How to use this prompt

The searchable detail is the first true leaves — the pair that comes after the seed leaves — so the prompt names them, which keeps the seedlings at the right delicate stage rather than mature plants. Misting adds action and gives you water droplets, which catch the bright windowsill light and signal freshness. Keep the potting mix dark and moist; dry pale soil reads as neglect. The plant markers and trowel establish the gardening context without pulling focus. Avoid naming a count of trays, because the model will get it wrong — a row of trays is enough.

Variations to try

  • A close-up of one seedling with a water droplet on its leaf
  • Seeds being pressed into the cells of an empty tray
