Introduction to Hydroponics
Hydroponic systems can be set up in various locations without the need for soil. There are different types of systems that utilize water and nutrient solutions to feed plants. Growing indoors provides protection and requires lighting, but not sunlight.
Hydroponics in Greenhouses
The fusion of hydroponics with greenhouses offers benefits such as increased yields and year-round cultivation. In a hydroponic greenhouse, plants are raised in nutrient solutions instead of soil, with sensors automatically supplying nutrients.
Major Requirements for Hydroponics
Hydroponics requires water, nutrients, light, and a system for circulating solutions. To start hydroponics, rinse soil from plant roots, control temperature, lighting, and grow period. Utilizing sunlight can help save on lighting costs and cooling nutrient water can improve performance.
Vertical Hydroponic Systems
Vertical hydroponic systems maximize space utilization, reduce water usage, chemical runoff, and land requirements compared to conventional farming. The simplest home hydroponic system is Deep Water Culture, where plant roots absorb water and nutrients from a tank below.
