Hydroponic Systems

Hydroponics is a type of horticulture and a subset of hydroculture, which is a method of growing plants, usually crops, without soil, by using mineral nutrient solutions in an aqueous solvent. Terrestrial plants may be grown with only their roots exposed to the nutritious liquid, or, in addition, the roots may be physically supported by an inert medium such as perlite, gravel, or other substrates. Despite inert media, roots can cause changes of the rhizosphere pH and root exudates can affect the rhizosphere biology.

The nutrients used in hydroponic systems can come from many different sources, including (but not limited to) fish excrement, duck manure, purchased chemical fertilizers, or artificial nutrient solutions.

Plants commonly grown hydroponically, on inert media, include tomatoes, peppers, cucumbers, strawberries, lettuces, marijuana, and model plants like Arabidopsis thaliana.

Hydroponics offers many advantages, one of them being a decrease in water usage for agriculture. To grow 1 kilogram (2.2 lb) of tomatoes using intensive farming methods requires 400 liters (88 imp gal; 110 U.S. gal) of water; using hydroponics, 70 liters (15 imp gal; 18 U.S. gal); and only 20 liters (4.4 imp gal; 5.3 U.S. gal) using aeroponics. Since it takes much less water to grow produce, it could be possible in the future for providers in harsh environments with little accessible water to grow their own food.

There are two main variations for each medium: sub-irrigation and top irrigation. For all techniques, most hydroponic reservoirs are now built of plastic, but other materials have been used including concrete, glass, metal, vegetable solids, and wood. The containers should exclude light to prevent algae and fungal growth in the nutrient solution.

Types Of Hydroponic Systems For Growing Plants Indoors

There are many different types of hydroponic systems that can be used to grow your plants. This article is intended to help you choose the best hydroponic system for your growing needs. All hydroponic systems have pros and cons, so be sure to do your research before choosing the best hydroponic system for you. Here is a sample of the most popular hydroponic systems for home use, along with their pros and cons.

The best way to learn about hydroponic systems for home use is to visit a hydroponic store or search the internet to purchase some literature on hydroponic systems. A good example of hydroponic system literature is a bookshelf filled with books about hydroponic systems. Video walk throughs for all systems. This should give you a good idea of what each hydroponic systems is capable of.

The best hydroponic system ideas are based around producing nutrient rich soil that is easily maintained by your growing solution. The nutrient solution can be made by mixing in well rotted organic materials like bark, coffee grinds, sea salt, or other natural, organic sources of nutrients. Your nutrient solution should contain high-viscosity water or you may have to purchase water beads to make the solution more dense.

A nutrient film is a thin membrane applied over the growing medium in your hydroponic system and provides a layer of protection for the roots. It also helps to maintain the correct Ph (how acidic or alkaline your medium is) of your plants' root zone. The nutrient film is applied to the surface of the growing medium after you have poured the nutrient solution on the bedding material. It is an important step to growing healthy plants because it prevents water from seeping below the leaf level and being wasted.

There are three main types of hydroponic systems: aeroponic systems, drip systems, and gravity flow systems. Aeroponic systems require a collection bucket, a media bag, and some air stones to provide the growing medium for the plants. You can use hydroponic bags, air stones, or other media that can provide your plants with a sterile environment similar to what they would find in their natural habitat. They don't require any special filtration, triturating or aeration equipment.

An aeroponic system uses a water culture pump and a collection container filled with a nutrient solution. A water culture pump is a handy tool to use because it is simple to use and inexpensive. The pump fills the basket with the nutrient solution and air stones push the water down the stem of the plant. You can move the pump closer to the root zone of the plants or place it on the outside of the grow bed. Because the pump and container acts as an aerator, air circulation is enhanced and root growth is promoted. This type of system can be used in small growing environments because it does not require any sort of outside aeration.

A gravity flow system pumps water down through a system of pipes that are placed below the grow beds. The pump fills the basket with water and leaves it to settle at the bottom of the tank. The pump re-circulates the nutrient solution in the nutrient solution tank to provide oxygen to the roots. The only requirement is that the pump should be turned off when it is not in use. If you want to use a manual pump, make sure it has a manual switch to turn it off.

All hydroponic systems work on the same principal; however, the materials used differ from system to system. If you are new to hydroponic gardening then you will want to start with a starter hydroponic kit. This type of kit will get you going in the right direction. Starter kits usually contain hydroponic soil and nutrients for planting. You will want to read up on hydroponic gardening before making your purchase so you do not waste time or money.
