Rockwool insulation is superior. If the fireproof blanket insulation into a lot higher within the drainage than what was fed to the crops, then the EC in the feed solution needs to be dropped back – that is widespread below hot rising conditions when the crops may be taking up much more water than vitamins, therefore concentrating the nutrient resolution. ROCKWOOL’s products manufactured at the Ploiești facility will mostly be used for making insulation used in building, and mostly be sold in Romania as the country is one of Europe’s largest insulation markets.
