What Is a Greenhouse?
A metallic greenhouse in Kenya is a protective structure designed to create a controlled environment for growing crops. It allows for regulation of temperature, humidity, and light, shielding plants from pests, excessive rainfall, drought, and extreme sun. In Kenya, metallic greenhouses in Kenya are used for:
- Horticultural farming (e.g., tomatoes, capsicum, cucumber, lettuce)
- Seedling propagation (nursery stage)
- Azolla farming (used in livestock and fish feed)
- Fish farming (aquaponics systems under shade)
- Vertical farming and hydroponics
With a variety of greenhouse sizes in Kenya, these structures cater to smallholder farmers as well as large-scale investors.
