What does DWC mean in hydroponics?


How to get rid of roots in the substrate, which is being pushed by the weight of the plant?

Water and nutrients flow around the roots. They are pushed down to the roots by the weight of the plant. They are therefore "pushed into the substrate" by the weight of the plant, right?

What I need is help understanding why that happens. Is it because of gravity? No, there's still gravity inside the DWC. (Maybe there's "gravity" between the DWC and the roots? What does this term mean?)

Hydroponics is a system that uses air-filled transparent containers in which plants grow. The roots of the plant are allowed to grow into these containers, and in general, they don't touch the walls. Because there is no "soil" in hydroponics, water does not accumulate anywhere. When water comes into contact with the roots, it flows straight out.

The water needs to flow out of the containers. To do this, there needs to be a drainage system. When the roots are pushed down into the containers, the roots push against the drainage holes. Water pushes through the holes, moving through the drainage system and out of the containers. You can find drainage systems online, such as this one.

Deep Water Culture (DWC)

deep water culture for plants in containers. And if you want to grow flowers, you’ll need to find a water culture system that makes hydroponic plant feeding easy and accessible for your busy life.

Water Culture Systems

Water culture systems, also known as aquaponic systems, use the natural cycle of the water and the oxygen in the water to help the plants grow without outside fertilizers or pesticides. This system is a combination of aquaculture and hydroponics. You’ll need a shallow tank for the fish that acts as a natural ‘sink’ for the water so the nutrients in the fish can be easily taken up. The fish will use waste products to grow. The nutrients from the fish waste, along with oxygen from the fish, are absorbed by the plants.

This system also requires a greenhouse to keep the plants warm. The plants will absorb the oxygen in the water as well as the carbon dioxide from the air, so they grow more strongly than if you were only growing them in a pot. The fish provides the nutrients, while the plants supply the oxygen.

Advantages of Water Culture Systems

Water culture systems make it easy for you to grow your own vegetables. Aquaponics uses less water than other hydroponic systems, so if you live in a dry area, it’s an easy way to grow your own food. You can put it right under your kitchen sink. Because it uses no outside chemicals and pesticides, it’s easy to keep it in your home. The fish can live right in the house.

Water culture systems are also excellent for those who want to grow a specific type of plant. In the past, when you wanted to grow fruit and vegetables, you had to purchase them at a grocery store and grow them in pots. A water culture system is a great way to grow your own vegetables because you don’t need soil to grow vegetables, so you can grow any type of plant.

There are other benefits to aquaponics too. Aquaponics can make use of any available space. If you have a greenhouse, it will use any room that is under the roof. This makes it a great alternative for greenhouse enthusiasts who are looking for an out-of-doors solution to grow food. With some creative planning, you can build a large aquaponics system. You can even build a small system to make use of a back yard space.

Disadvantages of Water Culture Systems

Aquaponics isn’t suitable for all climates. If you live in a cold climate, you will need to buy a heating system. When you are harvesting the plants, you will need to use a large container, or have multiple smaller containers. Because you will be collecting all the plant’s food at once, you will need to use a container that is large enough to hold the amount you want to grow.

Aquaponics isn’t suitable for all climates. If you live in a hot area or if you just don’t have the space for an indoor system, consider installing your own.

The main reason that we aren’t all starting our aquaponics systems is because there are still a few little details that we haven’t yet covered. The biggest of those is how to safely and effectively clean the water of our fish. You could spend weeks researching this one, so let’s go over a few of the basics in this post!

Why Cleaning Your Fish Tank is Important

When you first start using your aquaponics system, you might be shocked to find out how filthy it gets. Fish water smells pretty terrible. In fact, most commercial fish tanks are not cleaned at all.

When you get your first batch of veggies, you’ll probably wonder how you could have gotten something so disgusting in a clean container. Even after you’ve used up all the fish food in the tank, you’ll still have to add more later, and more food is inevitably added to the tank when you do. You’ll eventually find that the tank has taken on an unmistakably nasty odor.

Why is this? In the first few months of operating your fish tank, you are not actually cleaning it.

As long as your fish are still alive, you won’t have to clean their tank or water. The food they eat is still broken down in their digestive tracts and can harmlessly leave the tank. However, as they start to die, bacteria begins to grow in the water.

If you don’t clean your tank, this bacteria will just accumulate and build up. The tank water will end up smelling awful because the tank’s walls begin to degrade. Eventually, the tank will begin to rust, and eventually you will have to fix it.

Luckily, cleaning your fish tank is pretty easy. Just follow these instructions to clean your fish tank and water efficiently.

How to Clean Your Fish Tank and Water

In order to keep your fish tank and water clean, you should follow these basic guidelines:

Clean and refill the water.

  • The most effective way to keep your tank and water clean is to make sure you refill the water when necessary. 
  • Keep your fish in a large and clean tank.
  • You should provide your fish with ample space to swim around in their tank. Ideally, your fish tank should be no more than 70 gallons.
  • If you wish, you can place a filter in the middle of the tank to purify the water.
  • However, you should never overfeed your fish or add any extra foods to their tank. This can cause bacterial buildup, leading to more water waste and even death.
  • In the beginning, you can use tap water. If you have access to a filter, you can use the tap water as-is.
  • Alternatively, you can fill the tank with a 1:10 mix of fresh tap water and fish tank water.
  • You can use this until you can get into the habit of re-filling your tank weekly.
