Reverse Osmosis Units
Bestsellers
Reverse osmosis uses a semi-permeable membrane and high pressure to filter impurities from water. Only the solvent (in this case, water) gets through the membrane, while mineral salts and other dissolved compounds remain in the filter. Using reverse osmosis in plant cultivation increases the effectiveness of the used fertilisers because the filtered water is free of unwanted substances, which would otherwise increase the EC value.
The specialist in reverse osmosis is, without a doubt, Growmax Water.

Modern reverse osmosis units easily handle hard water as well as reliably clear it from any organic or chemical contaminants, bacteria or compounds like pesticides, insecticides or herbicides. Filters with activated charcoal catch (among others) 99% of chlorine molecules, which are commonplace in tap water and life-threatening to plants.
To get perfectly clean water, use an osmosis unit capable of total deionising. For example, the Growmax Water Power Gro can filter an impressive amount of 500 l of water a day without needing any electricity.
