If you are using clay pebbles as your medium of choice, or indeed any other substrate that doesn’t hold much moisture such as coco, you should definitely consider using a Flood Dripper. This Flood Dripper is free flowing, meaning however much water your system’s pump is pushing out the dripper will release it evenly throughout your system. Blue stake versions are used to automate feeding when you are growing plants in pots. In many cases a digital timer is used to regulate liquid release, as this dripper can release up to 40 litres per hour. The Blue Flood Dripper is particularly useful when the water flow has undergone some kind of pressure regulation, and also if you have a smaller system where your pressure is anyway likely to be fairly evenly distributed. The dripper is made from robust plastic, making it suitable for commercial growing environments.
