Pon is a substrate or growing medium that can be used in place of soil. It is a soil alternative that looks like small stones or gravel and contains high-quality mineral rocks that are free of contaminants and pollutants. Pon is known for its ideal air-water ratio for plants, which is 45% water and 55% air. It is also a favorite for using with self-watering or wick watering for the ultimate low-maintenance plant care. Pon already contains nutrition when purchased, which is effective for about six months, and afterwards, you will have to add nutrition yourself. Pon is not the cheapest alternative, and there is always a chance that a plant can go into shock because of the transfer from soil to pon. However, pon can prevent root rot, fungus gnats, and is way better for roots and growth. Pon is a substrate that is used by plant enthusiasts and collectors, and it is becoming increasingly popular in the plant community.
