How does hydroponic farming work? hydroponics – how it works?
A hydroponic farm would consist of many white plastic boxes which are filled with growing medium. These tubes can be used to distribute nutrients from a reservoir in the centre of each box to the growing medium. The type of growing medium you use will depend on what type of crop you are growing, as well as the intensity of your climate. It is also possible to grow crops in enclosed shipping containers – an alternative that is less expensive to set up.
Why is hydroponic farming the future of farming?
Hydroponic farming has long been used to grow plants that are not suitable to grow in soil. Because of this, hydroponic farmers are more energy efficient, use fewer chemicals, and are not affected by the vagaries of the weather. They also have a wide range of growing options. You can use the same equipment to grow tomatoes as you do for lettuces, and you can grow carrots in the same way you grow parsnips.
But as the industry expands, the cost of growing vegetables and herbs indoors has come down, which means that hydroponic farming can compete with outdoor farms for some crops, such as cucumbers, and in some cases, even compete with rooftop farms, too.
What is the hydroponics method of agriculture?
Hydroponic farming involves growing plants in small containers and using nutrient solutions to feed the plants. The method is one of the most effective ways of growing plants in a controlled environment because plants can be grown without soil. A typical system is based on plastic tubes which are filled with growing medium, and which are rotated by the plants’ roots. These tubes can be used to distribute nutrients from a reservoir in the centre of each box to the growing medium.
Why are hydroponic methods growing?
Hydroponic systems allow you to grow crops without soil. The method is particularly good for plants that would normally need a great deal of care, such as plants for salad or herbs. As the industry expands, the cost of growing vegetables and herbs indoors has come down, which means that hydroponic farming can compete with outdoor farms for some crops, such as cucumbers, and in some cases, even compete with rooftop farms, too. Many hydroponic farming systems can be controlled by remote systems, meaning you can set up your own farm from your living room.
Because hydroponic farming requires less natural materials than land-based farming methods, some people are saying it is not a sustainable way of growing food. However, an increasing amount of research is being devoted to the use of hydroponics to help regenerate degraded soils and to reduce carbon emissions.
What are the benefits of farming hydroponics?
Although more research is needed, the following benefits have been recorded as being associated with hydroponic farming:
- more efficient use of water than conventional agriculture
- fewer pesticides used to control pests and diseases
- better performance of fertilisers and anti-slavery agents
- less labour costs
- improved stability of supplies of fresh produce
- a higher supply of natural foods in underserved and remote areas
- the production of healthier crops that are better suited for specific diets
- improved quality of the crops
- improved soil quality
hydroponic gardening is also widely recognised as a cheaper and more environmentally friendly form of farming than conventional. Hydroponics enable crops to be grown without the use of fossil fuels. A large area of land can be cultivated using less land and without using fertilisers, which the soil can remove naturally. Hydroponic gardening also avoids nutrient deficiencies, which can occur in conventional gardening due to high usage of fertilisers, fungicides and pesticides.
