Sol Soils offers a variety of high-quality soils, soil components, and soil toppers designed for potted cacti, succulents, and houseplants. We select and hand-mix the best ingredients to produce fast draining soils that help protect against root rot, the number one killer of indoor plants. LECA (Lightweight Expanded Clay Aggregate) is becoming one of the most popular and versatile substances in horticulture. As a soil component or medium, it retains moisture while providing excellent drainage for excess water. Many of our customers use LECA in a clear container of vase and put node or leaf cuttings into the LECA and keep the container roughly 1/3 full of water to watch the propagation root quickly and know right away when it's ready for a real potting mix to continue to grow long-term! Use as a soil topper for a unique desert or Martian theme!
