        • "

        • We developed this formula over 40 years ago for the professional Orchid Grower to help his plants set abundant buds that matured fully into vibrant, beautiful and colorful flowers. The 1-3-2 ratio is still the ratio that is preferred by professional growers when they want results. This formula also contains a higher level of magnesium, a vital secondary element, which helps keep leaves green."

      When to Apply

      For best results, apply every 7-14 days, just like a thorough watering. Use this high phosphorus formulation during periods of bud set to increase the number and size of blossoms.

       

      For small volume mixing

      Dissolve the following amounts in 1 gallon of water. Injectors should not be used.

      1/2tsp.     =    67.5 ppm

      1tsp.        =    125 ppm

      1tbspn.    =    375 ppm

       

      When using a Siphonex or Hoze-on proportioned

               1:15 setting                    E.C.

      100 ppm    =    2.0 oz.            0.98

      For Best Results

      Jack's Fertilizers are made with 100% soluble raw materials that will form a true solution. 

       

      For best results, use warm or hot water (180 F°) to dissolve product. Some raw materials are slower to dissolve than others. Most fertilizer compounds dissolve in an endothermic reaction, which means they absorb heat from their surroundings during the process. In strong concentrations or stock solutions (1-3 + lbs. per gallon), using cold water in a cold environment will drastically slow the dissolving process (up to 24 hours to form a true solution). In all conditions, agitation will help speed up the dissolving process by exposing more particle surface area to the water.
