Using my dad's f250, we went once and got 1 yard at a time (2 total).
Then I think ive used 2 of the 10lb blocks of coco coir and 1 of those 4 cubic ft bags of perlite (all of which thru amazon delivery).
I also had some natural clay soil from ny back yard that I dug out to level my shed and mixed that in but that was probably only 10% of total volume.
That plus the fertilizer was what I used to fill four 2'x4'x1' beds, one 4'x4'x1' bed, one of those 8'x4'x1' oval aluminum beds, four 10 gallon grow bags, and 18 5 gallon grow bags.
Ill do a full cost analysis since now I'm curious myself plus might be helpful for people that read this thread.
