Growing Autoflower Cannabis Indoors: Best Practices
Growing autoflower cannabis indoors is a game-changer for beginners and seasoned growers alike. These strains, known for their fast growth and independence from light cycles, thrive in controlled environments. To get the most out of your indoor autoflower garden, follow these best practices for a bountiful harvest.
Start with Quality Seeds
The foundation of success lies in choosing high-quality autoflower seeds like Sour 60, Gorilla Glue, or White Widow. Buy from reputable seed banks to ensure genetics that deliver fast growth and resilience. Healthy seeds mean healthier plants, so don’t skimp here.
Optimize Your Lighting
Autoflowers don’t need light schedule changes, making them ideal for indoors. Use full-spectrum LED lights (100-200W for small setups) and run them 18-20 hours daily from seed to harvest. Position lights 12-18 inches above plants, adjusting as they grow, to maximize photosynthesis without burning delicate leaves.
Choose the Right Medium and Pot
Pre-mixed, well-draining soil works best for autoflowers, as they’re sensitive to overwatering. Avoid heavy soils that retain too much moisture. Use 3-5 gallon fabric pots to promote air circulation and root health—autoflowers don’t like being transplanted, so plant them in their final container from the start.
Water and Feed Lightly
Overwatering is the top mistake with autoflowers. Water only when the top inch of soil feels dry, and use half-strength nutrients designed for cannabis. Start feeding two weeks after germination, as autoflowers have a short life cycle (8-12 weeks) and don’t need heavy doses.
Control the Environment
Keep temperatures between 70-80°F and humidity at 40-50% during vegetative growth, dropping to 30-40% in flowering. Good airflow from a small fan prevents mold and strengthens stems.

Hello from Boston. My current arrangement is for house plants, using one round hooded fixture with an LED and a reflecting imterior and an 11-watt bulb; the other light source is a multi-armed grow light with red, white, and blue bulbs. The plants would stay indoors, getting some direct sunlight from a west-facing window that has sun starting around March and stopping in the autumn. The idea is to start three plants for personal use in 12-inch containers.
The current plants are a very old and treasured Chistmas cactus, a smaller cactus that is being propagated as a gift, and three plugs of New England asters for planting later in the season. All are on heated mats and seem to be doing well; all the plants can be easily relocated. With some rearranging, there would be room for three 12-inch pots. Would this set-up be adequate for my plans?
After some research, I have decided that Sour LowRyder 2 Autoflower might be the best choice. for seeds If this might be a bad decision, please let me know what might work better.
