What makes Plant System E15 so special?
Thanks to its special formula, E15 contains only bivalent iron, which can be absorbed immediately by plants – similar to how glucose is absorbed directly into the bloodstream in humans. Additionally, so-called chelates ensure that the nutrients remain available for a long time. The clever blend of immediately effective iron (50%) and long-term stable iron (50%) guarantees ideal immediate and long-term effects. This promotes photosynthesis and ensures sustained, strong plants.
