Environmental Sensors for Cannabis Growers: Climate and Root Zone
Environmental sensors communicate data about the growing environment and are essential for precision-focused cannabis cultivation in controlled facilities.
Climate sensors measure variables like temperature, humidity, CO2, and light levels and root zone sensors measure moisture content or WC (water content), EC (electrical conductivity), and substrate temperature. Adjusting the climate can help maintain an optimal VPD (Vapor Pressure Deficit) range, which is critical to the plants’ abilities for transpiration and nutrient uptake.
Proper VPD also enables cannabis plants to regulate CO2 consumption and prevent condensation. Monitoring the root zone, on the other hand, lets you know how your plants are absorbing nutrients and helps you dial in your irrigation strategy. Maintaining a consistent environment is key to optimal cannabis growth and output. But detection of all critical levels is the first step.

What are the benefits of cannabis cultivation sensors?
Implementing environmental sensors can help greenhouse and indoor growers achieve a more consistent and predictable growing environment. By optimizing the environmental conditions, cultivators can increase cannabis production, improve quality, boost efficiency, and reduce energy costs.
For example, by monitoring and controlling temperature and relative humidity levels, growers can prevent mold and other plant diseases from developing. By monitoring and controlling CO2 levels, growers can enhance plant growth and increase yields.
Root zone sensors (or substrate sensors) are essential tools for monitoring the water content (WC) and nutrient levels of the growing media. Cannabis cultivation sensors provide growers with precise readings of the substrate or soil moisture, temperature, and electrical conductivity (EC) levels in their grow room. By monitoring the readings, growers can adjust irrigation and nutrient delivery in pursuit of higher yields and quality. For a deep dive into EC, check out our Advanced Guide to EC.
