Abbreviation for Plant Growth Regulator. Synthetic or natural substances that are used to alter the growth and development of cannabis plants. PGRs can influence various aspects of plant growth, such as branching, flower size, root development, and flowering time. While some PGRs are naturally occurring and can benefit plant health, others are synthetic and controversial due to potential health risks and negative impacts on cannabis quality.
