Can you grow as much on a balcony and window sills as on a London allotment? On 1 May 2010 I started weighing the harvests from my London flat to try and find out!
According to the National Society of Leisure and Allotment Gardeners, a 300 square yard allotment produces £1564 a year. As most London allotments are half this size, I set the target at half this: £782.
After twelve months, the total value grown was £899.99 ($1,480), weighing 83.66 Kg

Each week, I estimated the value of the food based on Ocado prices, I explain how I calculate this here.
