There is a difference between best and acceptable range in temperature. Different growth cycles require different environmental climates so your temperature and humidity can vary to keep up with the plants cycle. That temperature range is just a good number to shoot for. Experienced growers will very the humidity and temperature to match the cycle of the plant and get tremendous results.
