The pricker is so to say the joist for the capillary hose in the irrigation system, and the mouth at the same time. Using the 16 cm thorn, you can stick it comfortabily into any capable medium for plant cultivation. Then you can watch the irrigation of your plants.
Especially this pricker is very favoured by our customers, because you can literally watch the drops dripping - that makes it easy to control. Normally the water just leaks at the drippers side as a small rill.
In this category you'll find the capillary hose as well.
