Pulovin 2.5lbs Mix Horticultural Lava Rocks – 1/5 inch Substrate for Succulents, Cacti, Bonsai & Terrariums

Meet Pulovin 2.5lbs Mix Horticultural Lava Rocks, a natural substrate designed to support healthy, well-drained plant growth. These stones average about 1/5 inch, with a subtle variation in shape that adds a touch of natural texture to pots, beds, and terrariums. The blend of lava rocks and gravels leans toward slightly acidic properties, making it a thoughtful choice for acid-loving plants such as succulents, cacti, and orchids, while remaining versatile for a variety of decorative setups.

The rocks are naturally porous, helping regulate soil moisture and encouraging steady air flow around the root zone. This combination can contribute to improved drainage and better root environment, supporting overall plant health without making guarantees. The stones are formed by the cooling and solidification of molten rock, resulting in natural, durable material that is free from harmful substances and safe for everyday use in plant care.
