As urban populations continue to grow, so does the need to address local issues including food security and accessibility. Green walls, particularly those used in Vertical Farming (VF), have potential for abundance in urban environments and may also provide secondary benefits relating to equity and community engagement. Coupled with advancements in 3D printing technology and the advent of bio-composite filaments, this study aims to utilize 3D printing to establish a baseline for cultivating food crops in bio-composite substrate. Test panels were fabricated using three different filament types: 100% pure PLA (polylactic acid), PLA with 11% wood powder, and PLA with 30% wood powder. Our findings show that there is a statistically significant difference in plant growth between filament types, suggesting that the higher the percentage of organic material present within composite filament, the higher the chance for wicking and moisture retention to occur, thereby increasing plant production and viability.
