I don't necessarily agree with the numbers in this article. I bought a few seeds last year and grew tomatoes, courgettes, runner beans, etc - about £40 worth of veg all in. I didn't spend any extra on water (collected rain water) and so I made about £35 'profit'. Sure, I wasn't raising chickens or shooting elk, but it is possible to do a little bit to boost the contents of your larder without spending a fortune.
