How Do Reverse Osmosis Water Filters Help Hydroponic Gardeners?

Reverse Osmosis (RO) water systems optimise hydroponic gardens. RO water filters eliminate up to 95% of all of salts and heavy metals as well as immediately eliminating 99% of chlorine and sediments down to 5 microns!

RO water filters utilise a semi-permeable membrane to remove larger particles such as bacteria, molecules and ions from the source water (usually tap water). RO membranes retain impurities on one side of the membrane, while the pure water freely passes to the other side through the pores in the membrane.

Eliminates or Reduces: Salts, heavy metals, chloramines, nitrates, nitrites, chlorine. Sediment; dirt, rust, oxidation. Herbicides and pesticides, volatile organic contaminants. Chemical contaminants, benzenes, toluene, oils, THM's, detergents, PCB's)

The Power Grow unit produces 500 L/D (20 L/H) whilst the Mega Grow unit can produce up to 1000 L/D (40 L/H).

Reverse Osmosis water filters allow you to create a blank canvas, producing near zero ppm pure water, devoid of most dissolved salts, straight from the tap. Mains tap water can contain chlorine, chloramines, copper, nitrates, nitrites, phosphates and silicates. When used untreated, straight tap water can be harmful to the beneficial fungi, microbes and bacteria in soil and hydroponic applications. Using RO water as the base for your nutrient solution, leads to faster growing, healthier plants.

Should I Use An RO FIlter?

To find out if you could benefit by using an RO filter for your watering requirements, simply measure your tap water supply with a TDS meter. If your tap water is greater than 10 ppm, you will likely see improved results from RO water. The higher the reading, the more benefit you'll gain. Setting your reservoir water profile to near zero ppm gives you more confidence your feeding the correct nutrient levels when you mix your nutrients. EC/CF measurements for nutrient mixes are a lot more accurate with near-zero ppm base water. Improved accuracy means you can keep better records and repeat nutrient mixes time after time for future grows.

How Often Should You Change RO Filters?

We recommend you change your filters once every six months to maintain the reverse osmosis filters efficiency.

How to Use

Garden tip:

  • The RO filter unit operates with mains pressure between minimum 40 psi to a maximum of 80 psi. Water pressures over 80 psi require you to fit a pressure regulator to reduce pressure to an acceptable level.

  • 1. Simply install the inlet pipe onto a garden tap or faucet and connect this to the unit with a length of 3/8" tubing.

    2. You can now connect the unit to your garden hose using the outlet and another piece of 3/8" tube.

    3. Alternatively, you can run the 3/8" tube directly to your garden or a reservoir for storage for later use.

    4. Discard the first 15 minutes worth of water when the system is new or if filters have been replaced, the PPM and pH of the water will stabilise over the first 24 hour period.
