www.Wwoof.net - Usually you live with your host and are expected to join in and cooperate with the day to day activities. In most countries the exchange is based on 4-6 hours help-fair exchange for a full day’s food and accommodation. You may be asked to help with a variety of tasks like sowing seed, planting, wine making, or bread making. The length of your stay at the farm is negotiated directly between you and your host. Some may be as short as 2 or 3 days or as long as 6 months.
