Leca ball, short for Lightweight Expanded Clay Aggregate, is an innovative and sustainable alternative to traditional soil for urban rooftop gardening. It is a lightweight, porous, and pH-neutral growing medium that provides excellent aeration and drainage for plants. Leca ball is made from natural clay that is expanded at high temperatures, resulting in a durable and reusable material that is perfect for rooftop gardens.

One of the key benefits of using Leca ball in rooftop gardening is its sustainability. Traditional soil often requires frequent replacement and can contribute to water runoff and pollution. In contrast, Leca ball is a long-lasting and eco-friendly option that can be reused for multiple growing seasons. Its lightweight nature also reduces the structural load on rooftops, making it an ideal choice for urban gardening applications.

In addition to its sustainability, Leca ball offers excellent moisture retention and nutrient distribution for plants. Its porous structure allows for optimal root aeration and prevents waterlogging, while its neutral pH ensures that essential nutrients are readily available to plants. This makes it a versatile and effective growing medium for a wide variety of rooftop plants, including vegetables, herbs, and flowers.
