“I would like to stress that this is a critically important issue, one that can detrimentally affect the future of green roof development in North America. Our ‘best practices’ cannot simply be based on opinion.” the reported research papers use growing media designs based on the fll guidelines. No one is using organically based media in their research. In conclusion I would like to stress that this is a critically important issue, one that can detrimentally affect the future of green roof development in North America. Our “best practices” cannot simply be based on opinion. I suggest that based on the current evidence; the European experience, past and ongoing research and numerous books on the subject we need to focus on mineral-based growing media. No doubt the last word has not been spoken and there is much room for further research in growing media design. J. C. Torenvliet, ZinCo Canada Editor’s Note: Thank you for your comments. In the same issue, we also presented an alternative viewpoint on the subject of growing media by Chuck Friedrich who made the argument for non-organic based growing media. In case you missed this issue, please review both articles online at www.greenroofs.org/magazine – and look for the link to “growing media debate.” Green Roofs for Healthy Cities has established a Growing Media Technical Sub-Committee that is comprised of 10 industry experts and which is developing performance based standards for growing media.
