The temperature suitable for the growth of greenhouse vegetables

Tomatoes like high temperatures and germinate when 25℃≤30℃. The room temperature for growth during the day is 27℃. The growth temperature is 10℃, the temperature is 5℃, the lower growth temperature is 0℃, the optimum temperature is 28℃, and the maximum temperature is 38℃.

Celery likes cold. The room temperature is 20 ≤ 22 ℃ during the day and 15 ≤ 18 ℃ at night. The temperature difference between day and night is 4 ≤ 5 ℃. The ground temperature is 18 ≤ 20 ℃, and the lower temperature cannot be lower than 3 ≤ 6 ℃. In the later stage, the temperature is 6 ≤ 8 ℃, otherwise it will not be able to grow and develop.

Cucumbers have strict requirements on temperature. The suitable temperature is 24×26℃ during the day and 14≤15℃ at night. The ground temperature is limited to 10 ≤ 12 ℃. Growth stops below 10 ℃. Above 30 ℃, root activity is weak and leaves shrink. The seedling stage and growth period should not be less than 18℃, and the suitable ground temperature is 20≤23℃.
