Hydroponics can be described as the art of gardening without soil. Hydroponics means “working water” in Latin. It is the art of cultivating plants without soil. The careful regime of hydroponics can make plants thrive from jalapenos, watermelons and orchids. Hydroponic gardens need a small amount of space and 90 percent less water than conventional farming. They also produce beautiful fruits, flowers, and vegetables in a fraction of the time.
Though the technology sounds modern Hydroponics’ history dates back to the famed Hanging Gardens of Babylon, one of the Seven Wonders of the Ancient World. The Euphrates River was channelized into channels that cascaded through the extravagant gardens’ walls. Marco Polo, a 13-year-old writer from Italy, wrote about floating gardens in China. The concept of hydroponics wasn’t only a fad from the past. NASA developed aeroponic beans seedlings to be used in space agriculture. Hydroponics is a long-standing and innovative method of conserve water and increase crop growth.
What exactly is hydroponics?
Hydroponics is the practice of cultivating plants that do not require soil. Hydroponic plants include herbs, vegetables and even flowers. The media includes inert growing media which is nourished with oxygen, nutrients, and water. This system promotes faster growth, higher yields, and higher quality. The plants are grown in soil. Their roots continuously search for nutrients to sustain them. The plant does not have to use any energy to support itself when its root system is exposed to nutrients and water. The energy that the roots expended in to acquire food and water could be channeled into the plant’s maturation. Foliage growth is encouraged as is the flowering and fruiting of flowers.
Photosynthesis is how plants live. The green pigment chlorophyll found on the leaves of plants captures sunlight. The light’s energy is used to disintegrate water molecules they’ve taken in from their roots. The hydrogen molecules combine with carbon dioxide to create carbohydrates that plants utilize to nourish themselves. This allows oxygen to be released into the atmosphere. This is a crucial factor in preserving our planet’s ability to sustain itself. To produce photosynthetic energy plants don’t require soil. They require soil to supply the water and nutrients. These nutrients are added directly into the root systems of plants by flooding, misting or immersion after they are dissolving in water. Hydroponic innovations have proven the direct application of nutrient-rich water can be an effective and flexible method of growth over traditional irrigation.
What is the process behind hydroponics?
The hydroponic system allows for fine control of the conditions, including temperature and PH balance. It also maximizes the amount of nutrients that are available to. The concept of hydroponics is based upon a simple principle: Give plants what they need and when they require it. Hydroponics provides customized nutrition specific to each plant. They allow you to control exactly how much light the plants get and for the length of time. The pH levels can be tracked and modified. The environmental conditions can be completely managed and adjusted to accelerate the growth of plants.
A variety of risk factors can be controlled by you. The plants that are that are grown in fields and gardens are exposed to a variety of factors that can negatively affect their health and development. Diseases of plants can be transmitted by soil fungus. Wild animals like rabbits may take your garden’s ripe vegetables. Pests that eat crops such as locusts can be capable of destroying crops within a couple of hours. Hydroponic systems end the unpredictability of cultivating plants outside and in the earth. Seedlings will mature much quicker if they’re not subject to the soil’s mechanical resistance. Hydroponics permits the creation of healthier and higher-quality fruits, vegetables, and flowers by eliminating pesticides. With no obstructions, plants are able to expand rapidly and vigorously.
What are the main components of a hydroponic plant?
A few key components are necessary to ensure a successful hydroponic system.
Inert media, which help anchor the root structure and help support the weight of the plant, is often used for hydroponic plants. While growing media is an alternative to soil, it doesn’t give the plant any nutrients. Instead, this porous medium retains nutrients from the solution and delivers them to the plant. A lot of growing media are pH neutral, which means they will not alter the balance of your nutrient solutions. There are many media options available. The particular hydroponic system and plant will determine which media is best suited to your requirements. You can find hydroponic media in your local nursery or gardening retailer, and on the internet.
