INTRODUCTION
OUR MISSION
Durability, Reliability, Eciency, Purity, and Conservation form the foundation on which we design
and build all of our products. Consistent and superior quality sets us apart from other manufacturers
and increases our value to you - our customer. Whether you are a hydroponics hobbyist, serious
enthusiast, or large-scale gardener, GrowoniX is committed to bringing you the best solution for
water purication systems.
WHAT IS REVERSE OSMOSIS?
Reverse osmosis (RO) is a ltration method that removes many types of large molecules and ions
from solutions by applying pressure to the solution when it is on one side of a selective membrane.
This ltering process ensures that the solute (waste water) is contained within the pressurized
chamber while the pure solvent (RO water) is allowed to pass freely through the membrane.
TUNED FOR GROWING - IN TUNE WITH OUR CUSTOMERS
Traditional RO systems have waste ratios of approximately 4:1, which means there are 4 gallons
of waste water produced for every 1 gallon of puried water. GrowoniX line of water lters achieve
waste ratios of 2:1 with the EX100 through GX400 and an astounding 1:1 ratio with the GX600 and
GX1000.
GrowoniX has created a complete product line that will address the needs of hydroponic operations
of all sizes. Our lters will signicantly reduce your water use while dramatically increasing your yields.

PRECAUTIONS
• Do not use unit with inlet water pressure exceeding 80 psi. If inlet water pressure is too high,
install water pressure regulator before the unit. Regulators and pressure limiters are available at
www.Growonix.com or your local plumbing supply.
• Keep unit away from direct light.
Direct light can cause algae and other biologicals to grow inside of the lter housings.
• Do not install unit near electrical outlets or electrical devices.
• Do not install in places where a leak can cause damage.
• GrowoniX EX Series RO water lters are rated using supply water that is 77°F, 475ppm, at 70psi.
Slower performance may be noted in areas with colder temperatures, higher water salinity, or
lower inlet water pressure.
• A minimum of 40psi is recommended to operate GrowoniX water lters. If your inlet water
pressure is too low, booster pumps can be used to increase pressure.
Pumps are available at www.Growonix.com.
• Do not use a ow restrictor other than the one included with your unit.
• Flow restrictors help tune the unit for proper waste ratio.
• Using bigger ow restrictors, or using the unit in areas with exceptionally dirty water,
