    EcoLet™ system bulking blend

    WCT | Eco Mix 40

    NZ-made, multi-organic bulking agent engineered to New Zealand conditions and aligned with the manufacturer’s guidelines for EcoLet™ systems.

    A proprietary, multi-organic blend formulated for high biodegradability and strong hygroscopic performance. Tuned to New Zealand humidity and temperature ranges, Eco Mix 40 keeps your EcoLet™ composting mass aerobic, balanced, and working the way it should.

    40 L bag/Approx. 10 kg average/EcoLet™ 240 Series/Starter bed and top-up use

    Why it’s premium

    • Optimised for NZ conditions: Updated ratios for faster moisture uptake and steadier performance in coastal humidity and cooler alpine temperatures.
    • Consistent composting: Maintains porosity to prevent compaction, encouraging aerobic breakdown and odour control.

    • Sustainably sourced and NZ-made: Local production and responsibly sourced components, packed in compostable paper bags.
