The Template is laid on the floor, centered and trimmed so each end across from the other has approximately the same measurement against its endpoint (wall) thus guaranteeing an accurate layout. The Template is secured with large head nails or staples. The Template also contains holes to allow the glue to adhere to the tile and the floor.

Abstract: A vertical plant support system that is anchored into the ground by a stake to provide a solid support which holds a long hollow rectangular prism that is attached to it. This hollow rectangular prism has holes throughout its length on all 4 sides. A brace-like attachment is then attached to the hollow rectangular prism using the holes as a point of contact at various points of the growth of the vertical growing plants. These braces can be attached at any time during the growth of the plant. Additionally, there is a connection piece that connects 2 hollow rectangular prisms in order to vertically extend the height of the support system. This allows the full vertical support system to grow indeterminately along with the plant. This support system supports the plant from a lower elevation to a higher elevation, in response to the growth of the plant.
