|Let’s get started:
1. Take your jars and place an inch layer of stones. The stones act as an interface between the perlite and soil layers. You should see the water line at this layer when watering, you stop when it’s at the very top of the stone layer.
2. Add approximately 1/2 inch to an inch layer of perlite soil on top of the drain stone.
3. You can now add a thin layer of charcoal, if you wish.
