Which feature is typical of smart greenhouses?

• A. Manual climate control by farmers
• B. Use of sensors and automation for climate management
• C. Open-air cultivation
• D. Increased chemical pesticide use

Answer: (B)

Smart greenhouses are designed to optimize growing conditions for plants by leveraging advanced technology. The use of sensors and automation for climate management is a hallmark of these systems, enabling precise control over temperature, humidity, light levels, and other environmental factors. This automation allows for real-time adjustments based on data collected from the sensors, which helps in achieving optimal growth conditions while minimizing resource waste.

In contrast, manual climate control by farmers lacks the precision and efficiency provided by automation. Open-air cultivation does not provide the controlled environment necessary for smart greenhouse operations. Increased chemical pesticide use contradicts the sustainability and efficiency goals of smart agriculture practices, which often aim to reduce pesticide reliance through better environmental control and integrated pest management strategies. Therefore, the correct answer highlights the integration of technology in managing the greenhouse environment effectively.
