There are different ways that can be used to grow plans without any soil. Most of these options are advanced by people who use special mediums other than soil to grow different plants and flowers. The main difference is that new mediums require less water because they use different substances other than growing materials and water. For example, hydroponics is one of these innovative methods that allow people to grow many plants in special liquid solutions without using soil.
Another popular method is hydroculture and it’s quite similar to the first one, while being quite different in its fundamental level. What is it all about? Most people are familiar with hydroponics because this term involves growing plants in special liquid solutions that are becoming more and more popular, especially when growing such vegetables as tomatoes and lettuce. When it comes to hydroculture, it’s quite similar to this method, but the main difference is that inorganic solid growing mediums are used instead of liquid solutions.
Inert growing mediums are rock-based and they are often called as expanded clay aggregates, so hydroculture is considered as passive hydroponics, and this means that plants are grown without any soil or peat moss. Why to use clay aggregates? They are also called LECA and they consist of the small clay pieces. People need to heat small clay pellets to high temperature levels in special rotating kilns. This heat forces clay particles to expand, and this process is quite similar to popcorn popping. When clay pieces expand, they lose density and have many air pockets inside, so final products are aggregates that are marble-sized. Consumers can find other versions of LECA and they have different looks, but everything depends on clay sources and manufacturing processes, but they all become efficient growing mediums.
Why are they perfect growing mediums? LECA comes with a few desirable growing properties, including being very porous, and this is what provides them with enough oxygen and air for the roots of plants. The lack of oxygen is one of the main causes of plant loss, especially when growing interior plants, while their healthy roots are less prone to rotting and different diseases. They also have capillary properties that allow dry LECA to absorb enough water and provide it to growing plants. Finally, they don’t decay or compact over time.
