Nutrient supply with the chemical elements essential biochemical processes. Although nitrogen, potassium and phosphorus are usually the three most important, there are many more who volunteer. Iron, magnesium, calcium and many others are used to feed plants hydroponically, like a garden soil based.

Although nitrogen is approximately 79% of the air we breathe, the plants need to supplement because it promotes the growth of leaves. This is because nitrogen molecules in air (N2) for stable plants will be built. Phosphorus promotes root growth. And finally, potassium helps plants resist disease by promoting the formation of enzymes

Other elements that help plants with some of its other functions. For example, to help supply calcium ions to different parts of the plant and is a component of cell walls. Chlorine causes the chlorophyll that plants use in photosynthesis. And iron helps form the hemoglobin molecule, such as animals, helps carry the oxygen needed for cellular respiration.

If you are a beginner, there are ready-made solutions are available that contain all the essential nutrients and are very easy to process, provided of course is the dose carefully. For example, a teaspoon 1 / 3 calcium nitrate is dissolved in one liter of water, enough for small cuts or plant germination. Flowering plants usually require a slightly higher dose.

Other factors such as temperature and water, are crucial factors in nutrition. The solution and the water must be maintained, in general, at room temperature with most hydroponic gardens.

Nutrient intake of dried plants should generally be avoided, since nitrogen can feel a burn. This is generally not the case with hydroponics, but it is possible with what is called “aeroponics”, in which plants are grown outdoors.

Adjust the tap to use with your plants at night helps evaporate excess chlorine, chlorine evaporates faster than water at room temperature. Mineralized or distilled water makes things easier because it contains useful material.

You need to control pH levels and try to make it as neutral as possible, because, like plants, nutrients are more alkaline the water is absorbed. This can be countered by adding alkaline small quantities of sulfuric acid, or in extreme cases, sodium hydroxide. A test kit will help you, because it enables accurate measurement of pH values.
