Emerald Harvest Cal-Mag final reviews and its price

We really like to be able to express our own review of these type of additives and supplements because is specially interesting in products like Cal-Mag, where we can directly compare it with similar products from competitors.

The first comparison is clear, as Cal-Mag is an all-in-one product that contains a balanced blend of Calcium, Magnesium and Nitrogen. This studied formula allows you to correct and solve any lack of these elements that could occur during growth quickly, easily and not less important: cheap. According to this line of a simple application product, being an all-in one, you don't need to buy and dose three products. With only one product of high concentration you will solve three defficiencies at once. This makes from Cal-Mag a much more efficient product, being cheaper than most of its competitors.

Is specially when we discuss about price where Cal-Mag overstands again, as it needs a much lower dose than other Calcium and Magnesium supplements, but it is also cheaper than those, with a very bargain price so hard to beat (more when talking about purchasing three different additives separately).

If we add all these benefits, together with the kelp extract content, what directly affects in getting quicker results, so in the quality of the product, we are facing one of the best and most cheap supplements of Calcium and Magnesium in market.
