Such a simple idea! We found this brass Seedling Mister Nozzle ideal for gentle seedling misting as well as for applying soluble foliar fertilizers like liquid kelp. This device simply screws on most soda or water bottles with an adjustable, high quality brass cone. The nozzle can be adjusted from a fine mist to a course stream. Push and pull the anti-slip handle to spray. This ultra-light tool (160g/5.4 oz and 38cm/15") is a great addition and gift for balcony and patio gardeners. It also works well for orchids and other moisture loving tropical plants.
