The garden scene used in the hero and guide cover was created with OpenAI image generation on 9 September 2026 as an editorial illustration. It does not depict a measured trial or customer result. The older farmer is an original fictional digital presenter created with OpenAI image generation on the same date. His appearance does not represent a real professional biography or a recorded gardening trial. The irrigation, cover, shade and container diagrams are original SVG illustrations, simplified and not to scale.
