Deep Water Culture (DWC) is a hydroponic method of growing where a plant's roots are suspended in a bath of water made up of air bubbles and nutrients.

Here are the benefits of Deep Water Culture growing:


  • Low maintenance.
  • Faster growing time compared to soil-grown plants.
  • No soil, so no bugs.


There are three important parts that a Grobo uses:


  1. Oxygen: The air stone and air pump in the Grobo keep the water well oxygenated so the plant doesn't drown.
  2. Water: Your Grobo requires weekly draining and filling to ensure the water in the DWC tank stays fresh.
  3. Nutrients: Grobo's automatic dosing ensures that your plant has all the micro and macronutrients to grow and thrive.