Pumps and stones for air
Plants are susceptible to drowning when they are immersed in water. Airstones create tiny bubbles containing dissolved oxygen within your nutrient reservoir. The bubbles disperse the nutrients that are dissolved evenly across the solution. Air stones do not produce oxygen by themselves. These stones need to be linked to an external pump with transparent food-grade plastic tubing. The opacity will stop algae from growing. Air pumps and air stones are popular aquarium components and are easily available in pet stores.
Net pots can be used to grow hydroponic plants in mesh planters. The latticed materials allow roots to access the sides and bottom of the pot. They also provide oxygen and nutrients. Net pots also drain more than traditional clay and plastic pots.
What are the six kinds of hydroponic system are available?
There are hundreds of hydroponic techniques, however each one is an adaptation or combination of six basic hydroponic systems.
1. Systems for deep water culture
Deep water cultivation hydroponics is a simple process of putting plants in aerated drinking water. DWC systems, also called deep water culture systems are among the most popular methods of hydroponics. A DWC system hangs net pots that hold plants over a deep reservoir of oxygen-rich nutrient solution. The roots of the plant are submerged in the solution, providing it with continuous access to nutrients, water, and oxygen. Some people consider deep water cultivation to be the purest form of hydroponics.
Because the root system is suspended in water all the time the proper oxygenation of water is vital to the plant’s survival. If there is not enough oxygen supplied to the plant’s roots, the plant will drown in the water. Add an air stone connected to an air pump near the base of the reservoir to supply oxygenation throughout the system. The nutrient solution will also circulate due to the bubbles made by the air stone.
A deep water culture system can be constructed at home or in the classroom with the least amount of expense. To house the net pots it is possible to make use of an aquarium that is old or a clean buckets to store the solution. The plants that are part of DWC systems should have their roots submerged in the solution. The plant or stem should be underwater. Even the roots should be left about an inch and half above the waterline. They will not dry out because the air stone bubbles from the surface will splash on the roots.
What are the benefits of deep-water culture systems?
- Low maintenance: After an DWC system is in place, there’s very little maintenance required. It is only necessary to replenish the nutrient solution when needed. Also, ensure that your pump is supplying oxygen to the airstone. It is generally not required to replenish the nutrient solution every two weeks. But, this can depend on the dimensions of the plants.
- DIY appeal: Unlike many hydroponic systems, deep water cultivation systems can be constructed cheaply and easily at home, with a short trip to the local pet store or nursery to pick up the air pump and nutrients.
What are the drawbacks of deep-water culture systems?
- Restrictions: Deep-water culture systems are great at cultivating herbs and lettuce, however they struggle to produce larger and slower-growing plants. DWC systems do not perform well with flowers. But, you can still cultivate bell peppers, tomatoes and squash in a DWC with a effort.
- Temperature control It is essential that your water solution doesn’t exceed 68°F, and never fall below 60°F. DWC systems have water that does not circulate and it is therefore more difficult to regulate the temperature.
2. Wick systems
In a wick-based system, plants are tucked into growing media on a tray that sits on top of the reservoir. This reservoir holds water with minerals that are dissolved. The wicks move through the reservoir until they reach the tray for growing. The flow of water and nutrients flows up the wick and fill the growing medium within the root systems of the plants. These wicks can also be constructed from string, rope or even felt. Wick systems are by far the simplest type of hydroponics. Passive hydroponics is Wick systems. They don’t need pumps or mechanical parts to work. They are perfect for locations where electricity is scarce or not reliable.
The capillary action process is what makes the wick systems function. Wicks absorb and transfers the nutrients from the water it’s immersed in. Wick system hydroponics only work when it is accompanied by a growing medium which can facilitate nutrient and water transference. Coco coir (fibers from the outer husks of coconuts) are excellent at retaining moisture as well as the additional benefit of being pH neutral. Perlite is pH neutral, and extremely porous, which makes it perfect for wicking systems. Vermiculite is extremely porous structure and a high capacity for cation exchange. This means it is able to store nutrients for later uses. The three media listed above are ideal for systems of hydroponics that use wicks.
