Practical, evidence-led guides for this part of the greenhouse climate system.
Browse chronological archive ↗Learn how passive vents, exhaust fans, intake openings, circulation fans, and controls work together—and how to find the weak link in a hot, humid, or stagnant greenhouse.
Read guide ↗Calculate a source-specific summer exhaust-airflow estimate, convert it to equivalent ACH, check intake area, and compare fan data at static pressure.
Read guide ↗Calculate greenhouse floor area, approximate volume, a source-specific summer exhaust reference, equivalent ACH, and an optional nominal intake-area check.
Read guide ↗Size greenhouse intake openings from stated fan geometry, then check free area, pressure drop, screens, shutters, and staged operation before installation.
Read guide ↗Place the exhaust fan and intake as one airflow system. Use this planning guide to avoid shortcut paths, restrictions, and common layout mistakes.
Read guide ↗Use a practical decision matrix to judge passive greenhouse ventilation, opening layout, weather dependence, restrictions, and when powered backup is needed.
Read guide ↗Exhaust fans exchange air with outdoors; circulation fans mix air inside. Use a symptom-based matrix to find which job or system check is missing.
Read guide ↗Use a practical summer cooling sequence to separate solar load, restricted ventilation, stagnant air, and climate limits before adding equipment.

Practical, evidence-led guides for this part of the greenhouse climate system.
Use a practical humidity-control loop to diagnose high or low greenhouse humidity without relying on one universal RH target.
Read guide ↗Diagnose greenhouse condensation by tracking where and when water appears, then address moisture sources, cold surfaces, stagnant air, and useful air exchange in the right order.
