Well worth doing!
Start with the easy stuff – Tomatoes, Lettuce, Salad Greens, Chillis, Swiss Chard – but the real challenge is in getting self-sufficient in grains, legumes, onions, potatoes – the bulk stuff that really keeps us alive. And then on to the really hard stuff like Sunflowers for oil.
We have been self-sufficient for Beans for the past couple of years, but grains are a still-outstanding challenge. Self-sufficient in Onions the year before last, but last season our supplies were seriously depleted by a Baboon that ate most of the Onions while they were drying out on racks. :-O
The goal is to eat a Totally Self-Produces Pizza dinner – including the beer.
Http://mikro2nd.net/blog/planb/ is where I write about this stuff. Also should have a website up in a couple of weeks about our self-sufficiency project/permaculture/farm at http://mikro2nd.net/.
