HydroLogic Evolution-RO1000 Reverse Osmosis System 1000GPD

Inconsistent water quality is one of the most common — and most overlooked — sources of nutrient lockout and root stress in medium to large hydroponic operations. While smaller setups might utilize the HydroLogic Stealth-RO300, the Evolution-RO1000 addresses high-volume needs at the source, stripping up to 95% of total dissolved solids (TDS) and delivering a clean, predictable baseline that lets you build nutrient programs with confidence instead of guessing at what's already in the water.

This updated Evolution-RO1000 features an improved dry membrane design that boosts flow rate by 20% over the previous model, now producing up to 1,200+ GPD (50+ GPH) under standard test conditions (65 psi, 77°F source water, 500 ppm). Dual dry high-flow membranes work alongside the included ChloraShield™ carbon filter, which handles up to 100% chloramine removal. To maximize the lifespan of these membranes, many professional growers choose to install a HydroLogic 5 Micron Sediment Pre-Filter to capture larger particulates before they reach the system.

Built-in efficiency matters at scale, and the Evolution-RO1000 runs a 1:1 waste-to-product water ratio, conserving significantly more water than older or lower-efficiency RO designs. A liquid-filled inlet pressure gauge with marked safe zones takes the guesswork out of monitoring system health, while the garden hose connector and included 1:1/2:1 ratio restrictors make it straightforward to dial the system in for your specific setup.
