When the top of the Waterboxx® plant cocoon is covered with sand, the condensation process does not work. The collection of rain is no problem, it will still enter the box. If there is no condensation, you will have less water available. However, the functionality of condensation is not influencing the box’s planting result. In the whole Middle East, and many other desert areas, it is so warm at night, that no condensation occurs. We still have excellent planting results.
