For intensive growth, flowering and formation of rosettes of Petrocosmea and Primulina plants


A multi-component, comprehensive, specialized mineral fertilizer designed for soil fertilization of Petrocosmea and Primulin plants. "Petrocosmea.com EXPAND IT!" is a completely water-soluble, concentrated fertilizer, the composition of which has been selected so as to stimulate the vegetative growth of plants, flowering induction and proportional formation of leaf rosettes in a balanced way. Thanks to the unique proportion of nitrogen, phosphorus and potassium N: P: K - 12:10:12 and an additional portion of magnesium and calcium, it provides intense leaf coloration and symmetrical growth of rosettes.

 Suitable for fertilizing plants of the genera Petrocosmea, Primulina and other related species. The fertilizer can be used in hydroponic cultivation and other cultivation systems without a traditional substrate. Foliar fertilization of plants is possible, but we do not recommend using this form of fertilization for Patrocosmea plants.
