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:
