Gardening And Hydroponics – The Perfect Answer.
There is no doubt that the average horticulturalist and gardening is used to getting dirty. After all, they are constantly rooting around in soil, applying pesticides and fertilizers. They often plant, divide, and plant again. They do this so they can see and eat the nutritious and lovely plants they've grown. What if these values could be gained without ever having to come into contact with soil of any kind?
Hydroponics is the practice and science of growing healthy plants without the use of soil. Instead, water is the medium that used most often. Certainly there are definitions that are more accurate, technically speaking, but for the teacher, hobbyist and home gardener, this is what hydroponic gardening is about.
Many people wonder how this is even possible since they know that plants require soil for nutrition, support, heat, water, and all the other factors that are needed fro growth and reproduction. While that is what most people understand about gardening, its not necessarily true. Plants absolutely require water, but they don't have to get it from soil even though that is the most common method. In nature, there are plants that grow well in gravel, sand or underneath or on top of a body of water.
Plants require a specific amount of energy, whether it's in the form of heat from their surroundings or sunlight. However, sunlight is not the only to get this warmth. Direct sunlight will work on the leaves, exactly as it does on the soil. Allowing the top of the plant to be exposed to sunlight, supported by string from the top of the container, will allow the vital process of photosynthesis to occur. However, with almost anything in botany, there are some exceptions. Some plants are able to survive as well as reproduce with absolutely no light, but they will still require some form of energy to initiate biochemical reactions.
The majority of plants that interest the hobbyist or home gardener will require some physical support. One of the most common ways to achieve this support is planting them in soil. When this is done the stems become wind resistant and the roots will spread. These plants wouldn't be in existence is they hadn't evolved in this manner.
However, there artificial ways to support these plants that work very well. Some of these methods include using string or ice cream sticks that have been glued to the top of the container.
Without a doubt, nutrients are one of the most critical elements for a plant. For good plant growth, a host of trace elements like iron, copper, and zinc are needed as will as phosphorous, potassium, and nitrogen. The normal way that plants get these nutrients is to absorb them from soil, but there are a number of different ways to deliver nutrients to a plant that are often used in hydroponic gardening.
Immersing the roots in a container of water that is periodically fed a liquid nutrient solution is one popular technique. There are others. Some hydroponically grown plants are housed in an enclosure that retains moisture well. The roots are then sprayed often with a mister that douses the roots with a nutrient solution. This crosses into the gray area known as aeroponics.
Hydroponic gardening methods can be used to grow a number of plants like lettuce, tomatoes, strawberries, and other plants that are not fruits or vegetables, like orchids. Hydroponics can be used to grow a long list of plants. There are thousands of plant species that thrive without the use of soil as long as they are properly cared for. The effort can be fun as well as instructive. Hydroponics can be use to grow nutritious and beautiful plants, without the drawbacks of using soil.
