About the book
Hydroculture is classified as a system to grow indoor decorative plant, it is passive system meaning no moving part, catered to make life easier for humans and plant. Hydroculture is a form of passive hydroponics and a way of growing plants without soil. Passive hydroponics systems often use an inert growing medium such as clay pebbles instead of soil. A hydroculture system is often made up of five simple parts – clay pebbles (or a similar inert growing medium), culture pots, water level indicator, pot liners, and fertiliser.
Hydroponics is growing plants in water actively, the water is always moving and never left or it will stagnate. It is focused on plant growth and is used for vegetables or any culture requiring production. There are many systems and way, they all stem from the same concept, how to suspend the plant, oxygenate the water and get the water to the roots. Hydroponic systems integrate the cultivation of plants without the use of soil, but with the use of an inert medium, such as gravel, sand, peat, vermiculite, pumice, perlite, coconut coir, sawdust, rice husks or other substrates, to which is added a nutritive solution that contains all the essential elements that a plant needs to achieve its normal growth and development. These days, there are hydroponic systems for the cultivation of vegetables in space stations to operate in places of very low gravity.
Hydrocultural and hydroponic systems are also being created in the roofing of buildings and some of them use photovoltaic panels to energize the pumping system, which in turn would pump the city's wastewater to irrigate the plants, which would benefit from sunlight.
The production of vegetables with hydrocultural and hydroponic systems has been increasing in the world and further research is needed to develop new hydrocultural and hydroponic systems to reduce the cost of energy and materials required for crop production, which is the scope of this book.
