Learn what a cedar composter spacer does, why it matters for airflow, and how to install it in your compost bin for better decomposition.
Quick Answer
A cedar composter spacer creates small gaps between compost bin boards to let air circulate, which speeds up decomposition. Install them between the boards as you assemble your composter.
Why Airflow Matters in a Compost Bin
Composting relies on oxygen for the aerobic bacteria that break down organic matter. Without proper airflow, the pile can become compacted and smelly, slowing the decomposition process.
A cedar composter spacer is a simple solution: it holds boards slightly apart so air can move through the bin. This is especially useful for enclosed composters where natural ventilation is limited.
Choosing the Right Spacer for Your Bin
The Cedar Composter Spacer 1.5 in x 1 15/16 in RCPEC2 is designed to fit between standard composter boards. Its compact size creates a gap that balances airflow with structural stability.
Before buying, measure the width of your boards and the spacing you need. If your composter uses thicker boards or you want larger gaps, you may need a different spacer size.
Diagnosis: Is Your Composter Missing Spacers?
- Symptom: Your compost pile is wet, smells like rotten eggs, or decomposes very slowly. These signs often point to poor airflow, not just too much moisture.
- Likely Cause: The boards in your compost bin are flush against each other, leaving no gaps for air to enter the pile. Check if your composter design includes any ventilation holes or gaps; if not, spacers are the fix.
- Corrective Action: Install cedar composter spacers between the boards as you assemble the bin. Place one spacer at each end and one in the middle for even spacing. After installing, turn the pile once a week to help air reach the center.
- Stop or Choose Another Option: If your compost bin already has built-in ventilation slots or you use a tumbling composter, spacers are unnecessary. Also, if your boards are very thick, a larger spacer may be needed. Measure your board thickness before ordering to ensure the spacer fits properly.
