Cal-Max™ by Grotek works to charge soilless media and bring plants back from common minor deficiencies associated with nutrient imbalance, rapid growth, or overly humid conditions. A must for growers using coir based soils. Available nitrogen stimulates chlorophyll and amino acid production to quickly re-green starved plants. Chelated iron adds more deficiency fighting power for lush green growth. Added calcium helps to strengthen the plant and assist in times of peak growth.

Calcium and magnesium are two of the macro elements that are of major importance to the growth and development of plants. Deficiencies in either one of them will lead to a stuck in growth. Since magnesium and calcium are needed in a rich amount, especially under certain growing conditions calcium/magnesium deficiencies are not uncommon. To make sure that your plants will get the right amount of calcium and magnesium, Dutchpro formulated its own revolutionized calcium/magnesium with added nitrogen to balance out the extra need of nitrogen.

Advanced Nutrients Sensi Cal-Mag Xtra is a new and improved supplement as it not only contains calculated levels of Calcium (Ca) and Magnesium (Mg), but also contains correct amounts of Iron (Fe) and 20 L-form amino acids.

ATA CalMag is a supplement with the aim to provide calcium and magnesium to the plant if there is too little in the nutrient water. Although hard tap water in most countries contains ample calcium and magnesium, a CalMag supplement may be advisable in some cases. Especially when the grower uses soft tap water, such as in large parts of the United Kingdom or osmosis water (demineralised) water, the use of CalMag is even a must for the plant.

Pro Cal is the ultimate in calcium magnesium supplementation and should be used on a regular basis with your Green Planet nutrient program.
