Bloom Enhancers are supplements added to an existing nutrient regimen for the purpose of increasing flower size, density and quality. The majority of such products are based on providing additional phosphorous and potassium, which are thought to be the primary drivers of the metabolic processes associated with floral production. Some bloom enhancers may also include calcium, magnesium, sulfur, and amino acids for similar purposes. Other products take advantage of microbiology to mobilize existing supplies of phosphorous. Yet another line of thought and products function to reduce internodal distance, aka improved stacking, and so generate more compact blooms. Relatively new to this category, are products expressly devoted to increased trichome and terpene production.
