Green Planet Nutrients - Pro-Cal 1.1 - 0 - 0

WHAT IT IS?
– Pro-Cal is an excellent supplemental source of Calcium, Magnesium and Iron. Plants engaged in rapid growth can often come up short on these essential elements so supplementation is a great idea.
HOW DOES IT WORK?
– Plants undergo a lot of stress and rapid assimilation of nutrients in their quest to build cell walls, produce chlorophyll, conduct photosynthesis, divide cells and other important functions. Calcium is an element that isn’t very mobile within the plant and needs good flow of fluids throughout the plant to pull it to the areas to which it is needed and more importantly the calcium needs to be in a form that the plant can easily transport.
WHY IT WORKS?
Calcium Nitrate
– Calcium is sourced from Calcium Nitrate. Calcium is an essential part of the plants cell wall structure where it forms the glue (calcium pectate) that holds cells together making it essential for new growth, improves the absorption of other nutrients by the roots and their translocation within the plant. It activates a number of plant growth-regulating enzyme systems, helps convert nitrate-nitrogen into forms needed for protein formation and contributes to improved disease resistance. Calcium is an intracellular messenger as well and can send a signal from one cell to another telling other cells how to react or interact. Calcium, Magnesium and potassium live in a balance within plants. Too much of one will inhibit the other two. Calcium is a co-factor in many enzymatic reactions. Its presence is needed to turn an enzyme on or off and allow it to catalyze a reaction.
Magnesium Nitrate
– Magnesium is derived from Magnesium Nitrate providing a readily available source of both elements. Magnesium is part of the chlorophyll in all plants. Magnesium is the central core of the chlorophyll molecule in green plant tissue and essential for photosynthesis. If Magnesium is deficient the shortage of chlorophyll results in poor and stunted plants. Magnesium also helps to activate specific enzyme systems. Enzymes are complex substances that build, modify or break down compounds as part of a plant’s normal metabolism. Enzymes are essential for every process in a plant’s life.
Iron (Fe)
– Iron is essential for chlorophyll production therefore goes hand in hand with Magnesium. The problem with Iron is that it is very reactive with other minerals and will lock up with other elements especially Phosphorous thus rendering it unavailable. Therefore Iron needs to be chelated or protected in a way that makes it available to the plant across a wide Ph range. Iron can become toxic at very low Ph values and completely non available at high Ph values. Pro-Cal uses a chelate called EDDHA which binds Iron and protects it from other elements and keeps it available for the plant in a Ph range of 3.5 to 9.0. Iron Ethylenediaminetetraaceticacid is also a chelate that is used to keep Iron available in a Ph range below 7.5 which is ideal if using hydroponics.
LOWER MOLECULAR WEIGHT HUMIC ACID
– Also known as fulvic acid it plays a vital role as a chelater of essential minerals and organic compounds allowing them to pass through cell membranes much more efficiently. Fulvic acid stimulates enzyme production critical for plant functions. One of the most important functions of Fulvic acid within Pro-Cal is to keep the Calcium fully chelated so that it is more easily available for the building of new growth.
HOW TO USE IT?
– Pro-Cal is the ultimate in calcium magnesium supplementation and should be used on a regular basis with your Green Planet Nutrient program. Pro-Cal is used throughout the vegetative and flowering stages, ceasing use in the last week of the flowering stage which is usually a flush week. Use Pro-Cal at the rate of 5 mls per gallon throughout the vegetative stage and moving up to 7 mls per gallon for the flowering stage.
