DWC solves the oxygen problem by using an air pump, or falling water so that there will be air bubbles rising up from the nutrient solution, and the dissolved water in the reservoir. In DWC, plants absorb sufficient oxygen while also able to take up the nutrients and water around it all days.

What grows well in DWC?

The best crops for deep water culture are small and lightweight. Lettuce, for example, is a popular DWC crop and the perfect size to fit on rafts. Larger crops like tomatoes grow top-heavy. Without the root anchoring provided by a dense media, top-heavy plants can fall over or break at the stems.
