GHE Oligo Spectrum is a unique product: a comprehensive range of concentrated micronutrients in chelated form, plus essential sub-micro elements 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 in situations where metal addition to water can pose problems such as Aquaponics.
If you are using GHE nutrients then you are already providing this full spectrum, but if not, Oligo Spectrum gives you an effective way to complement your current regime and improve plant health and resistance to pests.
DO NOT USE WITH GHE NUTRIENTS - they already contain a full trace element spectrum.
