A drying room is a production system, not simply a conditioned room with hanging plants. The goal is to create repeatable conditions across the entire load so flower moves through drying predictably without large wet and dry zones.

Design around the peak load

Size the room and environmental equipment for the amount of water entering at harvest, not for an empty-room condition. Plant mass, harvest timing and loading density affect the moisture load dramatically.

Airflow should be uniform, not aggressive

The objective is to reduce stagnant zones and environmental variation without blasting flower directly. Evaluate circulation patterns at multiple heights and positions in the room.

Dehumidification and temperature work together

Moisture removal capacity, sensible cooling and room temperature are linked. Equipment selection should be based on expected load and operating conditions rather than nominal square footage alone.

Rack and hanging geometry matter

Spacing changes how air moves around plant material. Overloading one area can create slower drying even when the room-average sensor appears on target.

Measure several points

Use multiple sensors or spot measurements to identify gradients near doors, corners, supply air and dense plant zones. One sensor cannot describe a large room.

Plan for cleaning and turnaround

Drying hardware, floors, walls, fans and contact surfaces should be accessible enough to clean between lots.
