How to Use

For over 40 years, 1-2-1 ratio fertilizer has been used to keep indoor grown plants vigorous and healthy. Used in a constant feed system (¼ tsp. per gallon), it keeps the nutrition levels constant preventing nutrient stress from over or under feeding. 

For Small Volume Mixing

For Indoor plants: 1/2 tsp. per gallon of water every other week or 1/4 tsp. per gallon every time you water your plants.

This product can also be used outdoors (1 tbsp. per gallon rate) as a transplant solution and as a blossom booster for all flowering plants.

 

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

1/2 tsp.   =   94 ppm

1 tsp.      =   88 ppm

1 tbsp. =   564 ppm

 

When using a Siphonex or Hoze-on proportioner

1:15 setting                               

100 ppm    =    0.7 oz.               

200 ppm    =    1.4 oz.               

300 ppm    =   2.7 oz.               

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.
