Perlite 3 liters

Small white lightweight beads resulting from heating volcanic rocks. Many believe they are fertilizer or cork, which is not correct. As a result of heating, their size increases 20 times, producing small air cavities that retain water and fertilizers to make them accessible to plant roots. They are considered one of the best soil conditioners, helping plant growth and making the soil soft and moist. They improve soil aeration and drainage of excess water. They are non-degradable and remain in the soil. They act as an insulator against high and low temperatures outside the soil. A certain amount of sand equal to four times the amount mixed with perlite is suitable for large pots to facilitate carrying and transportation. They are added at a rate of 20% to the soil.
