Bamboo is a special plant which grows extremely fast, in fact, bamboo grows one third faster than the growing fastest tree. Some species (there are about 1200 in the world) can grow up to 3.3 feet a day and up to 60ft within 90 days. Bamboo grows so fast that you can almost "feel the growing". Bamboo is truly nature's renewable resource. Bamboo does not require replanting after harvest, Since mature bamboo has an extensive root system that continues to send up new shoot for decades. The bamboo we use, primarily the Moso specie ( with floss on the surface ) grow in anji county, Zhejiang province (southeast of China), which has to grow for 4 to 6 years before harvest, And at that time the plant reaches 90' in height and 8" to 12" in diameter, this Moso bamboo is the hardest of all the bamboo species and used for our flooring make up to 6 feet long as well as 100% bamboo paneling and plywood up to 8' long and 4'wide
