Growmax Water Filters

Growmax water filters remove chlorine, salts, and contaminants from tap water, giving you cleaner, more stable water for hydroponics and indoor growing. Ideal for improving nutrient accuracy, reducing EC, and protecting ir

Why Use a Growmax Filter?

Water quality directly affects nutrient uptake, pH stability, and overall plant health. Many UK water supplies contain:

  • High bicarbonates

  • Elevated EC levels

  • Chlorine or chloramine

  • Dissolved salts and heavy metals

Filtering your water helps you start with a clean baseline — especially important in coco, DWC, NFT, and recirculating hydro systems.

Key Benefits

  • Lower starting EC

  • Improved nutrient control

  • Reduced pH drift

  • Protects pumps and drippers

  • Better consistency in automated systems

Which One Do You Need?

  • High EC (above 0.4–0.5)? → RO system

  • Hard water? → RO system

  • Chlorine issues only? → Carbon filter

  • Organic soil grow? → Eco Grow

Not sure? Test your water EC first or contact us for advice.

Clean Water = Better Control

If you're serious about dialling in your feeding schedule, filtered water makes everything easier — from mixing nutrients to maintaining stable reservoirs.

Growmax filters give you a reliable starting point for healthier, more consistent growth.
