Hanging window box 17L, 2 compartments. The hanging window boxes adjust to all widths of guardrails. Placed on the ground, they fit narrow window ledges. Flowers or aromatic herbs, invade the city! Permeable, BACSAC lets the soil breathe and the excess of water flow out. Its technical multi-layered fabric maintains the necessary balance between air, soil and water. Tear strength, abrasion and UV-resistant, the outside fabric can withstand temperatures from -30°C to +70°C. Inside, the combination of 3 layers of felt protects the roots, limits evaporation and distributes water. Place directly the soil and the plant in the BACSAC. The Bacsac in the new colours – ardoise, avocado, cerise, etc – are made of Batyline fabric and non woven felts. This technical double-layered fabric allows your plants to flourish as if they were in the ground. The material allows for both soil to breath and water to drain as needed by the plant, and it is treated against UV. BacSac comes in a variety of shapes and sizes.
