GrowMax Mega Grow 1000 – Reverse Osmosis System
The Mega Grow 1000 RO System removes most impurities from tap water at a rate of up to 1000 litres per day, or 40 litres per hour, and is ideal for hydroponic and general gardening.
Removing minerals and salts from water allows plants to take up more nutrient and can help to avoid nutrient lockout.
These RO Systems also remove up to 99% of Chlorine, this is important as Chlorine is not good for soil life!


Removes or reduces: up to 95% of Mineral Salts, Heavy Metals, Chloramines, Nitrates, Nitrites, Sediments, Sand, Oxides, Herbicides, Pesticides and Volatile Organic Pollutants (Chemical Contaminants, Benzene, Oils, Trialomethanes, Detergents, PCBs).
Also removes up to 99% of Chlorine and sediment up to 5 microns.

The Mega Grow 1000 comes with all the pipework and fittings necessary for use, once connected to a water supply, the product water can be collected in a water butt.
It is always best to use RO produced water straight away or add nutrient to help stabilize pH.
The amount of water produced is dependent on the water temperature, quality and pressure of the water supply. If the water pressure is low, a GrowMax Booster pump can be added to improve the rate of production.
GrowMax recommend that the carbon(green) and sediment(white) filters are changed every 6 months, and the RO membrane is changed every 6 months to 2 years dependent on use and mains water quality.
The Mega Grow 500 uses 2 x carbon filters and 1 x sediment filter.
