The Plagron Hydro has been developed in the Netherlands, especially for cultivation in hydroponic systems, and when it comes to inert growing media, it's universally applicable.
The two-part A+B fertiliser with high nutrient concentration makes the EC and pH levels ideal. Plagron Hydro doesn't crystalise in the nutrient solution tank and absorbs immediately.
This fertiliser works so well because of the exceptional cooperation between the two parts. The A bottle contains calcium, which increases the plant's resistance to abiotic stress like drought, overwatering and temperature extremes. The B bottle contains magnesium, which helps the plant produce more chlorophyll and gives the plant more energy to grow.
Magnesium increases the production of chlorophyll and acts as a building material for plant growth.
