650L Pine Modular Slot-Down Wooden Compost Bin Extension Kit

Double your organic composting capacity with the Slot Down Compost Bin Extension Kit. Designed to integrate seamlessly with the existing Slot Down Compost Bin, this three-sided add-on bay shares a common upright post to create a professional two-bay rotation system on a compact footprint.

A multi-bay setup allows you to fill one bay with fresh waste while the second bay matures into rich, crumbly organic compost. Built from the same thick pressure-treated timber boards with removable front slats and protected by a 15-year anti-rot guarantee, it provides the ultimate closed-loop soil builder for your garden.

Why You'll Love It:

• Doubles Composting Capacity: Shares a central post with your primary bin to build a compact two-bay composting station.
• Professional Crop Rotation: Keep one bay active while the other cures into ready-to-use nutrient-rich mulch.
• Removable Front Slats: Slide boards out effortlessly to turn heaps or shovel mature compost into a wheelbarrow.
• Continuous Aeration: Spaced wooden slats provide optimal oxygen flow for accelerated thermal breakdown.
• 15-Year Anti-Rot Guarantee: Pressure treated to ensure long life under constant warm, damp compost contact.
• Solid Timber Construction: Heavy-gauge rough sawn boards built for decades of rugged garden use.
