The Basics of Hydroponics

hydroponics basics

Hydroponics is crop production with mineral nutrient Solutions instead of soil containing silt and clay. Terrestrial plants may be grown with their roots in the mineral nutrient solution only or in an inert medium like perlite, gravel or rock. A variety of techniques exist.

Perlite is a volcanic rock that has been superheated into very lightweight expanded glass pebbles. It is used in bulk or in plastic sleeves immersed in water. It is also used in potting soil mixtures to reduce the density of the soil. Perlite has similar properties and uses to vermiculite but generally holds more air and less water. If it is, it can float if flood and drain feeding is used.

Like perlite, vermiculite is another mineral that has been superheated until it has expanded into light pebbles. Vermiculite holds more water than perlite and has a wicking “natural” property that can draw water and nutrients in a hydroponic system passive. If too much water and not enough air around plant roots, it is possible to gradually reduce the medium water holding capacity by mixing in increasing quantities of perlite.

Rockwool is probably the medium most widely used in hydroponics. Made from basalt, it is a heat treatment at high temperatures then spun back to candy floss. It comes in many different forms, including cubes, blocks, slabs and granulated or flock. When this medium is dry, care must be taken to avoid inhaling particles – the inhalation of these May particles pose a risk to health. Rockwool will cause a pH level higher. You need to adjust the pH of the nutrient solution to counteract this. A pH level of 5.5-6.5 should suffice to create a suitable pH.

Plant physiology researchers discovered in the 1800s that plants absorb nutrients essential minerals as inorganic ions in water. Under natural conditions, soil acts as a reservoir of elements mineral nutrients, but the soil itself is not essential to plant growth. When the minerals in the soil dissolve in water, plant roots are able to absorb them. When the mineral elements needed are introduced in the water of an artificial plant, the ground is no longer necessary for the plant to grow. Almost all terrestrial plants will grow with hydroponics, but some will pull better than others. It is also very easy to do, activity is often undertaken 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 is work mainly water ( “hydro” means “water” and “ponos” means “work”). Many civilizations have used techniques of hydroponics throughout history. As noted in Hydroponic 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 those of China are examples of” Hydroponics. Hieroglyphic Egyptian records dating back several centuries BC describe the growing of plants in water. “Hydroponics is hardly a new method of growing plants. However, great strides have been made over the years in this innovative area of agriculture.

Throughout the last century, scientists and horticulturists experimented with different methods of hydroponics. One of the possible applications of hydroponics that drove research was for growing fresh produce in non-arable areas of the world. It’s a simple fact that some people can not grow in soil in their area (if There are even no soil at all). This application of hydroponics was tested during the Second World War. The troops stationed on islands non-arable in the Pacific were supplied with fresh fruit and vegetables grown in systems in place locally for hydroponics. Later in the century, hydroponics was integrated into the space program. As NASA considered the practicalities of locating a company to another plant or the Moon from Earth, hydroponics easily integrate into their sustainable development plans. This research is ongoing.

Choose the right system – If you decide to build or buy – can make or break your experience of hydroponic gardening.

Scrutinize your available space, lighting, budget and time constraints before purchasing any equipment or installation on a drive to build yourself. Consider also that you want to grow, if you want to expand in May, and recurring costs.

Hydroponics can be “active” or “passive.” They can also be “based on media” or “water culture.” Active systems rely on a pump for flow nutrients to plant roots and provide ventilation. Passive systems work without a pump. A wick material draws elements with the roots or the roots are suspended in a stationary solution with the main part of the root ball suspended in air.

Media-based systems, such as ebb-and-flow (flood and drain), top-feed (drip), or “bottom-up power systems rely on a culture medium to support Plants and hold nutrient solution around their roots. Most operate on timers, alternately wetting medium and wash the salt and reconstitute the elements nutrients, then drain if the plants can draw from atmospheric oxygen.

Cropping systems of water generally operate without media. Sometimes, cubes of rock wool or small quantities of gravel are used because plants like tomatoes and cucumbers Heavy Get up when they start to bear fruit and need assistance to stand. You can also use plastic parts, foam rings, cups fiber or plastic necklaces to support plants. Some growers tie the plants to a trellis.
