Tropical greenhouse misty

Tropical greenhouse with misting system maintains high humidity for exotic and ornamental plant cultivation.

About this subject

A tropical greenhouse is an enclosed structure designed to recreate the climate of tropical regions, with temperatures between 25°C and 35°C and relative humidity above 70%. They are essential for growing plants that require constant heat and moisture, such as orchids, ferns, and bromeliads. Unlike standard greenhouses, tropical ones rely on misting systems to raise humidity, along with fans and shade cloths to control temperature.

Misting not only maintains humidity but also lowers leaf temperature and helps prevent pests, since many pests do not thrive in very humid environments. Modern systems use sensors to automatically adjust spray frequency, saving water. In Brazil, tropical greenhouses are common in drier regions like the Cerrado, where flower and native seedling producers use this technology to enable cultivation.

Popular plants include Phalaenopsis and Cattleya orchids, which require high humidity to bloom. Ornamental ferns like the Boston fern (Nephrolepis exaltata) and bromeliads of the genus Aechmea are also grown. These greenhouses allow year-round production regardless of outside weather, making them vital for floriculture and botanical research.

Globally, tropical greenhouses are used in botanical gardens and research centers for conservation of endangered species. In England, the Royal Botanic Gardens, Kew, features a famous Victorian tropical greenhouse. In Brazil, the Rio de Janeiro Botanical Garden maintains tropical greenhouses for exhibition and study of Amazon and Atlantic Forest flora.

Frequently Asked Questions

What is a tropical greenhouse?

It is an enclosed structure that recreates the hot and humid climate of tropical regions, using heating, misting, and light control systems to grow plants that depend on such conditions.

Why is misting important in tropical greenhouses?

Misting increases relative humidity, essential for tropical plants, and also lowers temperature and prevents water stress. It helps control pests, as many do not thrive in high humidity.

Which plants are most common in tropical greenhouses?

Orchids (such as Phalaenopsis and Cattleya), ornamental ferns, bromeliads, anthuriums, and some palms are frequently grown in tropical greenhouses.
