one of the pre done beds that I just seen on amazon are 4 feet by 4 feet by 16 inches high and sell for 110.00 Canadian on sale right now
my other beds are made out of pressure treated lumber and not sure which is the cheapest way and the best way to go here.......
want all new soil to put in the bed.........premixed bedding soil is what I plan on using....
if you dig into the soil here all you hit is rocks. I think we at one time built on a gravel pit here.....seriously
