Jack's Dark Weather 15-0-15

Jack's Dark  Weather formula is one of our most popular when growers are looking for a  way to increase calcium into their fertility program.  An ideal product  for growers who want a non-phosphorus, high nitrate product with  calcium. Alternate with 20-10-20 Peat-Lite or use as a "finisher" for  flowering plants like poinsettias. This formula has the traditional  micronutrient levels needed for general production.

Mixing Instructions

Chart  displays the amount of dry fertilizer (oz.) to add to each gallon of  water to make a concentrated solution. Please check your injector  setting before use.
Limit of Solubility = 7 lbs per gallon

Important Notes:
E.C.  value is the best method to determine fertilizer strength. Fertilizer  appearance may vary in color due to variation in raw material size and  tracer dye distribution upon the particles in the bag. In solution,  color will remain consistent.
​For  best results, use warm water to dissolve product. Jack's fertilizers  are made with 100% soluble raw materials that will form a true solution.  Some raw materials are slower to dissolve than others. Keep stock tank  covered to reduce light and debris inputs.
