What depth is required in a raised bed to bury the Subpod?

You’ll be digging a hole which is: 85cm L x 55cm W x 32cm D (33in. L x 21in. W x 15in. D).  That’s around 8-10cm (3in.) longer and wider than Subpod.  It’s important that the top Airflow panels are above ground.

The walls of the raised bed should be a minimum of 33 cm high (1 foot plus 1 inch).  There is no upper limit to the height, this depends on your preferred working height and if you need a taller bed to limit access by animals.

A good smaller size that will also provide some food growing space is 90 cm/3 feet wide by 1.5 meters/5 feet long.  This will be filled by ¾ of a cubic metre/ 1 cubic yard of soil.

Shown below are a range of garden bed size options if you are building your own garden beds, or adding Subpods to existing garden beds:
