Answer 1

Advantages of Protected Cultivation

• Enables year-round production of flowers irrespective of climate.
• Protects plants from adverse weather such as frost, heavy rain, and strong winds.
• Reduces pest and disease incidence by controlling environmental factors.
• Enhances flower quality and yield due to controlled conditions.
• Efficient use of water and nutrients.

Management of High Temperature

• Use of shade nets or whitewash on greenhouse roofs to reduce sunlight intensity.
• Ventilation through side vents and roof openings to allow heat escape.
• Evaporative cooling using foggers or misting systems.
• Use of cooling pads and fans in large greenhouses.
• Proper orientation and design to optimize air flow.
