I have done business with Paulownia Seed on 3 occasions, and have visited their plantation in Tennessee twice. I have also visited other companies that offer Paulownia and I can certify that the services received as well as the products that I have purchased from Paulownia Seed are of the highest quality.
I took a two day course from Dr. David Sutton on how to start from seed and go to lumber with Paulownia, that has saved me from making costly mistakes and allowed me to be producing biomass in a very short time. I have done so well that The American Paulownia Association (APA) invited me to be one of their speakers at their yearly meeting in Asheville, North Carolina to present my results with development of intensive Biomass production with Paulownia.
I have found Dr. Sutton to be a very knowledgeable professor on all things related to Paulownia.
