Compost Bins: Drill Holes in the Lid?
Yes. I didn't drill holes in mine for a while because I just left the lid off, resembling my larger sized cubic yard compost bins. However, using a lid with plenty of holes can offer the same benefits- good airflow and it allows rainwater to penetrate, too. Now that it's summer, compost systems need more moisture to work effectively... keep them damp, and if you want to use a lid, drill holes to contain the process without hampering it.
