Mel's Mix-What am I doing wrong?
I'm baffled and sure hope some of you can help me. I know this is a little tedious, but sure would appreciate your advice. I've looked through the past posts and haven't seen this problem addressed before.
I am just getting my beds set up and filling with Mel's Mix. The beds are 3x3x10, which I calculate to be 7.5 cu.ft. per bed. For convenience, I rounded to 8 cu.ft. and figured how much of each ingredient I needed to fill 3 of the beds. Of course, it came to 8 cu. ft. so I bought 2 bags of vermiculite (4 cu ft each), 8 bags of compost (1 cu ft each), and 1 bale of peat moss (3.9 cu ft which, as I understand it, should expand to 8 cu ft). Only - here's my problem - the mix only filled 2 beds! There was enough left over for maybe 1/4 of a third bed, but certainly not enough to fill it!
Where did I go wrong? Did I make a math error? Has anyone else experienced this? Except for the expense of it, I really wouldn't be too concerned, but I find I'm spending more than I want to on this project! I know I'll be embarrassed if I've made some glaring error, but tell me anyway!
Thanks in advance,
