Film can provide shade for heat-sensitive crops. Black-white film reflects excess radiation while allowing some light transmission. Apply mud on film to create dappled shadows; reapply after rain washes it off. Use air convection for cooling by opening lower and upper vents simultaneously for airflow. Scientific watering with light, frequent applications increases humidity and cools through evaporation. Film covering prevents soil compaction from rain impact. Rain flows along film into drainage ditches, preventing waterlogging.
