What soil/compost/other materials do you recommend to go into the garden bed where the Subpod is going to be used. We will be growing vegetables.
If you are growing vegetables in your raised garden bed, it is worth using a premium grade of soil, not potting mix. Potting mix is designed to hold a lot of water, but for a raised garden bed, it is better to have well-draining soil.
For example, a good soil that I would like to use will have ⅓ rough sand, ⅓ clay, ⅓ peat/sustainably sourced shredded coconut husk. Depending on the size of your raised garden bed, it may be more economical to source this directly from a landscape supply store rather than buying bags of soil from a supplier like Home Depot or Bunnings.
For the Subpod Grow Bed on our website which is 90cm/ 3 feet long x 120 cm wide x 45 high, after subtracting the volume occupied by the Subpod in the bed, you will need 0.35 cubic meters of soil/ 340 litres of soil, e.g. 7 x 50 litre soil bags or 14 x 25 litre soil bags.
For a larger bed, say 90cm/ 3 feet wide by 1.5 m/ 5 feet long, by 35 cm/ 1 foot high, after subtracting the Subpod volume, this requires ¾ cubic meter or 1 cubic yard of soil. I would add a maximum of 20% compost to the total.
