New Millenium Summer Shift 2.5 Gallon Summer Shift Summer (PART B) is a very special season in the New Millenium Fertilizer System™. In nature’s best Mediterranean Summer, the soils warm and nutrient rich colloids rapidly release. This release of nutriment is easily accessible to root systems which enables plants to size up structure and support. Summer is capable of producing healthier flower, fruit, and seed pod sites. This is easily the most robust of all of the seasonal inputs. When used with Equinox (PART A), Summer (PART B) will promote healthy structural development along with dense foliage in mature vegetative plants. Summer may also be used as a supplement, combined with Spring or Autumn, when more nitrogen based vigor is desired. Summer contains copious amounts of many plant available periodic elements and will ensure prolific growth in most stages.
