Product description
Contain 2L (Approx.750gram) and 4L (Approx.1.5kg) of Large Pumice Stone Per Pack (Free Zipper Bag)
Pumice is a very light stone that comes from volcanic rock. Formed from lava, pumice is porous, or full of tiny holes.
The word comes from the Latin pumex, which shares a root with "foam.
Pumice are porous aggregates, meaning they are added to a potting soil to improve aeration and drainage. The addition of perlite and pumice in a potting soil will also increase the moisture and nutrient retention of the potting soil. Due to its weight, pumice provides bulk density to a potting soil.
There are many advantages to growing plants in pumice. It reduces water runoff and fertilization by increasing soil absorption in sandy soils. It also absorbs excess moisture so roots don't rot. Additionally, pumice improves aeration in your medium mix!
