Below we explain in detail what are the crucial elements to prepare a perfect substrate.

Essential elements to prepare the substrate for a terrarium or Bol Garden

Decorative stone: Decorative stone not only beautifies the exterior appearance of the terrarium, but also provides a unique aesthetic touch. Select stones that complement the overall design of the terrarium and add a touch of style.

Volcanic stone: Volcanic stone plays a crucial role in filtering the water inside the terrarium. It prevents water accumulation at the bottom of the container, thus preventing root rot. Be sure to evenly distribute the volcanic rock at the base of the terrarium for optimal drainage.

Activated Charcoal: Activated charcoal is an essential component in controlling humidity inside the terrarium. It helps maintain a suitable environment for plant growth by absorbing excess moisture and preventing mold or rotting problems.

Mineral substrate: Mineral substrate provides the nutrients necessary for healthy plant growth in the terrarium. Opt for a quality universal substrate that ensures good drainage and nutrient retention for plant roots.

Moss: Moss not only adds greenery and texture to the terrarium, but also helps maintain humidity and provides an ideal substrate for the growth of certain plants. Place a layer of moss on top of the mineral substrate to retain moisture and create an environment conducive to plants.

FicusGinseng and Fitonia: These plants are the main elements of the garden in a bowl, adding color and life to the set. Ficus Ginseng is known for its lush foliage and hardiness, while Fitonia adds a vibrant touch with its striking leaves. Place these plants strategically within the terrarium to create a harmonious and balanced landscape.



Preparing the right substrate is critical to the long-term success of your terrarium or Bol Garden. With these essentials, you can create a healthy and thriving environment for your plants, allowing them to grow and flourish with beauty and vitality.
