How to Use
For small volume mixing
Dissolve the following amounts in 1 gallon of water. An injector should not be used.
1/2 tsp = 125 ppm
1 tsp = 250 ppm
1 tbspn = 750 ppm
When using a Siphonex or Hoze-on proportioner
1:15 setting E.C.
100 ppm = 1.0 oz 0.64
200 ppm = 2.0 oz 1.28
300 ppm = 3.0 oz 1.92
Limit of Solubility in Hot Water = 3.5 lbs per Gallon
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.
