I have a not large apartment with a balcony.  Rules of the leasehold prevent me from putting much on the balcony though so in practical terms I only have a very small amount of space in/outside to grow anything.  That doesn't mean I wouldn't like to have a go but I can't see myself doing very well.

I definitely don't have the time (or inclination if I am honest) to get an allotment - the nearest ones I know of are at least 10/15 minutes drive away. I like the idea of growing my own food though.
