Drying
Definition: Drying is the post-harvest step where freshly cut cannabis loses most of its water in a controlled, dark space before curing. Growers aim for about 60°F (16°C) and 60% relative humidity, which typically dries buds in 7 to 14 days. Slow, even drying protects terpenes and prevents the harsh, hay-like smell of rushed buds.
How Drying works
Fresh buds are roughly 75 to 80 percent water. Drying brings them down to around 10 to 15 percent moisture by weight, slowly enough that chlorophyll starts breaking down and moisture moves evenly from the core to the surface.
The 60/60 guideline
- Temperature: about 60 to 65°F (16 to 18°C). Warmer air drives off volatile terpenes.
- Humidity: about 55 to 62% relative humidity.
- Darkness: light, especially UV, degrades THC over time.
- Airflow: gentle circulation in the room, never a fan blowing directly on the buds.
Hanging vs racks
Hanging whole plants or large branches upside down dries slowest and most evenly, which many growers prefer. Wet-trimmed buds on mesh racks dry faster and save space but need closer monitoring. Big, dense colas can hide moisture in the center, so check them carefully for mold.
When it is done
Bend a small stem. If it snaps cleanly with a crack instead of folding, buds are ready for jars. Outer buds should feel dry and slightly crisp, while the inside still feels a little springy. Move on to curing at this point, because drying further makes buds brittle and harsh.
