Growonix High Rejection Membrane - 150+ GPD - For EX100/GX200 and GX300/400

Restore Purified Water Output - 150+ GPD Replacement Membrane

A worn membrane lets output drop and dissolved solids pass through, which makes nutrient mixing less predictable. This replacement membrane fits compatible Growonix systems and returns the unit to its rated purification performance. It is rated for up to 150+ gallons per day.

As a single replacement unit, it suits growers who service one system at a time, from home gardeners to commercial operations that keep spares on hand for scheduled maintenance.

Key Features & Benefits

• High rejection membrane — reduces dissolved solids in water used for hydroponic feeding.
• Polyamide thin-film composite construction — a membrane material common in reverse osmosis filtration.
• 2 x 12 in filter size — a defined size that matches the listed Growonix systems.
• Broad system fit — works with EX200, EX400, EX400-T, GX150, GX200, GX300 and GX400 units.

Who Should Use Growonix High Rejection Membrane

Frequently Asked Questions

Q: Which systems does this membrane fit?
A: It fits the Growonix EX200, EX400, EX400-T, GX150, GX200, GX300 and GX400. Confirm your system model before ordering.

Q: What does GPD mean?
A: GPD stands for gallons per day. It describes how much purified water a membrane can produce over 24 hours under rated conditions.

Q: What is a high rejection membrane?
A: It is a membrane built to hold back a larger share of dissolved solids from incoming water. That gives growers cleaner starting water for nutrient solutions.

Q: What is the membrane made of?
A: It is a polyamide thin-film composite membrane. This is a common material for reverse osmosis filtration.

Q: Does it tolerate chlorine?
A: Its chlorine tolerance is listed as 0 ppm. Use a carbon pre-filter stage to remove chlorine before water reaches the membrane.

Q: What temperature range can it run in?
A: The listed operating range is 50°F to 113°F. Keep feed water within that range.
