The roots of the plants are continuously submerged in a nutrient and oxygen-rich water solution growing healthier plants with greater yields.

  • RDWC systems grow healthier plants with greater yield potential by providing plants with continuous access to water, oxygen, and nutrients
  • Oxygenated water enables the plant roots to absorb nutrients more efficiently, increasing plant growth rate substantially
  • Nutrients are evenly distributed to each connected grow site and maintain a consistent level across all grow sites
  • The constant flow of water helps prevent algae, bacteria, and fungi from growing, while also keeping plant roots clean and healthy
  • RDWC systems are relatively low maintenance; Check nutrient solution often and top up the as needed through the central reservoir; change the solution in the reservoir every one or two weeks
