10 GROWMAX Deionization Kit designed to obtain ultra pure water 000 ppm as a final stage after reverse osmosis. Includes blue 10” housing, DI resin cartridge, metal bracket and quick connections to integrate into indoor cultivation mixing stations.

The 10 GROWMAX Deionization Kit adds a final polish to osmosis water, bringing the TDS reading towards 000 ppm for more stable and repeatable nutrient recipes. The blue 10” housing contains a deionization cartridge that captures residual ions (calcium, magnesium, sodium, bicarbonates, etc.), refining the base water before mixing fertilizers.
The set includes a white metal bracket for wall or rack mounting, 3/8” to 1/4” adapters (2 units) for compatibility with standard osmosis lines, 3/8” white tubing for clean routing, 3/8” ball valve for quick in-line maintenance, and a wrench to facilitate filter housing service. In indoor grow rooms and tents, very low-salt base water simplifies EC/pH control, reduces precipitates, and improves nutrient availability.
That’s why this DI module fits into stations with a tank, manifold, and drip or recirculation irrigation system, providing consistency when watering indoor crops.
Recommended for those seeking fine recipes in coco, hydroponics, or light substrate, and wanting to minimize batch-to-batch variations.
Available at Hydroponics Blanes, online grow shop with advice from a trusted Grow Shop and discreet shipping, along with other compatible irrigation accessories.
Starting water with extremely low TDS allows you to build the nutrient solution from scratch, precisely adjusting calcium-magnesium, base A/B, and additives without local salt carryover. This results in EC stability, clearer fertilization curves, and less risk of lockout or buildup in substrates and lines. The 10 GROWMAX Deionization Kit works as a post-stage to the osmosis unit, ensuring a final polish before the working tank.
Works outstandingly with pH and EC meters to verify polishing, pre-filters for sediment and carbon (part of the osmosis unit), pressure gauges to control pressure, shut-off valves 1/4”–3/8”, quick connectors, and transfer hoses. In complete stations, it combines with tanks with taps, recirculation pumps, manifolds, and drippers, ensuring each line receives very low-salt water before mixing. Other irrigation accessories such as check valves and in-line filters help preserve flow and cleanliness in the circuit.
Investment focused on water quality and savings on incidents: fewer precipitates, cleaner lines, and repeatable recipes. At Hydroponics Blanes you’ll find packs with replacement DI cartridges and accessories to optimize costs in treatment stations and irrigation systems.
Available at Hydroponics Blanes, trusted Grow Shop with discreet shipping and specialized advice. This online grow shop allows you to complete your order with osmosis units, pressure gauges, hoses, connectors, and meters to integrate the DI module into any setup.
