When the plants are grown exclusively for fiber, they are planted so close, that the stems become taller and thinner with long fibers. Such plants are harvested before flowering, because the quality of the fibers in the plant declines, with flowering. The stems of these plants are cut about two to three centimeters above the ground level. They are left on the ground, for a few days, for drying. Dried stems are processed to separate fibers. The fibers grow outside the woody core of the stem and can have a length of around 3 to 15 feet. Nowadays, special machines are employed for this task and this process is called thermo-mechanical pulping. The fiber produced from this plant is also known as hemp and is used for various purposes.
