Introduction to the
Multiple Ion Management System (MIMS)


Prior to the invention of MIMS, creating and maintaining nutrient solutions for the various phases of hydroponic photosynthetic production has been a primitive process based primarily on guesswork.  Traditionally, hydroponic growers mix commercially available compounds into water, in the order and quantity specified by their manufacturers, and then try to maintain a temperature and pH range that will allow those compounds to decompose into usable nutritional ions over a period of time. 

Until now, there has been no technology available that can measure or predict the amounts of individual nutrient ions that will be produced once these originating compounds have been mixed in water.  And even if you follow the same "recipe" every time, the decay process for each compound is unevenly affected by many factors including the exact temperature pH, and oxygen levels in the solution and the interaction of the binder materials used to stabilize each of the original compounds.  This means you can never get the same results twice, and there is no consistency available when using these methods.


Not only do you not know the initial concentrations of nutrients in your solution, you also cannot measure or calculate the amount of any nutrients the plants may have consumed from it.  You also have no way of knowing how much useable nutrition may still be available from the continuing decomposition of your original materials.

The truth is that hydroponic growers have no means to add actual nutrients to their hydroponic solution.  They can only add fertilizers that may eventually become nutrients under the right conditions of temperature, pH balance, oxygen levels, and circulation or agitation. 

Fertilizers were developed - and are the right choice - for photosynthetic production using soil as the growing medium. Under the right moisture and pH conditions, the binder materials that make up the vast majority of the fertilizer mass will slowly decompose - releasing charged ions of nutrient containing molecules.  This is usually the result of endothermic or exothermic chemical reactions with water and oxygen combined, with acids and bases previously stabilized in the binder materials.  The fertilizer decomposition process occurs over days and weeks in soil.  The residue left over from it up to 97% of the original mass is typically diluted and degraded over time by other processes in soil. However in a hydroponic environment this 97% waste material does not go away - and it affects the plant roots the same as salt.  This is because any material in solution with water makes it electrically conductive (the same as salt), and so it short-circuits the tiny electrical charges produced in the root systems of plants that facilitate the electrochemical uptake of nutrients.

Because of these problems, hydroponic growers frequently discard their nutrient solutions and rebuild them from scratch, based on their continuing best guess as to concentration and proper pH levels.


At DHC we call the combination of a nutrient solution and its containment a "Battery".  We call it that because a functional hydroponic solution is really an electrolyte.  Indeed the entire process of nutrient uptake by plants is an electrochemical process similar to a battery.  In simple terms, plants can only assimilate nutrient molecules in their ionic (electrically charged) form.  For the remainder of this discussion, the term "nutrients" refers to the ionic forms of nutrient containing compounds regardless of if they are "cations" having a positive charge, such as Nitrogen in salt form - NH4, or "anions" having a negative charge, such as Nitrogen in ammonia gas form - NH3.

DHC has developed two proprietary inventions that completely solve the problems of creating and maintaining hydroponic electrolytes.  MIMS uses these inventions to create and precisely manage a sterile hydroponic nutrient solution in battery cell sizes from 100 - 10,000 gallons.

The first invention allows a computer to accurately measure and adjust the concentrations of 15 individual nutrients in hydroponic solution in less than one hour. This method not only allows the computer to maintain a perfect nutritional blend, it also tracks and records the actual uptake of each nutrient by the plants multiple times per day.

The second invention allows the computer to create individual nutrient ions directly in water, in concentrated precision quantities, using electrochemical processes.  The freshly made-on-demand concentrated ions are then injected into the hydroponic epicenter in 97% PURE form, completely eliminating the "salt load" problems of conventional fertilizers.

In addition to its "day" and "night" differential control of temperature, pH, and oxygen levels, the MIMS computer provides precise measurement and adjustment of 15 critical plant nutrients in real time. 

DHC calls the resulting computer-controlled hydroponic battery cell a HYDROSPHERE.
DHC intends to file for patent protection of its copyrighted measurement and nutritional augmentation methods called MIMS.
