Coco soil
I was in Poundworld and happened to notice little blocks of what was called Coco Soil. When soaked, it expands to produce 10 litres. It's the same stuff as Coco Coir and what IKEA used to sell under the name of Kokosnot. I know some people use it instead of topsoil and I have used it myself in the past from IKEA (don't think they sell it now).
I expect it will be a pound each but I never saw a price ticket. They are pretty small blocks, maybe about 6 inches square x an inch thick
