Why Use DIF?
University studies of DIF reveal that plants are most sensitive to changes in temperature at dawn. Using negative DIF controls the elongation of your plant stems. Positive DIF warms the chemistry of the plant cells to get them ready for the upcoming day to rapidly grow new roots, leaves and flowers. Using DIF also conserves chemicals, water and controls foliar disease.
