Answer 1

Benefits of Controlled Environment Agriculture

• Facilitates continuous flower production regardless of external weather conditions.
• Safeguards crops against harsh elements like frost, excessive rainfall, and strong winds.
• Mitigates pest and disease outbreaks through environmental regulation.
• Improves flower quality and output by maintaining optimal conditions.
• Optimizes the utilization of water and essential nutrients.

Strategies for Managing Excessive Heat

• Application of shading materials or reflective coatings on greenhouse exteriors to diminish solar radiation.
• Employing ventilation systems via openings at the sides and top to expel accumulated heat.
• Implementing evaporative cooling techniques such as fogging or misting.
• Utilizing cooling panels and air circulation fans in extensive greenhouse facilities.
• Strategic positioning and structural design to maximize air movement.
