VPD (Vapor Pressure Deficit)
VPD (Vapor Pressure Deficit) is a key measurement tool used in indoor farming and vertical agriculture to understand plant growing conditions. Think of it as a way to measure how comfortable plants are with the air around them, similar to how we use temperature and humidity for human comfort. It helps growers know if plants can easily take up water and nutrients. When someone mentions VPD in their resume, they're showing they understand how to create ideal growing environments in indoor farms. This knowledge is important because wrong VPD levels can affect crop quality and yield, much like having an office that's too humid or dry would affect worker comfort and productivity.
Examples in Resumes
Monitored and maintained optimal VPD levels in a 50,000 sq ft vertical farm facility
Improved crop yields by 30% through implementing Vapor Pressure Deficit control systems
Developed standard operating procedures for VPD management across multiple growing zones

Example Interview Questions
Senior Level Questions
Q: How would you develop a VPD management strategy for a multi-level vertical farm with different crop types?
Expected Answer: A strong answer should explain how they would create different climate zones, implement monitoring systems, and develop standard procedures for maintaining optimal conditions for various crops. They should mention experience with climate control systems and team training.
Q: Tell me about a time you solved a major climate control issue in a growing facility.
Expected Answer: Look for answers that demonstrate problem-solving abilities, understanding of how VPD affects plant health, and experience with climate control equipment. They should explain their thought process and the results achieved.
Mid Level Questions
Q: How do you monitor and adjust VPD levels in a growing environment?
Expected Answer: Candidate should explain how they use environmental sensors, what readings they look for, and how they make adjustments to temperature and humidity to maintain proper VPD levels.
Q: What VPD ranges do you target for different growth stages of plants?
Expected Answer: Should demonstrate knowledge of how VPD needs change as plants grow, and how they adjust growing conditions accordingly for optimal plant health.
Junior Level Questions
Q: What is VPD and why is it important in indoor farming?
Expected Answer: Should be able to explain that VPD measures the difference between how much moisture is in the air versus how much it can hold, and why this matters for plant health and growth.
Q: What environmental factors affect VPD?
Expected Answer: Should mention temperature and humidity as the main factors and explain how changing these affects growing conditions.
