Germination stage: The optimal germination temperature for cauliflower seeds is 20–25°C. Within this range, seeds sprout rapidly with high germination rates.

Seedling stage: The ideal growth temperature for cauliflower seedlings is 15–20°C. At this temperature, seedlings develop robustly with well-established root systems, producing thick, deep-green leaves and strong stress tolerance.

Rosette stage: The optimal temperature for this phase is 15–20°C. Under these conditions, plants perform photosynthesis efficiently, accumulating nutrients to establish a sound foundation for head formation.

Head formation stage: This critical growth period requires temperatures of 15–18°C. Within this range, heads develop compactly, maintaining a pure white colour and excellent quality.
