Grow Max 3000 reverse osmosis system designed for demanding indoor cultivation productions. Generates up to 3,000 L/day (approx. 125 L/h) of purified water, reducing EC, stabilizing pH and protecting substrate biology. Available at Hydroponics Blanes, online grow shop with discreet shipping and service from a trusted Grow Shop.

The Grow Max 3000 Reverse Osmosis System is designed for medium and large installations that require stable process water throughout the entire cultivation cycle.
Using two high-flow 500 GPD membranes and a pre-filtration train with block carbon, the unit reduces or eliminates up to 95% of mineral salts, heavy metals, chloramines, nitrates/nitrites, sediments, and volatile organic compounds; it also removes up to 99% of chlorine and 5 µm particles.
Improved irrigation water allows for precise nutrient solutions, minimizes overdosing, and keeps roots oxygenated with less risk of lockout. The production of 125 L/h supports reservoir filling, RDWC recirculations, and drip lines without bottlenecks.
The set includes a filter wrench, shut-off valve, garden hose connector, and color-coded tubing for organized installation in a grow room or technical cabinet. The recommended operating range is 25°C and 4–6 bar pressure with inlet water around 500 ppm TDS (≈0.7 EC).
With proper pre-filter maintenance (indicative: 40,000 L produced), the system maintains stable flow and rejection rates, a key component for a professional irrigation system seeking uniformity and repeatability when watering indoor crops.
Low-salt water enables clear recipes, promotes nutrient absorption, and reduces buildup in substrate, drippers, and pumps. In controlled environments, this translates to more uniform growth, less variability between benches, and simplified circuit cleaning. The 3,000 L/day output allows for planning mixing batches, reservoir top-offs, and room rotations without waiting.
To maximize efficiency, it is advisable to integrate an EC/ppm meter, pH meter, tank with float valve, transfer pump, additional sediment filters at the inlet if the water is cloudy, and 3/8” or 1/2” food-grade hose. A polishing post-filter and check valves help maintain quality. The entire range of irrigation accessories is available at Hydroponics Blanes with discreet shipping.
Technical tip: work with stable pressure within 4–6 bar. If the network is below this, consider a booster pump; very cold temperatures reduce effective flow.
