How Does DWC Work?

Your plants sit directly into the water that has been added with nutrients for them to drink up as needed.

The oxygenated water will provide everything your plant needs, so there is no need for soil. Instead, you will be adding mediums like perlite, Rockwool cubes, or coco fiber which act as both excellent growing materials and anchor the plant in place.

The air stones oxygenate and agitate the water, which helps to keep your plants healthy! The air stones also help to prevent any build-up of salt on your growing mediums.

Further, the roots of the plants grow through holes in mesh pots that you place into a floating raft made out of Styrofoam or plastic. This allows oxygen from outside to get inside to breathe properly while also getting nutrients and minerals directly from the nutrient solution below them by using capillary action.

The water level is not the same all around your plants — instead, it’s lower where they are growing!

Advantages and Disadvantages of Using Deep Water Culture System


Deep Water Culture type hydroponic system has the following benefits over other types of systems:

  1. It is a very simple system to set up and use. You can use any type or size of the container as long as it has a top that will fit tightly.
  2. You can set up this system indoors or outdoors.
  3. It is one of the most productive types of hydroponic systems.
  4. The plants are suspended in nutrient-rich water, so they get more light and oxygen than in other types of systems.
  5. There is less chance of disease and pests affecting the plants.
  6. It is effortless to maintain, and it requires very little time and attention from you!
  7. You don’t need a lot of space either — even if you live in an apartment, you can still use a Deep Water Culture Hydroponic System!


The main disadvantages of the deep water culture system are:

  1. The nutrient solution is virtually still, leading to bacterial growth, algae growth, and fungi and molds. The nutrient-rich water can cause problems with the pH level and requires regular monitoring.
  2. A simple air pump does not provide good aeration, leaving some plants without adequate oxygen. Therefore, buy an air pump fit for the system.
  3. The best place for the air stone is in the middle of the tank, but plants around the edges will not get their fair share. If we add airstones in corners, it will also help to avoid the problem.
  4. It isn’t easy to clean the tank or container thoroughly when it is not used.
  5. Some plants cannot stand having their roots “wet” all the time and may rot if this system is used.

How Many Plants Can You Grow with DWC?

You can use this method of growing in small spaces! If you are only planning on growing one plant at a time, then a five-gallon bucket will work best.

If you need more room for multiple plants, try using trash cans instead! The space you will be using depends on what type of product or herbs you’re trying to grow.

Some Tips for Doing Deep Water Culture Hydroponics

  • Do your research — figure out what plants you want to grow and learn their water and nutrient needs.
  • Get a powerful pump — the bigger your deep water culture system gets, the more powerful your pump will need to be.
  • Use the correct nutrients for your plants and follow the directions carefully.
  • Mix up your nutrient solution and adjust it as needed.
  • Clean out old solutions regularly and keep an eye on pH levels and nutrient levels.
  • Ensure there’s enough oxygen in the water and that the growing medium doesn’t get too soggy.
  • Keep an eye on water levels and top off when necessary.
  • Establish a routine for checking on your deep water culture system and be prepared to make changes as needed.
