GrowMax Water Power Grow 500 reverse osmosis system

The GrowMax Water Power Grow 500 is a powerful reverse osmosis system specifically designed for use in hydroponic systems and indoor gardens. With a capacity of up to 500 liters of pure osmosis water per day, it's the ideal choice for providing your plants with the best possible water quality.

Pure water for healthy plants

The Power Grow 500 removes up to 95% of salts and heavy metals, as well as many other contaminants such as chloramines, nitrates, nitrites, chlorine, pesticides, herbicides, and volatile organic compounds (e.g., benzene, tolerol, oil, and detergents). The purified water has a pH of approximately 6.5 and an extremely low EC of 0.1, allowing for precise nutrient control.

Optimal nutrient supply for your plants

Regular tap water often has an EC value between 0.8 and 1. However, plants can only absorb a limited amount of dissolved substances. Thanks to the low EC value of reverse osmosis water, your plants benefit from greater availability and optimal absorption of nutrients .

Easy installation and reliable performance

Installing the GrowMax Water Power Grow 500 is quick and easy. To maximize the system's performance, the following conditions should be met:

• Water temperature: 25°C
• Inlet water pressure: 3 to 5 kg/cm² (corresponds to normal house connections)
• Water quality: 550 ppm or less

To ensure consistently high water quality, the filters should be replaced every 4 to 6 months. This ensures the system remains efficient and reliable over the long term.

Perfect for organic farming

Osmosis water is ideal for organic farmers because it protects the beneficial microorganisms in the soil and supports pH stabilization . This allows your plants to benefit from a 100% nutrient supply—ideal for sustainable cultivation with Living Soil and BioTabs.

With the GrowMax Water Power Grow 500 you ensure that your plants receive only the purest water – for strong growth and healthy yields.
