RH (Relative Humidity)
Relative Humidity (RH) is a key measurement in indoor farming that shows how much moisture is in the air compared to how much it could hold at that temperature. It's like a percentage score of air moisture. In vertical farming and greenhouse operations, keeping the right RH level is crucial because it affects how well plants grow, prevents diseases, and impacts crop quality. Think of it as managing the "sweatiness" of the growing environment - too much humidity can cause mold, while too little can stress the plants.

Example Interview Questions
Senior Level Questions
Q: How would you design a humidity control strategy for a multi-level vertical farm?
Expected Answer: A strong answer should cover system redundancy, different climate zones for various crops, energy efficiency considerations, and emergency response plans for system failures.
Q: What factors do you consider when optimizing humidity levels for different crop types?
Expected Answer: Should discuss plant growth stages, crop-specific requirements, seasonal changes, energy costs, and balance between temperature and humidity control.
Mid Level Questions
Q: What problems can arise from poor RH management and how would you solve them?
Expected Answer: Should mention issues like mold growth, pest problems, and plant diseases, along with solutions such as dehumidification, air circulation, and monitoring systems.
Q: How do you maintain proper RH levels during different growing seasons?
Expected Answer: Should explain adjusting for summer humidity vs winter dryness, using equipment like humidifiers and dehumidifiers, and monitoring systems.
Junior Level Questions
Q: What is the ideal RH range for most indoor crops and why?
Expected Answer: Should know that most crops do well between 40-60% RH, and understand this helps prevent mold while maintaining plant health.
Q: What basic equipment is used to measure and control RH?
Expected Answer: Should be familiar with humidity sensors, humidifiers, dehumidifiers, and basic climate control systems.
