Deep Water Culture System Hydroponic
Deep Water Culture systems are also commonly known as DWCs. Now, there is a misconception that a DWC is an altogether different type of hydroponic setup. This, however, is not true. It is simply an adaptation of an installation known as a water culture system.
So, what is a DWC? A DWC refers to a water culture system where the water depth is greater than a typical system. In most instances, a basic hydroponic setup has a depth that is between eight and ten inches. A Deep Water Culture system is one that consists of a greater depth than that.
The Differences Between a DWC and Traditional System
The only real difference between a DWC and a traditional system is the depth. In every other facet, these two systems are the same. This is because they function in the same way – the plant roots are submerged in a nutrient solution so that they can receive the proper nourishment. In order for the system to be efficient, the water needs to be properly aerated.
When Is a DWC System Used?
If the two systems are virtually identical, this begs the question when does a grower require a DWC instead of a more shallow water culture system? A DWC is typically utilized when attempting to grow larger plants. These plants have longer root systems that cannot be accommodated in traditional reservoirs. Furthermore, the larger plants also require a greater nutrient and water uptake. This can only be managed with a greater water depth. Sometimes, a DWC is required when the container is quite deep and the nutrient solution needs to be able to reach the main root.
There aren’t many plants that actually require such a great water depth. Most smaller plants are able to flourish in depths as little as six inches.
The Particulars of a DWC System
A DWC system, like any other water culture system, must be managed well. This largely refers to the fact that the water needs to be well oxygenated so that the root system will always have an adequate amount of oxygen, even as the plant grows and gets larger.
The other thing that is relevant to such a system is water volume. The depth (or height) of the water is quite different to that of the volume. While the volume remains the same, the depth of the water changes according to the height and the width of the container in which it is placed.
The volume is important because the plants, especially the bigger ones, need to take in a certain amount of water and nutrients to be able to grow. As a rule of thumb, if you are growing large plants, you should provide each plant with at least two and a half gallons. With medium sized plants, this can be reduced to either one or one and a half gallons.
This is what you need to understand about Deep Water Culture systems. In every way – except for one – these water systems are the same as other basic setups. The main difference here is the depth of the water.
