About wet/dry cycles

Cannabis cultivation is an intricate process that requires a deep understanding of the plant's needs. One such aspect of cannabis growing is maintaining the appropriate wet and dry cycles. This article will discuss the importance of wet and dry cycles in cannabis growth and how to manage them effectively.

Introduction to Wet and Dry Cycles​

The wet and dry cycles refer to the periods of hydration and dehydration for the cannabis plant. These cycles play a crucial role in the plant's overall health and development, as they help in nutrient absorption, root development, and maintaining a healthy environment for the plant.

Importance of Wet and Dry Cycles​

Wet and dry cycles are essential in cannabis cultivation for several reasons:

  1. Nutrient absorption: The plant absorbs nutrients more efficiently during the wet cycle, as the water helps in dissolving and transporting essential elements to the roots.
  2. Root development: The dry cycle encourages the roots to grow deeper in search of water, promoting a more robust and extensive root system.
  3. Preventing root rot: Overwatering can lead to root rot, which is a common issue in cannabis cultivation. Proper wet and dry cycles help prevent this problem by allowing the roots to dry out and breathe between watering sessions.
  4. Disease prevention: Maintaining an ideal wet and dry cycle helps prevent the growth of harmful pathogens, such as molds and fungi, which thrive in damp conditions.

Understanding Cannabis Watering Needs​

Different factors affect the watering needs of cannabis plants, including:

  1. Stage of growth: Cannabis plants require different amounts of water during various growth stages. Seedlings and young plants need less water, while mature plants and those in the flowering stage need more frequent watering.
  2. Pot size: Smaller pots dry out faster than larger pots, requiring more frequent watering.
  3. Growing medium: The type of growing medium can impact the wet and dry cycles. Soil tends to hold more water and takes longer to dry out, while coco coir and other soilless mediums may require more frequent watering.
  4. Temperature and humidity: Higher temperatures and low humidity can cause the growing medium to dry out faster, increasing the need for frequent watering.

Managing Wet and Dry Cycles​

To manage the wet and dry cycles effectively, follow these steps:

  1. Check the moisture level: Use your finger or a moisture meter to check the moisture level of the growing medium. Ideally, you should water the plants when the top inch of the medium is dry.
  2. Use the right watering technique: Water the plants slowly and evenly, allowing the water to reach the roots without causing runoff. This ensures proper hydration and prevents overwatering.
  3. Monitor plant health: Keep a close eye on your plants' health and appearance. Signs of overwatering include yellowing leaves, drooping, and slow growth, while underwatered plants may exhibit wilting and dry, crispy leaves.
  4. Adjust watering frequency: Based on the factors mentioned earlier, adjust your watering frequency to maintain the ideal wet and dry cycles for your cannabis plants.


Maintaining proper wet and dry cycles is essential for successful cannabis cultivation. By understanding the factors that affect watering needs and monitoring your plants' health and appearance, you can provide your cannabis plants with the optimal environment for growth and development. Remember that each plant is unique, and the key to successful cannabis cultivation is patience, observation, and adaptation.

Over watering is probably the most common mistake a grower makes...We love to baby our plants.
