Water is one of the most important elements in any hydroponic system. Unfiltered tap water, well water, and rain water have the potential to cause problems for your plants. It is vital to eliminate all the problem-causing chemicals, minerals, toxins, and bacteria in your water supply before introducing it to your hydroponic system. In most cases, the best solution for water quality issues is a reverse osmosis (RO) system. RO systems reduce over 99% of dissolved minerals, chlorine, and contaminants. Fresh Water Systems offers RO systems, UV purifiers, sediment filtration, and many other products to help ensure your plants receive clean, pure water.
