B Esentials/Oligo Spectrum 5L

An essential complement for all fertilizers. 

Oligo Spectrum is a unique product: it is a comprehensive concentration of micro nutrients in a chelated form, plus essential sub micro particles and an organic buffer. It is used as a complement to the nutritive solution in soil and water culture, as well as in foliar spray.All the elements included in Oligo Spectrum  are chelated : a chelated element is released to the plants only when it becomes less abundant in the nutritive solution.

This way, the chelate not only maintains a stable level of the nutrient, but also it protects the plant from an unwanted accumulation of harmful salts.
