Description
Already have a GrowGrid Trellis Starter Pack? Keep growing. These individual expansion panels and connectors let you customize, extend, and reshape your trellis in any direction — forever expandable, endlessly creative.
All pieces are 3D printed in Omaha, Nebraska from eco-friendly, plant-based PLA and snap directly onto any existing GrowGrid trellis setup. No tools required.
- Foundation Panel — The base of every GrowGrid build. Use an additional foundation panel to start a second trellis, expand horizontally, or create a wider support for larger climbing plants like Pothos and Scindapsus.
- Snap Connectors 2-Pack — The click-together connectors that hold your GrowGrid system together. Stock up so you're always ready to expand. Each connector locks panels firmly in place with a satisfying snap.
- 90° Corner Connector — Take your trellis in a whole new direction — literally. Lets you build around corners, create L-shaped layouts, or wrap your trellis around a pot for full 360° plant support. A must-have for creative builds.
Mix and match to build your perfect trellis layout. Every piece works together seamlessly — just snap, grow, and repeat. 🌿
