Non-Destructive Detection & Monitoring of Mold on Cannabis with Hyperspectral Imaging

Mold is one of the most common problems that cannabis growers and sellers face. Catching a mold infection early can mean the difference between a minor inconvenience and a devastating loss of valuable crops. By the time a mold infection is visible to the naked eye, it may be too late. Mold can cause allergic reactions and in some cases even death.

Hyperspectral imaging is poised to make a significant impact on the cannabis industry because of its ability to simultaneously utilize the value of both spatial and spectral information. Current cannabis testing methods rely on spot sampling and do not capture enough data to measure the variability within a sample. Hyperspectral imaging is non-destructive and enables real-time test results, allowing rapid and complete product testing without the need to remove samples from product and prepare those samples for testing.

Applications include determining cannabinoid concentration, moisture content testing, mold detection and monitoring, improved foreign-object detection in cultivation, enhanced testing for regulatory and law-enforcement reasons, and monitoring cannabis plant growth
