In hydroponic systems from DWC (Deep Water Culture or Direct Water Culture), plants grow suspended in an oxygen-rich nutrient and water solution. As the plants consume the nutrient solution and water, the solution is pulled out of it for all connected buckets of plants. Attempting to manually drain your buckets can injure your plant and destabilize the nutrient’s pH. This thwarts the purpose of using 5 gallon buckets for hydroponics in the first place.
how much water do you put in a 5 gallon DWC bucket
For convenience, you can expect to fill just a 5 gallon DWC bucket with 2.5 to 3 gallons of water. In DWC, plants absorb enough oxygen while being able to absorb the nutrients and water around them throughout the day. This 5 gallon hydroponic bucket is extremely easy to make. If you have an aquarium, you probably already have a lot of the supplies you need in your house. Moving the water not only increases the size of the reservoir volume, but also helps maintain nutrient density, water pH, and oxygen supply together.
