Briefly explain greenhouse climate control and one common misconception about it.

# Greenhouse Climate Control Greenhouse climate control involves managing environmental conditions—temperature, humidity, ventilation, light, and CO₂ levels—to optimize plant growth. This is achieved through: - **Heating/cooling systems** (vents, fans, shade cloths, heaters) - **Humidity management** (misters, dehumidifiers) - **Supplemental lighting** for photosynthesis - **CO₂ enrichment** to boost growth - **Automated sensors and controllers** for precision ## Common Misconception **"Greenhouses are always hot inside"** Many people assume greenhouses maintain constant high temperatures, but modern greenhouses actually require *cooling* as much as heating. During sunny days, even in winter, temperatures can soar to damaging levels. Growers must actively vent heat, use shade systems, and sometimes employ evaporative cooling. The goal isn't maximum heat—it's *optimal* temperature for specific crops, which often means preventing overheating rather than adding warmth.
