Kit UV Lamp 22 LPM Growmax sterilizes water without chemicals using UV radiation in a stainless steel housing. It deactivates viruses, bacteria, and parasites, delivering clear water ready for nutrient mixes in indoor cultivation and irrigation system tanks.
This product is supplied On Demand

The Growmax UV Lamp Kit 22 LPM is designed as the final stage of treatment, providing a hygienic barrier that preserves water quality before the working tank or distribution to drippers.
The stainless steel chamber reflects UV light to maximize exposure and contact, achieving effective disinfection without the addition of chlorine or generation of waste.
Ultraviolet technology acts on the DNA of microorganisms and offers an inactivation rate of 99.99% against common pathogens. To ensure performance, a sediment filter is recommended beforehand (and optionally carbon) to improve water clarity.
Installation can be done horizontally —the preferred option— or vertically, feeding from the bottom and exiting from the top to ensure proper purging.
The kit includes a transformer, 2 3/8” fittings, 2 fixing clips, and 3 m of 3/8” blue tubing for quick and tidy connections. In mixing rooms, cabinets, or technical rooms, the UV module keeps tanks clean for longer, reduces biofilm in lines, and helps water indoor crops with a higher sanitary standard.
Compatible with filtration and Growmax reverse osmosis, as well as with custom stations available at Hydroponics Blanes online grow shop with discreet shipping and a wide range of irrigation accessories.
In indoor growing installations, water hygiene reduces blockages and minimizes root pathogen risks. With a capacity of 22 LPM (liters per minute), this UV lamp matches typical flows for filling tanks and servicing drip circuits, recirculation, or drainage to waste. The result is cleaner lines, tanks with less slime formation, and greater parameter stability in the irrigation system.
It is complemented with sediment pre-filters (5–20 µm), carbon filters, pressure gauges, non-return valves, 3/8” shut-off valves, tubing and quick connectors, as well as pH and EC meters for recipe control. In combinations with osmosis and tanks with a tap, the train is: sediments → carbon → osmosis (optional) → Growmax UV Lamp Kit 22 LPM → mixing tank → distribution to irrigation accessories and drippers.
The cost is offset by lower maintenance of lines, fewer blockages, and more stable water. At Hydroponics Blanes you will find offers and packs together with filters, tanks, and irrigation accessories that optimize the mixing station budget.
Available at Hydroponics Blanes, trusted Grow Shop with specialized advice and discreet shipping. In this online grow shop you can add pre-filters, osmosis, pipes, connectors, and valves to integrate the UV into any irrigation system.
Includes: transformer | 2 3/8” connections | 2 clips | 3 m of 3/8” blue tube. Recommended as the last stage of the treatment train, preferably with horizontal installation.
For those seeking disinfected water without residues, the Growmax UV Lamp Kit 22 LPM offers a decisive step: fast disinfection, easy integration, and tangible improvement in circuit hygiene.
Ideal as reinforcement in mixing and distribution tanks to water indoor crops reliably, available at Hydroponics Blanes with the convenience of an online grow shop and the support of a trusted Grow Shop.
