Your filter will eliminate almost all water impurities!

You'll get a more efficient nutrient feed and a more stable pH while enhancing nutrient uptake - harmful Chlorine is removed.

If you're growing in soil, healthy bacteria and microorganisms will thrive (again, no harmful chlorine).

Overall, you should get more developed plants, healthier fruits & stronger roots.

If you use a humidifier, your reflectors, carbon filters and bulbs will be better maintained and longer lasting - an RO filter prevents mineral deposits.

Pure Water Production

POWER GROW 500 RO Unit - produces up to 500 litres of pure water a day (20 litres an hour)

Do you Need a Booster Pump?

RO filters need a water pressure of at least 40 PSI.

Tap water pressure varies, so you may need a booster pump - it'll raise your water pressure by 15 - 50 PSI, depending on your tap water quality.

For best results, aim for 60 - 80 PSI.

We Recommend

1. If you use a humidifier, use an RO filter to protect your bulbs, reflectors and carbon filter.

2. Replace your carbon filter and sediment filter every 3 months - this'll prolong the life of the RO membrane in your filter
