What Is Hydroponics?
In Latin, the word hydroponics means literally "water working."
Hydroponics is the practice of growing plants in either a bath or flow of highly oxygenated, nutrient enriched water.

In soil, biological decomposition breaks down organic matter into the basic nutrient salts that plants feed on. Water dissolves these salts and allows uptake by the roots. For a plant to receive a well balanced diet, everything in the soil must be in perfect balance. Rarely, if ever, can you find such ideal conditions in soil due to the lack of organic matter left behind on the surface, contamination and biological imbalances.

With hydroponics, water is enriched with these very same nutrient salts, creating a hydroponic nutrient solution that is perfectly balanced. And since this hydroponic nutrient solution is contained, it does not harm our environment as does runoff from fertilized soil. Additionally, very little water is lost to evaporation in a hydroponic system, owing to its application in drought stricken areas.

To support the plants in a hydroponic system, an inert soil-free medium like fiber, sand or stone, may be used to anchor the roots. These hydroponic mediums are designed to be very porous for excellent retention of air and water that's necessary for a healthy plant - roots need to breathe too!

In addition to a perfectly balanced diet, hydroponic plants have their food and water delivered directly to their roots. This way, the energy normally used to develop long roots can be redirected to growing more plant, which is a great benefit indeed! With the proper exposure to natural sunlight or supplemental grow lights, your hydroponic plants .
What Is Aeroponics?
Aeroponics is an application of hydroponics without a growing medium, although a small amount may be used to germinate the seed or root a cutting. Plant roots are suspended mid-air inside a chamber kept at a 100% humidity level and fed with a fine spray of nutrient solution. This mid-air feeding allows the roots to absorb much needed oxygen, thereby increasing metabolism and rate of growth reportedly up to 10 times of that in soil. And there is nearly no water loss due to evaporation.

The Advantages of Organic Food

You Are What You Eat

Do you really know what goes into your food? Discover the advantages of organic food on this site and see exactly what producers have been adding to your fruit and vegetables to make it less healthy than a few years ago.

advantages of organic food graphic 1In the rush to produce more and more crops to satisfy growing demand producers have had to resort to using a lethal cocktail of pesticides to control disease and insect attack.

Good news for their bank balances perhaps but not good news for your health, this is why you need to be informed of the advantages of organic food.

Did you know that if you consumed an average apple you would be eating over 30 pesticides, even after you have washed it?

The quality of food has definitely gone down since the second world war. For instance, the levels of vitamin C in today's fruit bear no resemblance to the levels found in wartime fruit.

Organic food is known to contain 50% more nutrients, minerals and vitamins than produce that has been intensively farmed.

You will have to eat more fruit nowadays to make up the deficiency, but unfortunately that means eating more chemicals, more detrimental affects on your health eating something that should be good for you!

What happens to those chemicals when the animal dies?

Digested and stored in human bodies is the answer, have you seen pictures of animals in severely cramped conditions in battery farms?

It just does not make sense to state that any animal kept in these conditions is healthy and produces high quality food.

If you are as worried as I am about the health of your family then you need to read the articles on this and seriously consider converting your family to the organic lifestyle with the organic food information you are going to learn on this site.

Trust me, once you try some organic produce and taste an apple the way it should be, and perhaps how you recall it tasting in your youth, you will never go back to mass produced fruit again.

advantages of organic food graphic 3Sure there are issues with availability and cost but with a bit of research you should be able to find local stores who stock organic produce.

Also, don't forget about your local farmer, I'm sure you will be able to find one that has seen the light and opened up a farm shop to supply local residents.

You should be able to get some very keen prices from these shops, why not take a look around and see who is offering produce in your area?

Some more startling facts now. Pesticides in food have been linked to many diseases including:

Some birth defects

Not a nice list is it? There are probably others but if you think about it, how can it be okay for you to eat chemicals and not expect some form of reaction in your body. Our bodies are delicately balanced wonderful machines. Any form of foreign chemical is bound to cause irritation at the least.

Please take advantage of the organic food articles and information on this site and do consider taking a closer look at what you are eating. It's for your health after all!
