An Alternative Solution For Producing Crops Is Hydroponics

Hydroponics is a method that replaces soil with a combination of water and various minerals and nutrients. The word hydroponics comes from Greece and means “working water”, in fact we replace the soil with a water rich in all the elements essential for the plants to grow. Hydroponics has a very long history, it is well known that both Aztecs and Babylonians used it to grow plants without soil, even if they obtained the nutrients solution in a different way than we do. The chemical combinations we use today in hydroponics were discovered as late as the 19th century.

Advantages and Disadvantages

If you remove a plant from soil it will eventually die, but if we pack the plants according to the hydroponics techniques the grown vegetables can be sold while still having their roots dipped in nutrients. The resulting products will be fresh for a much longer period of time. Using hydroponics environment will assure that the plants receive just as much water as necessary, also you won’t need to dispose the solid soil. Hydroponics could be the best solution for growing crops in hostile environments where proper soil can’t be found, for example think about Antarctica or any other hostile place.

Furthermore, hydroponics is an effective way of teaching students everything about plants growth since the root is so perfectly visible in the most natural way. Another advantage for the use of hydroponics is the fact that all diseases related to soil are eliminated and much fewer pesticides are used. Also a minimal level of water is needed compared to the irrigation system. Hydroponics is in many cases much cheaper than traditional methods, for example when growing strawberries we obtain a new crop 20% cheaper. Statistically these plants are less vulnerable to root problems, and fertilization is done more easily. The best thing is that a system using hydroponics is very cheap and doesn’t require any qualifications.

Is hydroponics that good?

It is true that hydroponics benefits and use have been exaggerated and considered a miracle that would change the face of agriculture all over the world. The fact is that using hydroponics won’t produce you greater crops than good quality soil would. Also it is not a sure thing that hydroponics techniques lead to obtaining better and tastier fruits that classical methods do. Hydroponics is a good solution in remote regions with poor soil, where agriculture doesn’t stand the smallest chance. In such cases, it comes as the only viable solution to grow green plants.

Hydroponics Gardening - An Introduction To Hydroponics Gardening For Beginners (Part 11) What Is pH?

Tip! Hardness of water can be measured in parts per million by using a total alkalinity test kit. These cheap simple test kits are available from your local hydroponics retailer and are quite accurate enough for the purpose.

pH Is The Most Important Factor In Aquaculture.

What Is pH?

pH is the term used to assess the acidity or alkalinity of a solution. This acidity or alkalinity is determined by measuring the concentration of Hydrogen ions in the solution. This normally falls between 10 0 and 10-14 gram-equivalents per litre. In order to simplify this, a scale of values between 0 and 14 has been adopted.

This pH scale is a measurement of how strongly the electrical charges hold the atoms and molecules of substances within the solution together. The higher the concentration of positively charged ions, the lower the value is on the scale and the higher the concentration of negatively charged ions the greater the pH value.

Hydrogen (H+) has a positive charge while the hydroxides (OH-) have a negative charge. Pure water has a value of 7.0 so it is easy to see that water must be H-OH or more commonly H2O.

Tip! The equipment to grow plants using a hydroponics system is easy to obtain and can be easily picked up at a local store or over the internet. They are reasonably priced and easy to use.

The decimal points on the scale are very important because each whole number is approximately 10 times greater (or less) than the next whole number. So pH 2.0 is 1000 times stronger than pH5. The greater the concentration of Hydrogen ions in the solution the more acidic it is said to be and the lower its pH on the scale. The greater the number of hydroxide ions the greater the alkalinity (or basicity) it is said to have and the higher its pH.

If we look at the structure of the pH scale, we can see that it goes from 0 (very strong acid) to 7 (neutral) and then to 14.0(very strong Base or Alkali). If we mix an acidic solution with an alkaline one, providing that the positions on the scale are equidistant from the neutral value of 7.0, we will end up with a neutral solution. This is because the positive charges will be cancelled out by the negative ones. If however we use differing positions on the scale, then the resulting imbalance will give us a solution with either acidic or basic properties depending on which side had the greater distance from the neutral value.

Tip! Water Culture, Aquaculture, or Nutriculture. This is a Hydroponics system in which the plant roots are immersed in water containing a complex mixture of dissolved nutrients.

But Why Is This So Important?

All of the chemicals in the solution have differing electrical charges because each of them is made up of different combinations of elements and ionic values. As they are all competing for the exchange of charged particles, a huge electrical battle is constantly raging within the solution. This constant exchange of positive and negative charges surrounds the plant’s root system and it is this that allows it to absorb the vital nutrients needed for its growth.

Essential Tips About Your Refrigerator Water Filter

Refrigerators preserves our food fresh and crisp until we are ready to consume it as well as it provides us with ice and cold water which is essential in the summer but not only. The water that flows freely from the tap is contaminated with different types of bacteria, chemicals, minerals and pesticides due to which reason all refrigerators that produce ice and provide cold water will also have a refrigerator water filter system.
The Life Span Of the Refrigerator Water Filter
The life span of your refrigerator water filter depends mostly on how much it is used and in the amount of contaminants found in the water. Most refrigerators that have these features will also have guide lines on when you should change the refrigerator water filter, which should not be more then six months at a time even if the use is minimal.
Most refrigerator water filters use the charcoal systems because they are the most powerful and guarantee to remove approximately 95% of the contaminants found in water at all time; the filter wears out in approximately six months with the amount o bacteria present in the water and can leak if not replaced.
