Does the Grow Garden Bed have a sealed bottom?

The Grow Garden Bed has an open bottom that is suitable to sit on soil, sand, grass etc, anything where you don’t mind liquid run-off from your garden bed going.
If you want to put your Subpod on a balcony, verandah or concrete, we recommend that you purchase a sealed garden bed or a wicking garden bed.  
At the moment we don’t have a garden bed that we are selling ourselves, but you should be able to find one locally.

Suitable garden beds for verandahs, balconies, patios and concrete will have a hole cut-out where the worm tea outlet is so that a tap can be fitted so that the worm tea is not continually flowing out.
Instructions on how to plumb your Subpod for the worm tea is here:

In a newly built raised garden bed, a good minimum size that will also provide some food growing space is 90 cm/3 feet wide by 1.5 meters/5 feet long.  If the sides of the garden bed are just over 30cm /1-foot cm high, this will take about ¾ of a cubic metre/ 1 cubic yard of soil.
