Hemp hooded pullover comes in large and medium Organic Hemp Cultivation Conventional hemp farming is already very ecological, since hemp requires no herbicides, pesticides, or irrigation and leaves the ground in a healthy condition. The next ecological step is to eliminate the use of synthetic fertilizers and attain organic certification. At CanadianHempco we have always been devoted to finding the most environmentally conscious solutions in all of our activities. For example, we already produce all of our hemp fiber with strictly ecological methods of natural mechanical processing -- in marked contrast to the harsh chemicals used for processing hemp fiber in China.
