Create a premium commercial hero image for one original unbranded modular desktop growing light. The product combines a curved matte-aluminum arm, adjustable full-spectrum light bars, three small ceramic herb pots, and a concealed water reservoir base. Show exactly one assembled unit with three healthy culinary herbs, plus one detached magnetic light bar placed neatly beside it to communicate modular construction. Use a square 1:1 slightly elevated three-quarter composition on a pale microcement surface against a sage-to-warm-gray studio gradient with generous clean space. A large softbox defines precise edges while gentle warm growing light reveals leaf veins. Emphasize anodized aluminum, fine ceramic glaze, moist soil, subtle condensation, and grounded shadows. No readable interface, logos, watermark, duplicated product, floating parts, fake plastic foliage, impossible cables, or excessive props.
