I set up a very similar project last year, the London Vegetable Garden project, where I grew vegetables from the confines of my urban balcony! The blog is here: http://londonvegetablegarden.blogspot.com – feel free to have a look. I wish you all the best for the project and from someone who’s grown veg on a balcony, keep the faith – it may be difficult at times, but you will achieve big things!

Best of luck – I shall follow your progress with great interest!
