With the concept of sustainability as the core, Tea seedling cup uses the tea-branch that is originally but needs to be trimmed regularly as the container material for tea seedlings.

It uses a double-layer structure that contains an appropriate amount of soil mixed fertilizer, so that they can completely protect the roots before transplantation, and after transplantation, it can also extend the time for the tea seedlings to adjust the soil, greatly improving the survival rate of the tea seedlings. The inner and outer pots can be completely decomposed into the soil, reducing the soil burden. It also conforms to the size of planting machines, allowing tea farmers to transplant mechanically and do a lot of planting.
