What kind of water should I use in Grobo?


#1

The Grobo system and nutrients are optimized for distilled or reverse osmosis water. These types of water do not contain any salts or minerals, allowing us to create the perfect recipe for your plant. Although not recommended, tap water can also be used and our system will know and adjust your nutrient solution automatically.


#2

Where do people normally get large amounts of distilled water? My supermarket only has 2 liter bottles.


#3

I recommend an 18 litre (5 gallon) jug. Most supermarkets will carry them, but not with the regular water bottles. Ask or check around the front of the store, near the registers. We also have several companies locally that will deliver. You can also use tap water, the Grobo One will know and adjust accordingly!
