The Growmax Mega Grow 1000 Reverse Osmosis Filter is a 3 stage RO filter that can deliver up to 40 litres per hour of low EC, nearly pure water – total output of the filter is around 1000 litres per day.
The system effectively removes up to 95% of:
Salts, Heavy Metals, Chloramines, nitrates, nitritets, Chlorine. Sediment; dirt, rust, oxidation. Herbicides and Pesticides Volatile Organic Contaminants (Chemical Contaminants, Benzenes, Toluene, Oils, THM’s, Detergents, PCB’s).
Using RO water has 3 main benefits:
1. Removing the chlorine lets the soil biota flourish, especially if you are using bacterial or microbial additives.
2. Stable PH. Ro Water has a ph of around 6.5, a good starting point for most plants.
3. Allows for more precise control of fertilization. By removing the background EC of you tap water, you deliver your plants a more balanced nutrient solution.
The filters on the Mega Grow 1000 last for around 12,000 litres or 6 months. We list the replacements in the dropdown above, along with a replacement membrane – this will need changing approx. every 9 months.
Other accessories available include a float switch and booster pump for use where the input to the RO filter is less than 40 psi.
