Formerly known as Essentials!
Whilst primary and secondary elements are always included in plant nutrients, some micro and sub- micro nutrients are not, despite laboratory tests demonstrating an important overall improvement in plant health and resistance to pests when those elements are added. 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.
All the elements included in GHE Oligo Spectrum comply with the European regulation on organic agriculture, and as in our other nutrients, all possible elements in Oligo Spectrum are chelated for superior stability and performance.
How to use Oligo Spectrum:
Dilute to use as a foliar spray or add to water or nutrient solution.
DO NOT USE WITH GHE NUTRIENTS – they already contain a full trace element spectrum.
- Solution: 2 ml/L in Hydroponics, 3 ml/L in soil
- Foliar spray: 2 ml/L
