I recently returned to America from spending 9 months in Ireland as a WWOOF'er.
I came back and began to work on this small farm in southern Oregon.
It was my first experience with growing vegetables in a raised garden bed called a Hugelkultur. (refer: richsoil.com)
Are there any farmers in Ireland (WWOOFing hosts) who use this method of raised beds for growing vegetables?
I think it would work well in a polytunnel.
I would be interested in learning from your experiences.
