Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Concept
Evaporative cooling systems in greenhouses use wet pads and fans to lower temperatures.
Step 2: Meaning
The pad material must hold water efficiently and allow air to pass through with minimal resistance while maximizing surface area.
Step 3: Analysis
While older systems used straw or wood shavings (excelsior), modern industrial systems predominantly use cross-fluted cellulose paper that is specially treated to prevent rot.
Step 4: Conclusion
Cross fluted cellulose is the modern standard.
Final Answer: (C)
