plantable shipping box

We're experimenting with growing edible mushrooms (like shitake, oysters, etc.) in my house;   We were super excited to get our Fungi Perfecti catalog in the mail last week.  On my list of things to order is the Life Box.  These are shipping boxes that grow trees!  That means I can ship my clients albums, etc. in a box that they can shred, plant and it will grow.  Now I just have to figure out how to ensure they do that!  Any ideas?

Why use a Life Box?
Once delivered, a regular cardboard box dies at your doorstep, so to speak. The conventional brown box serves only the purpose of delivering a product. And then, at best, it is recycled. The Life Box is not just a box: it is a teaching tool that unfolds into a continuing, life-long experience. It empowers individuals with the ability to sequester carbon by planting trees and making a positive difference. The Life Box has ‘legs’, or more aptly trees, which will remind the receiver for years to come of their own environmental awareness, and that of the company who shipped it. The shared experience of everyone involved builds a community of those trying to help the planet with a long-lasting and sustainable solution to climate change.

The Life Box may become a palate, a template for eco-artisans and architects to help re-green the planet. The Tree Life Box uses trees approved by every state in the United States that regulates tree movement, and are approved for export to Canada. All species embedded within the Life Box™ are native to the continental US and Canada and are non-invasive. We plan to expand the Life Box line of products to include wild flowers, vegetables, grasses and herbs within boxes, padded envelopes, egg cartons and a wide variety of packaging materials.
