Autoflower Light Cycle/Schedule

Although cultivating autoflowering cannabis plants may seem straightforward, there’s plenty to consider if you want to maximize your yield. One of the most crucial considerations is finding the best light schedule for autoflowers. Our guide explores the perfect autoflower light cycle to help you get the most out of your cannabis plants. 

Understanding Autoflowers

Autoflowers, short for autoflowering cannabis plants, have revolutionized the world of cannabis cultivation. Unlike their photoperiod counterparts, which require specific light cycles to transition from the vegetative to the flowering stage, autoflowers switch to flowering based on their age. These strains also boast several other benefits that make them ideal for growing weed both indoors and outdoors. 

The Ideal Autoflower Light Cycle

What is the best light cycle for autoflowers, then? Unlike regular cannabis strains, autoflowers are not dependent on light cycles to trigger the flowering stage. However, it’s still vital to provide them with adequate light to optimize growth and yield.

While many growers have their own preferences, a common consensus is that autoflowers do best with 18 to 24 hours of light every day throughout their life cycle. A 20/4 cycle (20 hours of light, 4 hours of darkness) is often considered a sweet spot. This offers a good balance between optimal growth and energy consumption.

The Role of Darkness in the Autoflower Light Cycle

Another question that often arises is: do autoflowers need darkness? While autoflowers can technically grow under 24 hours of light without experiencing any adverse effects, some growers believe that a period of darkness is beneficial. 

Dark periods can provide a resting period for the plant, potentially promoting healthier growth. Additionally, slightly reduced light exposure can help manage your energy costs. So, while autoflowers don’t need darkness like photoperiod plants, it can still be a beneficial part of your light schedule for autoflower.

Germinating Autoflower Seeds

When it comes to germinating autoflower seeds, the initial light cycle is crucial. Providing your seedlings with a gentle introduction to light can help establish robust early growth. An 18/6 light schedule (18 hours of light, 6 hours of darkness) is generally recommended for this stage. This light schedule allows your young plants to adapt without becoming overwhelmed.

Nurturing the Marijuana Plant’s Growth Stage

Light remains essential as your autoflowers transition through their various growth stages. You can adjust the light intensity and duration based on the marijuana plant’s growth stage. For instance, during the vegetative stage, you might want to opt for a slightly longer light period (20/4) to promote more vigorous growth.

Cannabis Cultivation Tips: Harvesting and Fertilization

There are various cannabis cultivation tips that can also help you maximize your harvest. Some growers reduce the light exposure in the last couple of weeks before harvesting, believing it can help increase resin production.

Another crucial aspect of cultivating autoflowering cannabis plants is fertilization. Combining the ideal autoflower light cycle with proper nutrition can drastically improve yields. Remember, autoflowers typically require less feeding than their photoperiod counterparts, so be careful not to overdo it.

The Bottom Line

Autoflower light schedules might not be as complex as those for photoperiod strains, but they’re still a critical factor in your plants’ overall health and productivity. By understanding and implementing the best light cycle for autoflowers, you can optimize your yield and enjoy the rewards of your autoflower weed plants.
