Hydroponics has several positive aspects, and it is used globally, especially for the production of food, but also for different elaborate crops: it is, for all intents and purposes, a recognized part of agronomy. It is even used for the tea I use to fill my ceramic mug. The advantages of aquaculture are detailed in the following statements.
- It is not required to use soil. Hydroponic cultivation can be implemented even in areas unfavorable in terms of climate or soil conditions.
- Administration of vitamins occurs in a controlled environment, so you cannot experience the waste associated with the actual spreading of fertilizers on the soil, where some can be washed aside by rain or made unavailable simply by chemical reactions. This results even in the absence of pollution for the environment and to the flaps. Similarly, you do not go through the deficiencies sometimes associated with crops in the ground, where some nutrients may be seen in limited amounts.
- Since the water could be reused within the system, water requirements for the crops are greatly reduced. In some instances, you could save up to 70-80% in terms of water usage. This allows you to build in areas that are particularly dried out, and save on the costs of irrigation.
- Attacks by parasites, viruses, and pathogens that normally have a home in the soil are minimized; in the case of disease, it is easier to intervene with all the treatments for plant protection.
- The presence involving herbs and weed is virtually zero, and this eliminates the need for using herbicides.
- The yields are high and stable, and can be from 2 to 8 times greater than the regular growth on your lawn.
- Cultivation can be carried out throughout every season because you grow under controlled conditions, and thus get rid of the seasonal specifications of the plant species. You can also grow completely inside a grow tent.
Among the downsides of hydroponics, we first mention the fragility of the program. Since plants do not have their roots in the soil but are completely dependent on artificial sustenance, any difficulty to the technical system can cause rapid death of the crops. The high level of moisture associated with hydroponics, moreover, favors the development associated with fungal diseases such as wilt.
The techniques of hydroponic cultivation
The particular nutrients used in hydroponics cultivation techniques (also known as hydroponics ) are dissolved in water, and is represented by ions (positively charged) and cations (negative) as
- calcium (Ca ++ )
- magnesium (Mg ++ )
- potassium (K + )
- nitrate (NO 3 – )
- sulfate (SO 2 – )
- dihydrogen phosphate (H 2 PO 4 – )
Typically, the solution is added in addition several essential micronutrients such as
Very useful are the chelating brokers, which maintain the iron in the remedy, making it available to plants, and nutrients such as amino acids and vitamins that can be directly consumed by the plant roots, stimulating emergence and fruit enlargement.get more facts at http://www.bbc.com/news/business-35098045
As plants digest nutrients dissolved in the water might result in changes in the pH of the solution, which can then become more acid (low pH) or alkaline (high pH). It is, therefore, advisable to check constantly the values of pH and the concentration involving nutrients to avoid way too sharp fluctuations compared to optimal levels.
In addition to these parameters, the conductivity and particular electrical parameters related to the move (flow and timing) must be kept under control. It is recommended to measure the pH at least once a day, and especially right after giving nutrients that may alter the idea.
The hydroponic solutions can be bought ready-made from the manufacturers and most gardening stores: it is formulated concentrates that are dissolved in the water following the instructions on the recording label
A a good DIY solution is for you to resort to the use of some software for free (see link at the bottom of page). Even without owning large chemical knowledge, hydroponics enthusiasts may make use of these programs, created by professional chemists to prepare in their home hydroponic alternatives best suited to their plants.
