ACCURATE MIXING, along with KNOWING the RANGE, are a MUST !
You can do a 100,000 little component tasks, (Weighting, analyzing, measuring, diluting, calibrating, ... ) with Absolute Perfection, and Yet, if you do the next task far enough out of range, You are Dead !
Or, in hydroculture, your Plants Die, or they don't perform properly !
Many acids will produce an Exothermic Reaction when they are diluted. This means that they release heat energy. This heat can "boil" the water forming a bubble of steam which will rise to the surface and break, spraying acid about, possibly in your eyes.
Some times a mineral salt may need a day or more to completely disolve. Your dilutions also, need time to become homoegeneous.
Many reactions complete faster in warmer solutions or with agitation.
Endothermic reactions require heat. Some salts will cool the solution when they are disolved.
A good hydroculture solution should actually be within that range. (400 2,000 ppm)
Disolve ½ teaspoon of Epsom Salt in 30 cc. pure water. Disolve another ½ teaspoon of Calcium Nitrate in another 30 cc. of pure water in a different container. Allow them to completely disolve.
Now pour them both together in a clear container and watch closely. Don't blink now ! Presto ! What Happened ?
The elements switched "Dance Partners" !
The new relationship is more stable and at a lower energy level. At this energy level, in this salt concentration, the calcium sulphate becomes insoluable, comes out of solution and settles to the bottom. This is the concept of precipitation and is sometimes used to remove impurities from a solution.
Zeta Potential is a measure of the electrical force that exists between atoms, molecules, particles, suspensoids, cells, etc., in a fluid.
Zeta Potential represents a basic law of Nature, and it plays a vital role in all forms of plant and animal life. It is the force that maintains the discreteness of the billions of circulating cells, which nourish the organism.
The stability of simple inorganic man-made systems is governed by these same laws. The relevance and application of these principles is the subject of this book.
