Plant Growth Regulators

Commercial growers of flowering plants in the deep south face problems with cloudy conditions, heat and humidity. Most of the time these factors cause plants to stretch in production, making it harder to produce the best quality, and also causing problems in shipping where compact growth is desired. Plant growth regulators act like plant hormones to either stimulate branching, reduce stem stretching, increase flowering, or decrease flowering.
