Sonotube Lowes

Because the sonotube has thicker walls. Also that length and diameter will give me the volume I'm looking for. I already bought a 12" x 48" piece from Lowes which is their biggest, but the walls are only 1/16" thick and I have my doubts to continue the project.

Why do you want that specific brand? Both Home Depot and Lowe's sell concrete forms. That's all they are; a big paper tube.
