The WaterFarm Circulating Upgrade Kit contains everything needed to reconfigure your system to add nutrient circulation capability.
What will this do for you? Promote plant growth consistancy and improved health. The added circulation keeps the nutrients balanced throughout your WaterFarm 8-Pack system. In turn you'll see more consistant pH levels and the increased oxygenation that plants thrive on.
The constant water movement also prevents sediment buildup for healthier plant roots.
