I spent $125 USD on Amazon for everything I needed for 50 gallons of Subcool's supersoil, back a few years ago, plus the cost of 2 bags of good organic soil. Like Dankman said, I had enough leftovers to make at least another batch, and I have been adding back these raw components over the years to amend that soil and have kept it going for at least 6 years now. So lets see what my cost per grow for this soil has been, 3 grows per year for 6 years... for $125. That's pretty cheap.... Its still going strong too; using 30 gallons of it in my current grow.
It sounds like you and bobrown are in similar compositions because he gets his tested every so often and it's getting better the more it's used. That's awesome you got so many grows out of yours. What's your average now, like $9 per run, lol?
