Introduction of Controlled Environment Greenhouse
Introduction of Controlled-Environment Greenhouse (CE Greenhouse)
AFCD is now studying the development potentials of various types of Controlled-Environment Greenhouse.
Merits of using CE greenhouse
Application of CE greenhouse
CE greenhouse is suitable for production of high value premium vegetables and flowers such as sweet pepper, cherry tomato, white bitter cucumber, sweet melon, mini cucumber and lily cut flower. The use of CE greenhouse in organic cultivation is beneficial as the plants are more protected from pests, diseases and external pollution.
Structure and facilities of CE greenhouse
The framework of CE greenhouse is usually built with rust-proof iron bars and sealed with materials such as polyethylene film or polycarbonate sheet. A CE greenhouse is usually equipped with automatic environmental control system and irrigation system.
CE Greenhouse construction and cost estimation
To construct a greenhouse, applications should be made to the Lands Department other than getting the landlord's written consent.
The cost of a CE greenhouse depends on the size of the building, the quality grade of the building materials and also the facilities installed. A CE Greenhouse of 200 m2 equipped with a water wall, cooling fans and a drip irrigation system is estimated to be over HK$100,000.
