Is bacteria and biofilm building up in your reservoir?

Untreated water carries bacteria and microorganisms straight into your nutrient reservoir, feeding biofilm, blocking drippers and raising the risk of root-zone disease. The GrowMax UV Lamp Kit disinfects water as it flows through the UV chamber, keeping reservoirs and irrigation lines cleaner and improving overall water quality, which is particularly valuable for growers on well water or RO who need reliable microbiological protection.

How to Use

1. Install as the final stage of your water treatment, after any sediment, carbon or RO filters.
2. Mount the unit securely using the supplied wall clips.
3. Connect the included ¼" tubing and fittings to your water supply.
4. Keep flow at or below 4 litres per minute for effective sterilisation.
5. Switch on the UV unit whenever water is flowing through the system.
6. Replace the lamp every 12 months even if it still illuminates, and clean the quartz sleeve if mineral deposits form.
