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 conentrations 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.
Keep stock tank covered to reduce light and debris input.
Jack's Hydroponic Herb FeEd along with many of the fertilizers in the FeED line of products will have a slightly blue-gray-black appearance in concentrate. This is normal and a result of the types of iron chelates that are used in the blends.
