Thanks for your enquiry. We have a product that we call “Growing Medium” but it’s a blended compost product mixed with sand. It might be helpful if you’re local to pop up and see us so you can see our range and decide which product might best fit your requirements. If you’re unable to pop up perhaps give us a call to discuss and let us know what kind of sand you think would be most suitable. We supply flint sands, silica sands, granite sands, limestone sands etc.
