Examining the “Night Break” Method in Cannabis sativa Horticulture: Vegetative Daily Light Integral Affects Yield of Extractable Biomass in C. sativa
Abstract Cannabis sativa is a short-day (SD) plant, producing inflorescences when the daily scotoperiod (period of darkness) exceeds approximately 10 h of length. As such, the vegetative photoperiod is typically maintained at 16 to [...]
Soilless Growing Media for Cannabis Cultivation
Abstract Standardized pharmaceutical-grade cultivation of Cannabis sativa L. increasingly relies on soilless systems for precision, reproducibility, and regulatory compliance. This review examines the role of inert and semi-inert growing media in indoor cannabis production, [...]
Anthocyanin accumulation, inflorescence dry weight and total cannabidiol content have different temperature optima in Cannabis sativa
Abstract Background Limited information exists on how temperature affects phytocannabinoids and anthocyanin accumulation and inflorescence dry weight yield in Cannabis sativa. Understanding how temperature influences these traits is essential for refining cultivation practices, meeting [...]
Optimizing Growth Regulator Concentrations for Cannabis sativa L. Micropropagation
Abstract In this study, the effect of growth regulators on shoot proliferation and rooting were evaluated to develop an efficient micropropagation protocol for the Cannabis sativa L. cultivars ‘Cherry Soda’ and ‘Purple’. Apical meristems [...]

The Plant of Many Scents: Unraveling the Odorant Composition of Selected CBD Hemp Cultivars
Abstract This study presents the first comprehensive sensory-guided investigation into the odor-active compounds of dried hemp (Cannabis sativa L.) flowers. Using gas chromatography-olfactometry (GC-O) in combination with aroma extract dilution analysis (AEDA), 52 odor-active [...]
Cannabis glandular trichomes alter morphology and metabolite content during flower maturation
Summary The cannabis leaf is iconic, but it is the flowers of cannabis that are consumed for the psychoactive and medicinal effects of their specialized metabolites. Cannabinoid metabolites, together with terpenes, are produced in [...]
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, [...]
