, but be careful not to overwater, as this can lead to root rot. Feed them with a balanced nutrient solution, but avoid over-fertilizing, as autoflowers are sensitive to nutrient burn. Regularly check your plants for signs of pests or diseases and take action at the first sign of trouble.

Harvesting Your Autoflower Plants

Autoflowers typically take 8-10 weeks from seed to harvest. When the majority of the trichomes on your plants have turned milky white and about 70% of the pistils have darkened and curled in, it’s time to harvest. Cut the plants at the base, trim off the fan leaves, and hang them upside down in a cool, dark place to dry.


Growing autoflower seeds outside can be a rewarding experience, yielding a bountiful harvest in a short amount of time. By understanding the unique needs of these plants and providing them with the right conditions, you can enjoy success with your outdoor autoflower grow. Happy growing!
