Hose is a very important part of your Automatic Watering system as it transports the precious water around your garden from the tap and delivers it to your plants.
There are two types of hose available to build an Automatic Watering system. The first is 13mm in diameter and is the main supply hose to transport water closer to your plants. There is then a 4mm diameter hose which runs off the larger hose and gets water right to your plants.
Both of these hoses can be cut to your exact requirements so you can build a watering system bespoke to your garden.
