Hydroponics is a method that preserves water and soil, it is very productive. Hydroponics is an advanced technology but requires only basic skills to start farming. It is important to control the temperature of the air and roots, including factors such as water, light, plant nutrition, and extreme climates. For this reason, hydroponics systems often have to work in temperature-controlled environments such as greenhouses.

Hydroponics is a form of soilless cultivation in which plants are grown in nutrient solutions, with or without the use of an artificial medium. It is very important to pay special attention to the greenhouse conditions; otherwise, hydroponics will no longer be profitable for you. In liquid hydroponic systems, there is no support for plant roots. This is also called a solution culture; the three main types of solution culture are solution culture, continuous flow of solution culture and geoponics.

In the first, the plants are grown in containers with a hydroponic nutrient solution. These are usually domestic applications where hydroponic systems work in glass jars, plastic buckets, tubs, and tanks. The solution is sometimes slightly aerated, but may also be non-aerated, in which case the level of the solution is low enough that part of the roots has access to the regular supply of oxygen. The nutrient solution is replaced according to a predetermined schedule, mainly once a week. The culture of the continuous flow solution is orchestrated differently, with the hydroponic nutrient solution flowing along with the roots.

This book covers the following topics:

• What is hydroponics gardening
• Hydroponics vs soil gardening
• How it works
• Different types of hydroponics systems
• How to start your hydroponics garden
• Tips and tricks to growing healthy herbs, vegetables and fruits
• Possible issues of a hydroponic garden
• Best plants for hydroponics

...And much more

A popular version of this culture is the technique of the food film; a very shallow stream of water with all the dissolved nutrients needed for plant growth flows along with the roots of the plants. The hydroponic nutrient solution moves through the lower half of the roots and forms a tight root mat, while the upper parts of the roots are exposed to air and receive a good supply of oxygen. However, aggregate hydroponics systems have natural or artificial solid support.

Can hydroponics systems also be open? When the nutrient solution is delivered to the plant roots and not reused or closed, where the surplus solution can be collected, supplemented, and recycled. Each crop has very specific requirements and, as with any other farming method, hydroponics must pay attention to the unique needs of each crop.

Hydroponic systems are evolving rapidly today, and yields are rising and reaching heights we had never expected. Hydroponics is possible in places where this is not the case with natural agriculture, including deserts and space stations. People who live in densely populated places can grow their fresh vegetables in roof gardens or windows using hydroponics. Plants that are grown in hydroponics also grow faster and are relatively free from soil diseases.
