The most important part of hydroponic plant growth is the right one. preparation of the solution. You can relax, then you are mistaken. It is important to note that this is true. Of course, you can’t bother with this, but in this case, it will be terribly far from the expected.
In the current environment, most are buying ready solutions, produced by industrial means. It is much easier than prepare a solution Please verify the necessary proportions. However, in the conditions of autonomous existence, preparation of the solution have to do it yourself. This is what our article will be about.
The nutrient solution consists of water, macronutrients and trace elements. It is no additional salts, which greatly simplifies the proportions of micro and macro elements. It is not water that has been distilled since it can be distilled. If, however, you need to use the water or tap water. Concentration preparation of the solution. But we’ll talk about it another time.
As for the macronutrients, they are. We are interested in the following elements:
- Nitrogen. The organic component of the organic compounds has been Contained in salts of nitric acids. Shortage – planting leaves Search and lack of lighting – nitrates.
- Phosphorus. Need for the normal course of photosynthesis. Especially important in the early stages of development. Contained in various phosphates. Shortage is the leaves of the plant itself, it is slowing down or even stops.
- Sulfur. It is necessary for the formation of amino acids and enzymes, and it also participates in the respiratory cycle. Shortage – first the young leaves Begins to die off the root. With a simultaneous lack of oxygen – decomposition of sulfur-containing compounds is possible.
- Potassium. The catalyst of the cytoplasm. Shortage – burns out, then it becomes an inter-burn burn. The leaves themselves are dome-shaped bend.
- Calcium. It is important that it helps to ensure that it is normal for the pH of cells. Lack – regional burn, twisting of young buds. There is also an accumulation of mucus on the roots.
- Iron. Chlorophyll and cellular respiration. Shortage – young buds. Old leaves do not change, because they are already a stock. Complete growth stops completely.
- Magnesium. Chlorophyll and high-energy processes. Shortage – green leaves remain yellow. The growth rates are slowing down.
It is necessary to trace the elements that are needed. It will not negatively affect your plants. The following elements are:
- Boron. The formation of growth points. Shortage – die shoots die quickly, leaves grow poorly, ovaries and pollen do not form.
- Copper. Photosynthesis catalyst. Shortage – leaves curl upwards, and their edges turn blue. Also observed the death of young shoots.
- Manganese. The catalyst of redox reactions. Shortage – between yellow and yellow dots that resemble a mosaic.
- Zinc. It is part of the enzymes necessary for certain amino acids. Shortage – interstitial yellowing exclusively in young leaves.
It must be present in the form of a liquid. But as we all know from the school chemistry course, you can stupidly react with each other and give no residue. So, the concentration and method of preparation are to prevent precipitation of precipitation. preparation of the solution. It is the water that has been made. After that, we add 800 ml of water for a large amount of container Then gently add water to a liter. Ideally, no precipitate forms, since the chemical reaction.
It is also extremely important to monitor the pH level. prepared solution. It is a fact that there is a strong oxidation or alkalization of the liquid. It will be possible to observe the results of this process. It is necessary to adjust the pH at each stage.
In principle, there are solutions that can be called “universal” with some stretch. With minor adjustments – for all. Such a solution is a Knop solution. For one liter of water it contains:
- Calcium Nitrate – Ca (No3) 2 – 1 gram
- Potassium monosubstituted phosphate – KH2PO4 – 0.25 grams
- Magnesium sulfate – MgSO4 – 0.25 grams
- Potassium chloride – KCl – 0.125 grams
- Ferric chloride – FeCl3 – 0, 0125 grams
That is, it can be needed by the plant. There are practically no trace elements there, because preparation of the solution The knob is an ordinary water. But there is no need for any trace elements. However, this need is low calcium.
It is a recipe for distilled water. An example is Gericke’s solution:
- Calcium Nitrate – Ca (No3) 2 – 1 gram
- Magnesium sulfate – MgSO4 – 0.5 grams
- Monopotassium phosphate – KH2PO4 – 0.3 grams
- Ammonium sulfate – (NH4) 2SO4 – 0.1 grams
- Iron citrate – FeC6H5O7 – 0.05 grams (dissolves better than ferric chloride)
- Manganese sulfate – Mn SO4 – 0,002 grams
- Borax – Na2B4O7 – 0.002 – grams
- Zinc Sulphate – ZnSO4 – 0.001 grams
- Copper sulphate – CuSO4 – 0,001 grams
As for more detailed recipes, It is then fitted to each of the following articles. And, yes, we will tell you about the individual approach. Of course, you can’t take advantage of your experience. It will save both time and money.
