Khay Đá Giữ Ẩm Cho Cây (Humidity Pebble Tray)

Need to increase humidity around a plant without turning your house into a tropical forest? Add this humidity pebble tray.  Just add water and your pebble of choice.  

In order to be waterproof, add plenty of walls as well as top/bottom layers.  At the end of the day, it may be a good idea to spray a coat of clear sealant.  

Looking forward to seeing some makes!
