Have fun while making biochar

At Pi Fabricators we know that you want to have an awesome garden. In order to do that, you need healthy soil. The problem is buying soil amendments is costly and most don't stay in your soil very long, which leads to your garden's soil being less fertile. We believe you should be able to enrich your soil with the organic matter you grow in your garden. We understand the importance of having a garden that is both beautiful and provides nutrition for your family which is why we developed a biochar producing fire pit.

Drawing explaining how the biochar fire pit design creates a vortex to reburn smoke and how the design prevents air from entering the bottom of the fire pit allowing biochar to form.

Reduced smoke emmisions

The biochar fire pit decreases the amount of smoke produced compared to a conventional fire pit because the biochar fire pit's shape promotes efficient mixing of air that helps to reburn the smoke.
