Tired of purchasing RO or distilled water for your Grobo or other hydroponic systems? This is the RO water filter system you've been looking for.
The Grobo RO pumpless water purifier installs under your sink and lets you have clean reverse osmosis water on tap. No more carrying heavy jugs of water home!
We recommend using RO or distilled water in your Grobo as it doesn't contain anything the plant doesn't need, such as chlorine or fluoride. This will allow your plant to thrive!
What is Reverse Osmosis?
Reverse Osmosis is a water filtration process that removes harmful contaminants from your tap water. The water is under pressure while going through various filters that result in pure, clean drinking water.
RO water has an EC of 0, meaning that it contains no nutrients. This is perfect for your Grobo grow box or other hydroponic setups as you provide your plant with perfectly clean water. Your Grobo will then add in the nutrients your plant needs.
- 5-stage filtration (PP & GAC & CTO & RO & T33)
- Integrated manifold, no tubes, no fittings, no leakage.
