Water started from a reverse osmosis system provides a constant water quality. Nutrients can be better controlled without having to worry about what is in the water source at the beginning of the irrigation process.

For this reason, most growers benefit from a greenhouse reverse osmosis system. Growing with good water and adding nutrients at the grower's discretion make growing more calculable and can easily be duplicated for consistency. Not having iron, manganese, calcium or magnesium makes setting up the nutrient solution easier since the fertilizers are not reacting with the impurities in the water. The only nutrient minerals that are added to the irrigation water are the ones that are an advantage to the plant.

Reverse Osmosis Systems are the most reliable solution to correct bad source water quality. Growers have a need for pure water that is free of common contaminants from wells or municipal supplies including lead, mercury, chlorine, VOCs, unwanted minerals. Not only can these unwanted substances affect nutrient uptake, but they can also affect crop qualities like aroma and flavor which could greatly diminish the value of the plants grown and harvested.

Basically, the reverse osmosis filter is a membrane through which water is pumped, filtering water at a molecular level. Most dissolved solids can't get through the membrane. This means that the water coming out of the filter is much closer to pure water - without any contaminants.

RO is purified using osmotic pressure with a membrane, as opposed to using a filter like many other water purification methods. This allows the water to be purified of nearly all contaminants. With Reverse Osmosis water, you know exactly what you're dealing with as there is nothing in the water that you didn't put there yourself.
