IMPORTANT
Please always make sure to use a good quality, suitable growing medium in your terrarium as it plays a crucial role in the overall health and growth of plants. Poor soil or not suitable for terrarium soil can lead to poor drainage, waterlogging, and poor nutrient uptake and result in weak & unhealthy ecosystems. Good quality soil ensures that your plants and moss have the proper environment to thrive, promoting healthy growth and long-lasting beauty in your terrariums.
700g fill in a 1.8-litre container. Suitable for large terrariums (for example 45cm height & 23cm base).
Please note that in an effort to minimize packaging and waste in our shop, we may pack larger quantities of our products including soil, into larger bags. For example, if you order 2 bags of 300g, you may receive one bag with 600g of the product. This is to reduce the amount of packaging and waste and be more eco-friendly. If you have any concerns or special requests regarding the packaging of your order, please contact us before placing your order. We are committed to being environmentally responsible and appreciate your understanding.
