FCMP HOTFROG 37-gallon rolling composter
The 37-gallon HOTFROG changes the composting method to a rolling tumbler instead of managing worm trays.
Read our takeA green four-tray vermicomposting bin with a collection base.
Four trays give an established worm-composting plan room to work through successive trays.
The trays include moisture-retention channels, airflow spaces, and migration tunnels between levels. Those are useful features when you want a managed living system rather than a bucket that simply holds scraps.
Follow the instructions for the material balance and care.
Leave access for loading and collecting finished material.
