Black Volcanic Stones for Indoor/Outdoor Plant Drainage (2lb)

100% Natural Volcanic Stones for Indoor Plants

Natural Composition and Trace Elements Our volcanic stones are natural rocks formed by volcanic eruptions, rich in trace elements. They are porous, lightweight, and offer excellent thermal insulation, breathability, and water retention. These stones are dyed or chemically treated, and are both fading and corrosion-resistant.

Enhanced Growth Conditions These stones provide excellent growth conditions for indoor plants, as they maintain the integrity of the potting soil by expelling excess water and keeping it loose. This improves root permeability and reduces the risk of root rot. The stones also help fix plant roots and absorb nutrients more efficiently.

Customizable Potting Soil Additives Mix these volcanic stones with other soil types to create the perfect potting soil for your plants. They pair well with bark, coconut fiber, perlite, and zeolite for orchids. Mix them with pumice and akadama for bonsai or cactus and succulent soils. These stones can be used in any form—from soil mix to topsoil for various indoor plants like succulents and orchids.

Widely Compatible Uses Our volcanic stones are versatile and suitable for various applications. They enhance home decor, DIY projects, fish tanks, vases, terrariums, fairy gardens, and even bonsai. Their unique properties make them a fantastic addition to both indoor and outdoor gardening projects.

Ideal Size and Packaging The stones are carefully selected to be of perfect size, with a particle size range of 3-6mm (similar to soybean size). Available in red and black, these stones are packaged in a sealable plastic zipper bag. We have sifted and sieved these stones to ensure a consistent and suitable size for both potting mix and topsoil.

These volcanic stones are designed to meet your specific needs, providing exceptional quality and a wide range of applications.
