I am using Miracle Gro moisture control potting mix in my container garden of peppers/tomatoes.
My philosophy when it comes to gardening is to be as Eco friendly and cost effective as possible. If the cost of produce in my garden is not comparable to buying, then I consider my garden a failure.I believe cost is a somewhat decent gauge of the carbon footprint involved.
I believe this too be opposing, conflicting ideal. Chemical vs. Eco friendly.
When comparing cost to quality, I believe produce at the grocery store will be cheaper every time. Cheaper has two means in my book. Less expensive and of poorer quality.
I'm willing to pay more for seed and material, to get fresh home grown organic produce.
For most of us, gardening is a hobby, so expense may not even be a factor.
