Vegetative and reproductive stage lighting interactions on flower yield, water use efficiency, terpenes, and cannabinoids of Cannabis sativa
Abstract Cannabis is among the most water-demanding crops, facing ongoing expansion and water use regulations. This study evaluated the effects of greenhouse sunlight plus increased LED supplemental lighting on flower yield, water use (WU), [...]
Illuminating Cannabis sativa L.: The Power of Light in Enhancing C. sativa Growth and Secondary Metabolite Production
Abstract Light is crucial for higher plants, driving photosynthesis and serving as a powerful sensory signal that profoundly modulates growth, development, physiological functions, hormone activation, and biochemical pathways. Various light parameters—quality, intensity, composition, and [...]
LED spectra and defoliation independently shape canopy architecture and cannabinoid yield in indoor Cannabis cultivation
Abstract Cannabis growers often use light spectra and defoliation regimes to alter the growth of their plants. While several studies consider the impact of these practices separately, there are no reports of how these [...]
Crop steering through osmotic stress can reduce height but reduced yield in medical Cannabis
Abstract Background Precision water stress, achieved via osmotic stress, has the potential to control plant size and improve crop quality without reducing yield, but results across species and cultivars have been inconsistent. Methods This [...]

Accumulation of somatic mutations leads to genetic mosaicism in cannabis
Abstract Cannabis (Cannabis sativa L.) is typically propagated using stem cuttings taken from mother plants to produce genetically uniform propagules. However, producers anecdotally report that clonal lines deteriorate over time and eventually produce clones [...]
Somatic Mutation Accumulations in Micropropagated Cannabis Are Proportional to the Number of Subcultures
Abstract Advancements in micropropagation techniques have made it easier to produce large numbers of cannabis clones, but these methods may also introduce genetic instability over successive generations. This instability often manifests as somaclonal variation, [...]
Impact of Electron Beam Treatment and Storage Duration on Microbial Stability and Phytochemical Integrity in Hemp Flowers
Abstract This study compared the effects of storage time and electron beam (EB) irradiation on microbial counts and chemical stability of dried flowers from two hemp cultivars over 12 weeks. Cannabinoid and terpene content, as [...]
Automated IoT-Based Monitoring of Industrial Hemp in Greenhouses Using Open-Source Systems and Computer Vision
Abstract Monitoring the development of greenhouse crops is essential for optimising yield and ensuring the efficient use of resources. A system for monitoring hemp (Cannabis sativa L.) cultivation under greenhouse conditions using computer vision [...]
