Phyto Monitoring of Cannabis
With climate change leading to increasingly erratic weather patterns, farmers are struggling to create irrigation regimens that can account for environmental factors and sudden weather changes. Overwatering plants can affect the quality of the final product and under watering can lead to a smaller yield. Cannabis plants are particularly difficult to regulate as they are impacted by so many factors.
An experiment conducted by SupPlant indicated that although overall crop yield is not significantly affected by irrigation, the types and percentages of cannabinoids found in the plant are. So while quantity may not be greatly affected by irrigation in cannabis’ case, a quality most definitely is. With SupPlant’s autonomous irrigation technology, cannabis growers can regulate the irrigation that their plants receive to achieve the desired concentration of cannabinoids
The goal of the experiment is to develop a method for assessing plant stress using electronic sensors, installed on plants in comparison with the irrigation regime and meteorological data. For this, three irrigation levels were organized: 100%, 75%, and 50%. The amount of water, typically used by the farmer for irrigation was taken as 100%.
To assess the behavior of the plant under different levels of irrigation, we used sensors of stem growth rates and leaf temperature. To monitor the irrigation regime and soil moisture levels, soil volumetric moisture sensors were installed in the root zone of the plants that were used. The experiment was supported by data from a meteorological station, measuring air temperature and humidity, as well as photosynthetically active radiation (PAR).
