Understanding Autoflowers: What Makes Them Unique?

What Are Autoflowering Plants?

Autoflowering cannabis strains are hybrids of the Cannabis sativa and Cannabis ruderalis species. Unlike photoperiod strains that rely on changes in light cycles to trigger flowering, autoflowers begin to flower automatically after a specific period, usually 2-4 weeks from germination. This unique trait makes them a versatile choice for outdoor growing.

Advantages of Autoflowers

• Short Growing Cycle: Autoflowers can complete their life cycle in as little as 8-10 weeks, allowing for multiple harvests in a single growing season.
• Resilience: These plants are typically more resistant to pests, diseases, and harsh weather conditions, making them ideal for outdoor environments.
• Compact Size: Autoflowers are generally smaller and more manageable, perfect for discreet outdoor grows or limited space.

Factors Influencing the Ideal Time to Grow Autoflowers Outdoors

Climate Considerations

Climate plays a pivotal role in determining the best time to grow autoflowers outdoors. Different regions offer varied growing conditions that can significantly impact the growth and yield of your plants.

Temperature

• Optimal Range: Autoflowers thrive in temperatures between 70°F (21°C) and 85°F (29°C). Extreme temperatures can stress the plants, affecting growth and yield.
• Avoid Frost: In colder climates, it’s crucial to plant after the last frost of spring and harvest before the first frost of fall to prevent damage.

Humidity

• Ideal Humidity Levels: During the vegetative stage, autoflowers prefer humidity levels of 40-60%. During the flowering stage, 30-40% is ideal to prevent mold and mildew.
• Monitoring: Use hygrometers to monitor and adjust humidity levels, especially in regions with high moisture.

Light Exposure

Autoflowers require ample light to produce high-quality buds. Although they don’t depend on light cycles, more light generally equates to better growth and yields.

Daylight Hours

• Spring and Summer: The longer daylight hours of spring and summer provide the necessary energy for growth. Aim for at least 12-18 hours of sunlight per day.
• Light Intensity: Ensure your plants receive direct sunlight to maximize photosynthesis and nutrient absorption.

Seasonal Timing

Choosing the right season to plant autoflowers outdoors is crucial for maximizing yield and potency.

Spring Planting

• Early Start: Planting in early spring allows for multiple harvests. Ensure temperatures are stable and frost-free.
• Extended Light: Longer days provide the ideal conditions for rapid growth and flowering.

Summer Planting

• Optimal Growth: Summer offers peak growing conditions with maximum sunlight and warmth. This is the best time for most regions.
• Monitor Heat: Be cautious of extreme heat and provide shade or watering to prevent stress.

Fall Harvest

• Late Season Planting: In some regions, a late summer planting can yield a fall harvest. Ensure your plants will mature before the first frost.
• Shorter Days: The reduced light can slow growth, so choose fast-maturing autoflower strains.

To get the best results with autoflowers, we recommend starting in the first 2 weeks of June. Then they grow fine due to the warmer temperatures and they also usually get more sun hours than if you start in April. They will then flower at the beginning of July and get the best temperature and sunlight hours for an exuberant bloom. The buds will therefore grow bigger and harder and finish flowering perfectly at the end of August. The drop in temperature at the beginning of September will also stimulate THC production. So there is no better time for growing autoflowering cannabis outdoors.

Geographic Location

Your geographic location significantly affects the ideal planting time for autoflowers.

Northern Hemisphere

• Best Time: Plant autoflowers from late April to early July to capitalize on the long days and warm temperatures.
• Challenges: Shorter growing season and potential for early frost.

Southern Hemisphere

• Best Time: Plant from late October to early January. The longer days and warmer temperatures of summer are ideal.
• Challenges: Heat and water management in hot regions.

Local Weather Patterns

Keep an eye on local weather patterns, as sudden changes can affect your plants. Use weather apps to monitor conditions and plan accordingly.

Choosing the Right Autoflower Strains for Outdoor Growing

Not all autoflower strains are created equal. Selecting the right strains can make a significant difference in your outdoor growing success.

Climate-Adapted Strains

Choose strains that are suited to your local climate to ensure resilience and optimal growth.

Cool Climates

• Strains: Consider hardy Autoflower strains like Northern Lights, Mimosa or OG Kush known for their resilience in cooler temperatures.
• Characteristics: These strains typically have shorter flowering times and better resistance to cold.

Warm Climates

• Strains: Opt for autoflowering strains like Amnesia Haze, Amnesia Cookies, or Gorilla Glue, which thrive in warmer temperatures.
• Characteristics: These plants can handle higher temperatures and longer growing seasons.

Ideal pot size

All Autoflowering cannabis strains grow short on small pots. It is therefore very important to put them on their final pot as soon as possible. If you want to grow small compact autoflowering plants use a pot between 3 and 10 liters. If you want larger plants use 10 to 20 liter pots. The advantage of growing on pots is that you can move them around. This way you can protect them from rain and/or give them a few extra hours of sun by moving them with the sun. After all, every hour of extra sun gives a better end result. The disadvantage of growing in pots is that you have to water them more often and on smaller pots you also have to give them extra nutrition. If you place the plants in the open ground without a pot, you basically have nothing to worry about. They will grow to their maximum size and if the roots can grow freely you don’t have to give them extra water and/or nutrition. Let nature do the work and enjoy a carefree cultivation.

Steps to Successfully Grow Autoflowers Outdoors

Preparation and Planning

Proper planning sets the foundation for a successful outdoor autoflower grow.

Site Selection

• Sunlight: Choose a location that receives maximum sunlight throughout the day.
• Soil: Ensure well-draining, nutrient-rich soil. Amend with compost or organic matter if needed.
• Protection: Consider windbreaks or barriers to protect plants from strong winds and pests.
