These Leca balls are most used with succulents, cactus and Adenium plants. Due to smallest size, these balls do not have large air cavities inside. Very small air cavities may be found. However, some gardener prefer to use it for drainage and upper soil cover of cactus plants. Use of this size Leca can be an alternative to use of river sand in potting mix. Because these Leca are lighter than river sand. These smallest sized Leca balls (size 3 to 7 mm) are used in gardening and hydroponics. These balls can absorb water upto some extent. Additionally, they are used to make soil-less potting mix for succulents and many more plants. All other larger sizes of these Leca balls are also available with us. These are used as soil conditioner for plants. These clay balls are light weight and ensure better health of plants.
It is suggested that this smallest size of Leca is having very small air cavities inside, hence we should also use approximately 50% Leca of medium size (8-14mm) also in potting mix, so that root growth can be better due to availability of larger air cavities inside them. Larger air cavities help in better aeration of roots. This smallest size of Leca will be helpful in temperature control of potting mix during extreme hot or cold weather and for better drainage.
Use of Leca for mulching (top dressing) of plants is very useful. Leca balls helps plants in protection from weather adversity(i.e. Winter and Summer). Leca Balls are used for thermal insulation in construction industry.
Moreover, volume of these Leca is more than stones, hence in purchase of less Leca Balls, you can cover more area of soil with this. On contrary, if you buy stones/pebbles, you need to spend more for buying more weight of stones. If we use traditional pebbles /stones over soil of plants, roots aeration is hampered upto some extent due to heavy weight of stones. In addition to this, stones are not capable to absorb moisture. But Leca balls can get moisture and contribute in creating humid atmosphere around plants and succulents. Requirement of humidity is most important, especially during hot summer.
