Pumice Stones (Matanghito, Monggo, 1cm, Corn)
Pumice stone is one of the most essential component of cactus and succulent soil mix. It promotes good drainage and reduces water runoff and fertilization by increasing soil absorption in sandy soils. It also absorbs excess moisture so roots don't rot.
Finer sizes tend to retain more moisture, while larger-sized pumice will retain less moisture.
