HYDRO FLORES A&B (HW)CANNA HYDRO is the nutrient for cultivating plants in run to waste systems, in which the drainage water is not returned to the nutrient tank but drains away. The plants get fresh nutrients at each feed which minimises the risk of diseases. The substrates used in these systems are mostly inert so all nutrient is available to the plant. CANNA Hydro Flores is used when flowering begins and accounts for less nitrogen and more potassium and phosphorous