Wick systems are quite slow compared to other hydroponic systems, which limits what you can to grow using them. For every plant you place in the growing tray, ensure that at the very least one wick is running out of the reservoir. These wicks must be placed near the roots of the plant. Although they are able to function with aeration many people prefer to add an airstone and pump to the reservoir of the wick. This will provide extra oxygen to the plant.
What are the benefits of using a wicking system for your company?
- Simple: A wick system can be installed by anyone, and doesn’t require a lot of attention once it is running. Your plants will never be dry because the wicks provide water to them all the time. Additionally, lettuce-loving plants thrive in the wick system, bringing a great return on your hands-free investment
- Space-efficient:Wick system are very discreet and can be mounted anyplace. It is a perfect system for teachers, novices or anyone interested in exploring hydroponics.
What are the disadvantages of wick systems?
- LimitationsLettuce and other herbs such as basil, rosemary and mint are fast-growing plants that don’t need much water. Due to their need for nutrients and hydration tomatoes are not able to thrive in wick systems. Others plants aren’t able to thrive in an environment that is always humid. Root vegetables like turnips and carrots will not succeed in a wick system.
- Susceptible to rot:A hydroponic wick system is always damp and humid. This creates the risk that fungal outbreaks and rot could develop in the organic growing media and on the roots of your plants.
3. Nutrient film technique systems
Nutrient film technology (NFT) techniques suspend plants above an endless flow of nutrient solution that washes over the ends of the plant’s root systems. The channels that hold plants are tilted so water can run down the length the tray before flowing to the reservoir beneath. The reservoir then gets aerated by an airstone. Submersible pumps then move the nutrient-rich water from the reservoir to the top of the channel. The nutrient film technique is a recirculating hydroponics system.
In contrast to deep water-based hydroponics the roots of the plants within an NFT system are not immersed in water. Instead, the stream (or film) runs over the roots’ ends. The roots’ tips will trap moisture in the soil while the exposed root systems are given ample oxygen. The bottoms and sides of the channels are sanded to allow the water to pass easily over the root tips. This stops water from logging up or clogging the roots.
Even though nutrient films technology systems continuously recycle water, it’s recommended to drain the reservoir regularly and replenish the nutrients solution every other week. This will ensure that your plants receive adequate nutrition. NFT channels must be designed with an angle that is gradual. The slope must not be steep enough as the water can swell down and cause damage to the plants. Too much water can make the channel overflow, and plants may drown. NFT hydroponics are able to support a variety of plants in a single channel, and they can be easily mass-produced. The best nutrient film technology systems are for light plants like lettuce, spinach mustard greens, kale. To support heavier fruiting plants like cucumbers and tomatoes, trellises will be required.
What are the benefits of a nutrient-film technique?
- Low consumption NFT hydroponics do not require large amounts of water and nutrients to function. Because the water flows continuously and salts are not able to accumulate over the root system. Nutrient film technology doesn’t need growing media. This saves you the expense of purchasing media as well as the hassle of changing it.
- Modular design: Film technique systems that are nutrient-based are perfect for large-scale and commercial endeavors. It is easy to increase the size of your greenhouse once you’ve got one channel working. You can create multiple channels supporting different plants. Each channel needs its own reservoir. This ensures that the operation will continue throughout the entire process regardless of the fact that the pump fails or there is a spread of disease.
What are the benefits of using a nutrient film technique?
- Plants can die when the pump isn’t functioning correctly and the channel ceases to circulate the nutrients, Without water supply, your entire crop may die within hours. Maintaining an NFT hydroponic system requires vigilance. You’ll need to pay attention to the operation of every pump.
- Overcrowding can lead to obstruction of the channel when roots are growing too quickly or are too closely spaced. Roots can block water flow, causing your plants to starve. This is especially true for plants in the lowest. If the plants near the bottom ever seem to be underperforming compared to the rest of the channel Consider removing certain plants or switching to smaller units.
