Why Soil Moisture Matters In Cannabis

Healthy soil moisture levels are the foundation for vibrant growth, optimal nutrient uptake, and high yields. 

Let’s break down the key reasons soil moisture matters and how it impacts your plants.

  • Overly damp soil: When the soil is too wet, it will suffocate the roots by cutting off their oxygen supply, causing root rot and fungal infections. 

This stops growth and, if not corrected, can kill your plants entirely. In addition, damp conditions can encourage pests and molds to grow, further harming your plants and requiring intervention.

  • Overly dry soil: Soil that dries up too much prevents nutrient uptake and slows down photosynthesis, leaving plants weak and unable to thrive. 

Prolonged dryness can also lead to hardened soil structures, making it difficult for roots to penetrate and expand, thus limiting the plant’s growth potential.

  • Achieving balance: The perfect moisture balance fosters a healthy root system, supports efficient nutrient uptake, and creates an ideal environment for strong growth and higher yields. 
  • Long-term benefits: A consistent level of moisture management lessens the threat of water-stress-related stunted growth, so your plants will always thrive during the cycle.

    Now we will discuss the factors that affect soil moisture in cannabis.

Factors That Affect Soil Moisture In Cannabis

Environmental factors are important in determining soil moisture levels because they affect the water availability for crops and their growth. 

Understanding this enables growers to vary their irrigation patterns to maintain proper growing conditions. Here are some factors that affect soil moisture in your cannabis plant.

  • Temperature and humidity: High temperatures accelerate evaporation rates, causing soil to dry out quickly, while low humidity levels exacerbate the drying process. 

Conversely, cooler temperatures and higher humidity slow evaporation, requiring less frequent watering.

  • Composition of the soil: Sandy, loamy, or clay soils are common. The composition of the soil mainly affects its water retention and drainage capacity. 

Sandy soils drain fast, so the plant needs more frequent watering. Clay soils retain water and can easily be compacted.

  • Pot size and material: The smaller the pot, the faster the soil dries up because there is little soil. The bigger it is, the longer the soil will maintain moisture. 

The material of the pot also plays a role in how the water will diffuse or fall out. 

For example, ceramic and plastic versus fabric, which promotes good aeration but dries out faster than plastic.

  • Light exposure: Higher exposure to bright light, whether sunlight or grow lights, will increase the soil temperature and speed up evaporation. 
  • Air circulation: Good air circulation helps dry the soil evenly, reducing the chances of waterlogging in specific areas. However, excessive air movement will speed up evaporation, necessitating more frequent monitoring.
  • Plant growth stage: Cannabis plants require different amounts of water depending on their growth stage. Seedlings require less water than mature plants at the flowering stage, which is the most water-intensive.

    Monitor these factors with soil moisture readings to develop an irrigation schedule promoting uniform and healthy growth during the growing cycle.

    So, how do soil moisture sensors improve your cannabis yield? Let us find out.
