Adding growing media

Now it is time to add the growing media and in our case the expanded clay pebbles.  First make sure the gravel guard is in place.   Some water in the growing bed is helpful as the clay pebble will float and fill in around the guard.  As more pebbles are added they will hold the guard in place.


Fill the pebble up to the edge of the gravel guard.


If any pebbles fall into the gravel guard they will have to be removed. The pebbles will cause the bell not to be able to break siphon.


This little guard is to watch the water flowing into the grow bed. It is not necessary but I like to monitor the water flow. It is made from a 2" net pot cut in half.
