pH Management is a fundamental skill in urban farming that involves monitoring and adjusting the acidity or alkalinity of growing environments. Think of it like maintaining the perfect balance in soil or water that plants need to grow healthy. It's similar to checking the water quality in a swimming pool, but for plants. Farmers use this knowledge to make sure their plants can properly absorb nutrients, which directly affects crop quality and yield. Other names for this concept include "nutrient balance management" or "soil chemistry management."

Q: What factors affect pH levels in an indoor farming system?
Expected Answer: Should be able to explain water quality, nutrient solutions, growing medium choice, and plant uptake patterns in simple terms, along with basic correction methods.
Q: How do you train new staff on pH management procedures?
Expected Answer: Should describe creating easy-to-follow procedures, hands-on training methods, and ways to verify that staff understand the importance of proper pH maintenance.
Q: What is the ideal pH range for most crops, and how do you measure it?
Expected Answer: Should know basic pH ranges (usually 5.5-6.5 for most crops), be familiar with pH meters and testing strips, and understand basic recording procedures.
Q: What steps do you take if you notice pH levels are outside the optimal range?
Expected Answer: Should be able to describe basic adjustment procedures, when to alert supervisors, and basic documentation requirements.
