Growing cannabis can be a tricky endeavor, but autoflowers make it a bit easier for novice growers. These plants have a set life cycle, meaning they will flower regardless of the amount of light they receive. To ensure the optimal conditions for your autoflowers, it is essential to follow an Autoflower Temperature and Humidity Chart to monitor and maintain the ideal temperature and humidity levels throughout the different growth stages. With the right conditions, you can maximize your autoflower yield and achieve a bountiful harvest.

Understanding Temperature and Humidity Requirements

Autoflowers typically thrive in a slightly cooler environment than photoperiod strains. The optimal temperature range for growth is between 68-78°F (20-26°C). A temperature above 80°F (27°C) can cause stress to the plant and negatively impact growth.

Similarly, humidity levels play a key role in the health and development of autoflowers. During the vegetative stage, the ideal humidity range is between 40-60%. As the plants enter the flowering stage, the humidity should be lowered to around 40% to prevent mold and other pests from flourishing.

Maintaining Consistency

It is important to maintain consistency in temperature and humidity levels to ensure steady growth. Fluctuations in these factors can lead to stress and slow down development. Investing in a quality thermometer and hygrometer will help you monitor and maintain ideal conditions.

Following the ideal temperature and humidity ranges for autoflowers is critical for ensuring a bountiful harvest of healthy, robust plants. Temperature and humidity control plays a key role in the growth and development of autoflowers, as well as the overall health of the plants. Incorrect temperature and humidity levels can lead to stress, slow down development, and even cause mold and other pests to flourish.

Maintaining consistency in temperature and humidity levels throughout the autoflower’s different growth stages ensures steady plant growth and development. This results in better yields and more potent buds.


By keeping a close eye on temperature and humidity levels and maintaining consistency, you can ensure a bountiful harvest of healthy and robust autoflowers.
