This is a base with a form for plants for the IKEA Glass dome listed below:
http://www.ikea.com/us/en/catalog/products/40327303/
The base has a form which allows you to easily stack rocks, activated charcoal, and your soil while still making the glass dome removable. I then hid the form with moss.
Moisture loving plants like ferns work best in a system like this.
