T don't think there are very many places you can buy, they may be a little more expensive, but you are going to have to build them, well IMO.cool, anyone here know how much a 20inch (diameter) by 2ft (length) Sono tube costs?
You would have to go to a concrete materials supply store. Home Depot and Lowes usually only carry up to 8 inches in diameter. Go to the sonotube website to see the different diameters that are actually available.cool, anyone here know how much a 20inch (diameter) by 2ft (length) Sono tube costs?
