What is hydroponics and hydroponic systems?
Hydroponics is crop production with mineral nutrient solutions instead of soil containing silt and clay. Terrestrial plants can be grown with their roots in the mineral nutrient solution only or in an inert medium such as perlite, rockwool or gravel. A variety of techniques.
Perlite is a volcanic rock that has been heated glass pebbles in the foam light. Used separately or in plastic sleeves in the water. It is also used in potting soil mixtures to reduce the density soil. Perlite has similar properties and uses of vermiculite, but generally has more air and less water. If not included, which can float, If flooding and power drain is used.
Like perlite, vermiculite is another mineral until it overheated extended in the light of pebbles. Vermiculite holds more water than perlite and has a natural "lock" the assets that can draw water and nutrients in a hydroponic system passively. If too much water and not enough air around the roots of plants, it is possible to reduce gradually the capacity of water retention by mixing in increasing quantities of perlite.
Rockwool is probably the most widely used in hydroponics. Made of basalt, is heat treatment at high temperature, then turn it back together, like cotton candy. It appears in many different forms, including cubes, blocks and granulated or flock. When this medium is dry, care needs to be taken to avoid inhaling particles – such as inhalation of particles can lead to health risk. Rockwool will lead a high pH. You need to adjust the pH of the solution nutrient to counteract this. A pH level of 5.5 to 6.5 should be sufficient to create a suitable pH.
Plant physiology researchers discovered in the 1800s that plants absorb essential mineral nutrients as inorganic ions in water. Under natural conditions, soil acts as reservoir of mineral nutrients, but the soil itself is not essential for plant growth. When the mineral nutrients in soil dissolves in water, plant roots are able to absorb them. When the mineral nutrients needed are introduced into a supply plant water artificially soil is no longer necessary for the plant to grow. Almost all terrestrial plants will grow with hydroponics, but some better than others. It is also very easy to do business is often conducted by very young children with such plants as watercress. Hydroponics is also a standard technique in biology research and teaching and a popular pastime.
Hydroponics basically means working water ("Hydro", meaning "water" and "ponos" means "work"). Many civilizations have used different techniques hydroponic culture throughout history. As pointed out in Hydroponics Food Production (Fifth edition, Woodbridge Press, 1997, page 23) by Howard M. Resh: "The Hanging Gardens of Babylon, the floating gardens of the Aztecs of Mexico and China are examples of" culture hydroponics. Egyptian hieroglyphic records dating back hundreds of years before Jesus Christ describes the cultivation of plants in water. "Hydroponics is hardly a new method of growing plants. However, great strides have been made in recent years in this innovative area of agriculture.
Throughout the last century, scientists and horticulturists experimented with different methods of hydroponics. One application Possible hydroponics, who led the research was for growing fruit and vegetables in non-arable areas in the world. It is a Just because some people can not grow in the soil of your region (if there is even a floor at all). This application of hydroponics was tested during the Second World War. The non-arable islands troops stationed in the Pacific were supplied with fresh produce grown locally set up hydroponic systems. Later in the century, hydroponics joined the space program. As NASA considered the practicalities of locating a business in another plant or the moon from Earth, is based on hydroponics easily to their sustainability plans. This investigation is ongoing.
Choose the right system – if you decide to build or buy – can make or break their experience with hydroponics.
Think space, lighting, budget and time constraints before purchasing any equipment or putting on a unit to build. Think also what you want to grow, if desired, may be prolonged and recurring costs.
hydroponic systems can be "active" or "passive". Can also be "based on media" or "water culture". Active systems are based a pump for the movement of nutrients into plant roots and ventilation. Passive systems work without a pump. A breathable fabric is made nutrients to the roots or the tips of roots are suspended in a stable solution with the main part of the root ball suspended in the air.
Media Systems based communication system such as the ebb and flow (flood and drainage), the maximum power (drip) or low power are based on a culture medium to support plant and maintain the nutrient solution around their roots. Most operate on timers, alternately dipping means salts hunting water and replenish the nutrients and then drain that plants can draw from atmospheric oxygen.
cropping water generally operate without the media. Sometimes, the rock wool cubes or small quantities of gravel are used because the plants as tomatoes and cucumbers better for trucks when they begin to bear fruit and need help to stand. You can also use the wings plastic donuts, fiber cups, or plastic ties to support the plant. Some growers plant equal to a trellis.
