Flowering additives are formulated to increase flower and bud production in healthy plants. These additives are generally used from the onset of budding until flowers or fruit are fully formed. Bloom additives primarily contain phosphate (“P”) and potassium (“K”). These elements are more in demand during the flowering and fruiting phase. Organic plant-growth-regulators such as auxins, gibberellins and cytokinins are also useful components of flowering additives (see A Guide to PGRs in the Grow Room).
