Abstract: A system for growing a plurality of plants, including a support apparatus having a plurality of upright frames and a plurality of substantially parallel wires extending longitudinally between the upright frames above a base surface. The wires are placed in tension to support laterally therebetween a multiplicity of individual, separable bags containing plants. Cultivation of the plants is facilitated by the apparatus with the supported bags positioned in a minimally spaced arrangement relative to each other at an ergonomic height above the base surface.

Abstract: A modular structural system including a plurality of elongate structural members. The structural members are formed of a fiber-reinforced polymeric material and have a common cross sectional configuration with a circular outer perimeter and two oppositely disposed T-shaped grooves. A central opening is disposed between the first and second grooves. A reinforcement member can be positioned in the central opening for additional strength. Bracket members having first and second flanged edges. The flanged edges can be securely engaged with the T-shaped grooves disposed on the structural members to secure two of the structural members together at an angle. The system may be used as a trellis and wire stays securable in the T-shaped grooves and a pivot bracket are also disclosed. The wire stays include a base positionable in the T-shaped groove and a shaft that extends outwardly. The pivot bracket pivotally joins together two of the elongate structural members.
