    Fantastic to grade down the large venom boulders

    I brought these to scale down from the large black venom boulder and into the mixed black venom gravel. Lovely mix of shapes and sizes.

    We're environmentally friendly

    • 1. Sustainable Packaging

    • 2. Fast Delivery

    • 3. Guarantee

    Your plants will be wrapped with recyclable Honey Comb wrap - sounds cool because it is :). It interlocks which means we don't need to use tape either, reducing our impact on the environment.

    Not only is delivery fast with DPD Express but it's also green as they offset all the carbon their vehicles produce. Guilt free delivery which we're very proud of...

    We guarantee you'll be happy with your order. But if you're not, please contact us so we can resolve. We are 100% here to help and will always do our best to resolve any issues - that's a promise.
