Calcium is the second most important nutrient in your entire Nutrient lineup. No nutrient processes without sufficient Phosphate. Sufficient Phosphate will not process unless there is sufficient Calcium. Calcium that is applied only in the Vegetative cycle, sets the plant up for a huge Flower cycle. Calcium applied in Flowering cycles pushes out Potassium causing leaf knife tip yellowing. Additionally, the industry typically has Cal-Mag issues, and generally, that is a result of the use of Ag-Limes or improper pH.

There are many different types of Calcium, and their structure dictates its behavior in soil. BlueGold® Cal-King is formulated using Calcite Calcium, which is Oceanic Calcium Carbonate. Ag-Limes like limestone are hydrophobic and very insoluble in water. When combined with soils that are low in microbial activity and organic matter, they take years or decades to move from the top six inches (unavailable) to the bottom six inches of soil (available). Calcite Calciums are very hydrophilic and move very quickly in soils, and they have a biological package attached to the tune of 200,000,000 CFU/g. Calcite Calciums have been proven to carrier negative ionic charges, which can explain on another level how they can react so quickly in soil (a positive ionic environment).


For the Vegetative Cycles: Our BlueGold® Cal-King Calcium source undergoes our trade secret Eden Synergy process. This micronization process maximizes immediate bioavailability potential and combines the micronized Calcium source with our flagship BlueGold® technology. BlueGold® Cal-King is formulated from Calcium Carbonate deposits found deep in the ocean. The BlueGold® Cal- King ingredients are micronized via cold mechanical processes and have been proven to have a negative charge.


BlueGold® Cal-King is an OMRI-listed Input (please contact your certifier before use).

Do not use with synthetically enhanced or high Na/Cl grow media with BlueGold®. By itself, BlueGold® will not harm ANY crop, plant, biology, system, human, animal, environment, pollinator or beneficial (including birds, butterflies, earthworms, etc.). Do NOT combine with pesticides/chemicals/plant cleaners/etc. Very recent or current use of chemicals like fertilizers, herbicides, fungicides, algaecides, bactericides, miticides, pesticides, biocides, fumigants, plant growth regulators, pH Up/Down chemicals, dyes, etc., – all can cause an unfavorable interaction due to the Wetting Agent properties of BlueGold® Solutions, which can magnify the strength of said chemical. Strengthened doses of those chemicals can result in direct stress, burning, or death of plants. BlueGold® Solutions by themselves, without chemical interactions, will never cause these issues in any plant or soil (when used as directed)Users must respect BlueGold® labels and reduce NPK/synthetic inputs by +/- 90%. If by user choice, against our directions/recommendations, to use chemical inputs by combining with BlueGold®, they must be reduced by 90% or more and then dialed up as you see fit. If you encounter problems in the plants from the chemicals by your choice, then STOP. If you quickly move the pH to 6.4 with the help of pH adjusters, without adjusting inputs, you’re drastically making inputs more available, which results in stressed, burned, or dead plants from too big of a hit from the nutrients that are now available at a much higher % than previously. Especially when all the excess stored up chemicals inputs, flood into the plants at even higher EC/PPM values. Likewise, if you do not adjust inputs while using BlueGold®, as soil/sap pH is driven to 6.4, the same can happen over an extended period depending on soil and watering conditions. We do not advocate mixing BlueGold® with any chemicals. This all only applies to chemical-based products and does not apply to organic-based products except for humic and fulvic acids (please start at a 50% reduced rate). If you feel you need more, then start at a reduced rate of 90% and test on a few plants first.

As the manufacturer we offer 100% Guarantee when used as directed, within the Eden Guaranteed Grow Program. A limited guarantee restricted to exclusive use with BlueGold® products and systems subject to soil, sap, water testing conditions, and Postal damages. No warranty or fitment of purpose promised.
