Tap Water vs Reverse Osmosis (RO) Filters

Serious gardeners have long realized how important pure water is to the success of their crops. Using purified water allows you to push your plants to their limits, increasing growth capability and yield. After all, water is the very essence of hydroponics and therefore the most important component to a healthy garden.

If you look at the top of most nutrient manufacturer’s feed charts, you will notice that they require starting with 0 parts per million (ppm) water for the nutrient solution. Without this pure base, it is much more difficult to dial in the ppm of your formula while still ensuring that you have the proper amounts of each component vital to healthy growth. If the feeding chart says to bring the nutrient solution to 1200 ppm and you are starting with water that is at 500 ppm, what do you do? It is hard to adjust for it in the nutrient formula you are trying to perfect.

Tap water also contains many elements which are also toxic to plants.  Besides chlorine and chloramines, many other impurities and toxins can be found in drinking water, including sodium, pesticides, iron oxide, volatile organic compounds, and industrial wastes/pollutants.  These elements are harmful to plants and can react with the nutrients in the fertilizer solution, locking out key nutrients to plants and causing mineral deficiencies.

Organic gardeners using compost teas or bio-extraction solutions should only use purified water. When gardening with living microorganisms such as beneficial bacteria, fungi and nematodes, you must use contaminant-free water in order for these organisms to survive and flourish.  Tap water will destroy and inhibit many of these beneficial organisms.

To effectively remove chloramines and other contaminants, water should be passed through a Reverse Osmosis (RO) System (a Bountea Hydrate filter will also work for this process). RO water systems can remove up to 99% of chlorine, heavy metals, chemicals, sediment, and other dissolved solids.  RO systems are a must-have for any serious gardener that wants to increase the potential of their crop.

For the highest quality and most effective equipment, we recommend using a reverse osmosis system from either Hydrologic or GrowoniX.  These RO systems are specifically designed for hydroponic growers and come ready-to-go right from the box, all you need to do is hook up the supply and drain lines and you are ready to start producing purified water for your plants.  These systems ensure super high flow rates with minimal wastewater, and are extraordinarily compact and mobile.
