Automatic Bell Siphon 101
This video provides a clear explanation and example of how an automatic bell siphon works for flooding and draining grow beds. The key to having healthy vegetables in your flood and drain bed, is having a good working siphoning system to ensure your plants get plenty of oxygen and moisture. This example uses clear PVC pipe and a clear grow bed to make it easy to see and understand the working components. Clear PVC is not needed or recommended in your aquaponics system as it will promote algae growth; it was used here just for demonstration purposes for this video.
