Watering device (25 ml)
Description
This is a tiny watering device for a small seed tray. You submerge it under water and close the small opening on top with your thumb. This keeps the water inside the device and you can position it above the seed tray. If you remove your thumb from the opening, air will flow in and the water flows out the bottom. I also added a small ring around the top opening so that it is easier to close it air-tight with your thumb. The devide is designed to dispense 3 different amounts of fluid, two of them are marked on the device: 5 ml 15 ml If you want to use the full capacity of 25 ml you simply have to submerge the device completly.
