A few of the most commonly known DWC methods include:. Traditional DWC systems work both indoors and outdoors. Classic DWCs are among the most basic forms of hydroponics and take little time to master. The section above explains how the traditional DWC systems work in detail. The system works somewhat like a hybrid between a classic DWC system and the flood-and-drain hydroponic technique. Instead, water and nutrients are recirculated from each reservoir to the next.

Eventually, the water returns to the main reservoir and begins flowing through the entire system again. RDWC systems typically consist of several bucket-like reservoirs designed for growing a single plant. Each container is connected to the next one in the series via a hose. Because the traditional DWC has its own downsides and cannot scale big, the recirculating deep water culture was created. This type of DWC requires a bit more time to set up, extra air stones, and of course, a bit more cash as well.

A more primitive take on the traditional DWC technique is the Kratky method. To properly aerate root systems using the Kratky system, there must be a large enough space between the root system and the top of the water.

This gap between plant and reservoir allows the plant to breathe in air in a fashion similar to how soil-grown plants do. One of the biggest advantages of the Kratky method is that no electricity is required. However, it can be a bit tricky to get the hang of. The DWC method known as bubbleponics is another interesting and successful hydroponic technique.

It is quite similar to the standard DWV setup, except that it involves the addition of a water pump submerged within the reservoir. The water pump sends water up and into the tops of your netted pots, soaking the seedlings and providing them with water and nutrients.

This technique helps to stimulate growth and speeds up root development. All things considered, bubbleponics is more of a technique than a complete growing method because it is often not used beyond the germination phase of growing crops. That said, if used long-term, it is considered a top-feeding DWC system. For large business DWC systems, it usually makes more sense to use nutrient and pH doses simply. This helps maintain optimal conditions in your water culture system and protect against human error.

The most appropriate plants to develop with deep culture systems do not need to blossom, including many lettuces and many different herbs. These crops grow super fast and healthy.

Besides that, you may also grow tomatoes, peppers, as well as bigger fruits like squash even though they take somewhat more effort. These are extremely simple to set up, inexpensive while still producing excellent yields that you would enjoy. Start small, you begin. Deep water culture system is a method of growing plants in aerated water. Bubbleponics is the closest version to the traditional system of setting up a deep water culture farm.

Here, the oxygen is supplied to the water with the help of an airstone and air pump as well. The only major departure comes from the use of a water pump inside the water tank in order to effectively move all the bits of nutrition to the top of the container. Once the nutrition moves to the top of the tank and hits the roots of the plants, it falls back down and again, and this cycle continues infinitely.

This method of DWC is especially popularly used when the plants are in the nascent stage of their development. When the roots are their shortest, they have trouble accessing all the nutrients in the water. Thanks to bubbleponics, the nutrients are continually circulated in the water and ensure that they access the roots during their vital developmental phase. Using bubbleponics can be great for plants as they help to speed up the growth of the seedling and increase the pace of the germination process as well.

In fact, this is a very passive system that does not use any form of electricity whatsoever. This allows a section of the roots to be submerged underwater, while another section is left open to the air.

There are many ways in which you can set up a deep water culture system to match your needs as a farmer. The easiest method of securing the required equipment to start a farm would be to pick up a fully system kit.

These are available online and for a wide range of budget options. All of these tools are easily available at most quality hydroponic or gardening stores. When picking out a water tank, make sure to get a model that isn't coated with a light color.

You want to try and limit the amount of light passing through the tank, so ideally you should seek out tanks that have a darker tint to them. After selecting the tank, it needs to be filled with the growing solution selected for the farm. The solution needs to cover the tank entirely and reach up till the base of the mesh pots. After this, it is crucial to keep a check on the pH levels in the water.

The ideal range is between 5. Next, the oxygen supply needs to be regulated. This can be done by connecting the pump to the airline, and then connecting the airline to the airstone. Once these connections have been made, the airstone can be placed at the bottom of the reservoir.

You can now begin to place the plants in the pots and allow the roots to hit the water. Turning the pump on at this stage will kickstart the whole system. The traditional methods of farming are falling to the wayside as novel methods emerge to match the demands of the market. Hydroponic farming is indeed a boon to the modern world.

Its many subsections such as DWC offer farmers with plenty of alternatives to grow healthy and hearty crops across the year. DWC is a relatively new form of hydroponic farming, but it is picking up steam quickly because of the ease with which it is possible to set up this system.

Information regarding the merits of this system needs to be spread across the farming community to ensure that everyone has access to this form of farming. Solving the global hunger crisis will only be a few short steps away from that point. Sign up here for our Food Systems Forum from Jul! Agriculture Agriculture.
