Description

Plagron Alga Grow Plagron Alga Grow, Both amateur and professional growers want to see a result as soon as possible. To spur plants on to unprecedented feats, nature needs to be given a helping hand - in a natural way of course. Plagron has therefore developed the Alga-Grow, especially for the growth phase. Alga-Grow contains a precisely balanced ratio of nitrogen, phosphates and potash that the plants can directly absorb and which optimises growth on a purely natural basis. The nitrogen in Plagron Alga-Grow promotes even, optimum growth. The phosphor promotes improved root development and an initial onset for a strong, rich flowering process. Potash promotes the transportation of nutrients through the entire plant and enhances general resistance. With the extremely nutrition-rich Plagron Alga-Groei, you tackle the desired development literally by the roots. A multiplicity of growth-stimulating additives enables the treated plants to develop optimally within an accelerated time frame. Plagron Alga-Grow is an organic, liquid N-P-P nutrient, which the plant can directly absorb. Plagron Alga-Grow contains an abundance of nitrogen (4%), phosphor (6%), potash (8%), amino acids, trace elements and minerals that not only promote exuberant growth and root development but also simultaneously provide extra residence and stimulate the natural formation of chlorophyll.
