Heavy metals

Toxic substances that are absorbed by plants during growth from nutrients, fertilizers, water and soil in the hydroponic cultivation and can trigger a whole range of health problems at low concentrations. Most cannabis regulations require producers to test for heavy metals and severely limit the amount available in the final form. Commonly tested heavy metals include arsenic, nickel, lead, mercury, copper, zinc, chromium and cadmium.
