How Much Watering Does Your Canabis Plant Need:
A Comprehensive Guide

Updated: June 11, 2023

Cannabis plants, like any other plant, require water to grow and thrive. However, it is crucial to understand the right amount of water your cannabis plant needs, as overwatering or underwatering can be detrimental to the plant’s health. In this article, we’ll provide a comprehensive guide on how much watering your cannabis plant needs.

Understanding Water Requirements of Cannabis Plants

The amount of water your cannabis plant needs depends on several factors such as the size of the plant, the stage of growth, and the type of soil or growing medium. Generally, younger plants require less water than mature plants as they have smaller root systems and are not as developed.

Cannabis plants also require more water during their vegetative stage compared to their flowering stage. During the vegetative stage, the plants are actively growing and require more water to support their growth. In contrast, during the flowering stage, the plants focus on producing buds and require less water.

Finally, the type of soil or growing medium can also impact how much water your cannabis plant needs. Well-draining soil or growing mediums help prevent overwatering by allowing excess water to drain away from the plant’s roots.

Signs of Overwatering and Underwatering

Overwatering or underwatering your cannabis plant can lead to several problems. Overwatering can cause root rot, which can damage or kill the roots of your cannabis plant. On the other hand, underwatering can cause stunted growth and wilted leaves.

To avoid these issues, you need to know the signs of overwatering and underwatering. Signs of overwatering include yellowing leaves, droopy stems, and a foul odor from the soil or growing medium. Signs of underwatering include dry soil or growing medium, wilted leaves, and slow growth.

How Much Water Does Your Cannabis Plant Need?

The amount of water your cannabis plant needs depends on several factors. Here are some general guidelines to follow:

  • Water your cannabis plant once every two to three days during its vegetative stage.
  • Water your cannabis plant once every three to four days during its flowering stage.
  • Use about 1 gallon of water per 1 square foot of growing space.

It’s important to note that these are general guidelines and may vary depending on your specific growing conditions. Always monitor your plants for signs of overwatering or underwatering and adjust your watering schedule accordingly.

Tips for Watering Your Cannabis Plant

Here are some tips for watering your cannabis plant:

  • Always use room temperature water as cold water can shock the roots.
  • Make sure the soil or growing medium is dry before watering.
  • Water slowly and evenly around the base of the plant.
  • Avoid getting water on the leaves as this can lead to mold or mildew growth.
  • Use nutrient-rich water during the vegetative stage but avoid using nutrient-rich water during the flowering stage.
