The Growonix EX series of reverse osmosis systems was designed, hand built, and tested in the USA. GrowoniX went back to the drawing board to provide all the value of their GX line of water filters, at a price point that allows any grower to provide their plants with clean water.

The GrowoniX EX line has stripped costs down to a level that provides growers with everything they need and nothing they don't. If you are looking for a budget friendly water filtration system that doesn't skimp on quality or efficiency, the EX line is perfect for you.
