Plant growth regulators (PGR) are a chemical or mix of chemicals that make a plant change beyond its natural physiological growth actions, through the cells, organs and tissues. It does this by either slowing down the rate of growth or maturation; speeding up the rate of growth or maturation; or altering the natural behaviour of a plant. Note that this does not include any substances which are intended as a plant nutrient, including trace elements, plant inoculants or nutritional chemicals.

PGRs will control plants if used in the right mixtures at the correct dosages, considerably improve the desired factors. PGRs can help a plant to produce more flowers and fruits and assist in producing even consistent flowers and fruits. They can help you keep plant height consistent and reduce the time it takes for a plant to produce its flowers and fruits. They can also make a plant less susceptible to fungi, diseases and pests.
