• Green Wood: Moisture content of 50% or higher. Difficult to ignite, produces a lot of smoke, and burns inefficiently.
• Seasoned Wood: Moisture content of 20% or less. Easy to ignite, produces less smoke, and burns efficiently.

Drying Methods:

• Air Drying: The most common method. Stack the firewood in a well-ventilated area and allow it to dry naturally. This typically takes 6-12 months.
• Kiln Drying: A faster method that uses heat to dry the wood. This typically takes a few days to a few weeks.

Factors Affecting Drying Time:

• Wood Species: Some wood species dry faster than others. Softwoods like pine dry faster than hardwoods like oak.
• Climate: Warm, dry climates promote faster drying.
• Stacking Method: Proper stacking promotes airflow and faster drying.
• Log Size: Smaller logs dry faster than larger logs.

Moisture Content Measurement:

Use a moisture meter to measure the moisture content of the firewood. A moisture content of 20% or less is ideal for burning.
