1. Circle design, rounded corners, avoid damage stems, flexibility is good, but with the stem radian bending and deformation.
2. Open constructions, very suitable for the early stages of the growth in which stems need more contact with open air.
3. The truss support is pushed over the stem, it's flexibility makes it possible to straighten it out and place it more quickly over the stem.
4. Improved the quality and size that can increased the output. Reduce labor intensity, improve efficiency and save the time.
