Hotter peppers are more tolerant of warmer water than their counterparts, which will become deformed if the water temperature exceeds 80 degrees Fahrenheit (27 degrees Celsius). Because too cold water cannot stimulate pepper growth, the optimal temperature to keep the water at for best pepper growth is between 60°F and 75°F (15.6°C and 23.8°C).
