GrowMax Water Garden Grow Water Filter 480 L/h

The GrowMax Water Garden Grow is a powerful, two-stage water filter specially designed for use in horticulture, greenhouses, urban farming, and indoor growing. With a flow rate of up to 480 L/h, it reliably supplies your plants with purified water – completely without electricity consumption .

Easy connection – ready to use

Thanks to the included 3/4" garden hose adapter, the Garden Grow can be connected to any common water source in just a few minutes—e.g., in the garden, at the outside faucet, or in the house. The filter cartridges are housed in a robust housing with a quick-change thread for particularly easy maintenance.

Why filtered water?

Tap water often contains chlorine, sediment, pesticides, and heavy metals , which not only disrupt soil life but also hinder nutrient absorption . Garden Grow removes up to 99% of these substances , resulting in healthier plants, stronger roots, and better harvest quality —especially when using organic fertilizers or compost tea .

Filter technology & replacement intervals

The system consists of two filter stages:

1. 5-micron sediment filter – removes sand, rust, dirt & deposits
2. Granulated activated carbon (GAC) filter – removes chlorine, pesticides, VOCs and unpleasant odors

To ensure consistent water quality , the filter cartridges should be replaced every 4–6 months or after approximately 11,000 liters of use, depending on the water quality at your location. Replacement filter sets are available separately and can be replaced quickly and without tools.
