I am doing 3 raised self watering containers (4ft by 8ft, 12 inches deep) and it says to use potting mix not garden or top soil having trouble trying to find out how much I need to get as most are all for raised beds using garden soil or small planters for potting mix. since composition is so different I am thinking it will be different. any help would be great as it appears it will be fairly expensive to fill as not sold in bulk?? thanks!
