Halamanin's Pumice (Monggo Size) is an excellent soil conditioner, as it is highly porous, giving your plant excellent water and air holding properties.
No other soil amendment is as widely used by succulent, cacti, and bromeliads growers as pumice because it enhances drainage in garden beds or containers. It absorbs excess moisture so roots don’t rot in wet weather. It is also a natural, unprocessed organic product that comes from mines. Although pumice may appear bone dry, it retains moisture up to 48 hours (in cool weather). It releases moisture slowly, and at a steady rate because the tiny pores on the surface also acts as microscopic reservoirs to store moisture and nutrients and helps to aerate the soil.
