SYNOPSIS

MARDI has carried out research on the development of a fully controlled environment greenhouse for the cultivation of temperate crops in lowland tropics.  The objective is to generate effective and suitable environment for growing temperate crops under tropical climate and to undertake studies to fulfill the crop requirements. The innovation comprised of design techniques of a controlled environment greenhouse (CEGH) to generate effective environmental conditions that satisfies the temperate crop requirements.  Specific environmental parameters are set-up, controlled within the comfort zones and stabilized which subjected to external environment variation. The environment is generated by mechanized environmental control system (ECS) including tailored design air-condition, roof-top ventilator, humidifier, CO2 enrichment, photo-periodic lighting and fertigation. The lower limit temperature is induced by air cooling system, distributed through conduits. The upper limit temperature is controlled by the automatic ventilation fans fixed on-top of the double layer roofs, while RH is controlled by humidifier and all are automatically controlled by a computer. The designed of control mechanism is based on the principle of “Stratified air-space” in a controlled volume. This control plane moves up/down as influenced by the external environment.  The temperate crops selected were those with high commercial value including broccoli, Brussels sprouts, cauliflower, iceberg lettuce, coral sallots, chrysanthemum and strawberry.
