Plagron Vita Race 1 l is an iron-containing spray for the growth phase and the first three weeks of the flowering phase. Iron is an important component for the formation of chlorophyll, which stimulates photosynthesis and gives the plant a healthy appearance. This promotes growth and flowering for an optimal end result. Vita Race is suitable for peat and coco substrates, but requires flushing of irrigation systems after use. Not suitable for hydroponic cultivation methods.
