Now you can find in the Grow Shop Piensa En Verde, Pro-Cal from the house Green Planet Nutrientss, a nutrient that covers the entire life cycle of plants of cannabis, which provides an additional supply of calcium, magnesium and iron.

Although not necessarily deficiencies of calcium and magnesium due to water occur when plants grow very quickly and flowering period is lengthened, sometimes need this food supplement.

is a not very movable element and needs a good flow within the plant to reach the area where it is required.

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 part of the chlorophyll in all plants. Magnesium also is the central core of the chlorophyll molecule in green plant tissue and essential for photosynthesis. Thus, if magnesium is deficient, the shortage of chlorophyll results in poor and stunted plant growth.

Magnesium also helps to activate specific enzyme systems. Enzymes are complex substances that build, modify or break down compounds as part of a plants normal metabolism. Enzymes are essential for every process in a plants life. Unless enzymes are active everything grinds to a halt.

Fe EDDHA - Fe EDDHA or Iron Ethylenediamine-N,N’-bis(hydroxyphenylacetic acid) is a mouthful but is a very important substance. 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 specifically phosphorus thus rendering it unavailable. Therefore iron needs to be chelated or protected ina way that makes it available to the plant across a wide pH range.

Iron can be toxic at very low pH values and completely non available at high pH values, to get around this and to keep the plant happy we use a chelate called EFFGA whoich binds iron and portects it form other elements and keeps it availabel for the plant in a pHJ range of 3.5-9.0. Very important if you are using fertilisers in soil where pH values can drigt into the alkaline zone.

Fe EDTA - Fe EDTA or iron Ethylenediaminetetraaceticacid is also a chelate that is used to keep iron available in a pH range below 7.5 which is ideal if you are using hydroponics. Pro Cal utilises different chelates to make sure that elements are always in a useful form and are not wasted.

Low Molecular Weight Humic Acid -
Also known as fulvic acid, plays a vital role as a chelater of essential minerals and organic compounds allowing them to pass through the cell membrane 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 is more easily available for the building of new growth.

Pro-Cal Features:
- Thick cell walls
- Helps form calcium pectate
- Iron chelated
- Notable increase in size
- Improves the function of enzymes

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 througout the vegetative and flwoering stages and ceasing use in the last week of the flwoering stage which is usually a flush week incorporating Finisher, Liquid W-8, Zyme and water.
