This item is supplied On Demand

The UV Lamp Kit 4 lpm Growmax incorporates a UV chamber that inactivates bacteria, viruses, and parasites as the ultraviolet beam passes through, preventing odors, strange tastes, and residues. It works as the final stage of the treatment train, upstream of the mixing tank or the irrigation system manifold. With a nominal capacity of 4 liters per minute, it is ideal for compact tanks, work tables, indoor grow cabinets, and small to medium-scale drip circuits.
UV disinfection reduces the biofilm that usually accumulates in pipes and drippers, extending the life of irrigation accessories and minimizing clogs.
For consistent performance, a sediment prefilter (and, if applicable, carbon) is recommended to improve water clarity and maximize UV exposure.
The kit integrates with standard fittings and allows for neat wall or rack mounting; operation is silent and maintenance focuses on periodic replacement of the UV lamp and keeping the quartz sleeve clean.
Overall, more stable water, reproducible recipes, and less incidence in lines, promoting uniform irrigation in substrate, coco, and hydroponics.
Available at Hydroponics Blanes, online grow shop with advice from a trusted Grow Shop and discreet shipping.
In controlled environments, water hygiene directly impacts root health and parameter consistency. The UV Lamp Kit 4 lpm Growmax provides a stable sanitary barrier that helps keep tanks cleaner, reduces sludge on walls, and prevents drippers from losing flow. Chemical-free disinfection preserves the profile of the nutrient solution and avoids interference with formulation.
It works in tandem with sediment filters (5–20 µm) and carbon filters, as well as with pH/EC meters, check valves, shut-off valves, quick connectors, and 3/8” or 1/4” tubing. Integrated after osmosis or deionization, the recommended train is: sediment → carbon → osmosis/deionization (optional) → UV Lamp Kit 4 lpm Growmax → mixing tank → distribution to irrigation accessories and drippers.
The investment is offset by fewer incidents due to clogs, less maintenance time, and greater stability of irrigation water. At Hydroponics Blanes you can find promotions, packs with filters, and discounts on consumables to optimize the mixing station budget.
Available at Hydroponics Blanes, trusted Grow Shop with technical advice, specialized catalog, and discreet shipping. The online grow shop allows you to add tanks, connectors, hoses, and meters to integrate the UV into any domestic or professional irrigation system.