4. Ebb and flow systems
By flooding the growing area below using a nutrient-rich solution Ebb and flow hydroponics works. The timer is part of the submersible pump located in the reservoir. The pump is able to fill the grow beds with nutrients and water when the timer is turned on. When the timer stops it is a matter of gravity slowly draining the water from the growing bed before flushing it back into the reservoir. The overflow tube makes sure that the flooding doesn’t exceed a set amount and can result in damage to the fruit or stalks. Unlike the previous systems mentioned that the plants within an flow and ebb system are not constantly being exposed to water. When the growing bed is flooded and the plants ingest the nutrient solution through their root systems. As the water evaporates the roots dry up. The dry roots then oxygenate in the interval before the next flood. The size of your grow beds and the size your plants will determine how long it takes between floods.
One of the most popular hydroponic gardening methods is the ebb and flow method (also called flood and drain). The plants benefit from an abundance of oxygen and nutrition that stimulates rapid and robust growth. The ebb-and-flow system is flexible and easily adjustable. It can also be equipped with a variety of net pots and various fruits and vegetables. The ebb-and flow system is the most flexible hydroponic system. It lets you play around with different plants and media.
Ebb and flow systems can accommodate almost all types of vegetation. The main limitation is the size and depth your plant tray. Root vegetables need more space than lettuce and strawberries. Popular ebb-flow crops include peas, tomatoes and beans as well as cucumbers, carrots and peppers. You can even attach trellises directly at the beds for growing. “Grow rocks” and expanded clay pebbles (hydroton) are some of the most popular growing media used in ebb and flow hydroponics. These are easy to wash, reuseable, and lightweight. This is a crucial feature in flow and ebb systems.
What are the advantages of an ebb and flow system?
- Flexibility: An ebb flow system allows you to grow plants that are larger than other systems for hydroponics. The use of ebb and flow hydroponics are a great way to cultivate flowers, vegetables and even fruits. You will get a bountiful harvest if you take care to provide your plants with the proper size growing bed, nutrients, and other necessary things.
- DIY appeal: There are many ways to create your own ebb-flow system at the home. A trip to the hardware store or pet store will provide you with all the supplies needed to build an ebb-flow setup. Although ebb systems are more expensive than DIY methods such as wick or deep-water cultivation, they offer a much wider variety of plant life.
What are the drawbacks of an Ebb-flow system?
- Pump failure: As with any other hydroponic setup reliant on pumps, in the event that the pump ceases to work and your plants die, they will. You do have to monitor your flow and ebb system to ensure that the system’s performance isn’t harming the health of your plants. Your plants won’t receive enough nutrients and water if the water rushes into and out of the system too fast.
- Disease and rot:Sanitation and maintenance are vital to the ebb and flow system. Rot and root diseases can develop if the bed doesn’t drain well. A dirty ebb-flow system could draw in insects and cause mold to grow. Your crops will suffer when you fail to keep your system clean. Certain plants aren’t able to respond to the rapid changes in pH caused by extreme flooding and draining.
5. Drip systems
Hydroponic drip systems provide a nutrients-rich and aerated solution from a reservoir via the tube network system to individual plants. This solution is slowly dripped into the root system of each plant. It helps keep them moist and well-nourished. Drip systems are popular techniques for hydroponics, particularly for commercial cultivators. Drip systems may be used to water individual plants or for large-scale irrigation.
There are two types of drip hydroponics systems that are recovery as well as non-recovery. In systems that are recovering, which is more popular with smaller, at-home growers, excess water is drained from the grow bed back into the reservoir, to be recirculated in the following drip cycle. The excess water from non-recovery system drains from the media and goes to the waste. This method is much more popular with commercial growers. The non-recovery drips may seem inefficient but large-scale growers are extremely conservative about water consumption. These drip systems are created to supply just the appropriate amount of water to keep the growing medium around the plant moistened. Non-recovery drips use elaborate timers and feeding programs to reduce the amount of waste.
Plants grown in a recovery drip plant system will need to be aware of variations in pH of the nutrient solution. This is the case for any system with wastewater recirculating into the reservoir. Plants will deplete the nutrient content of the solution as well as altering the pH balance, which means the grower will need to monitor and adjust the solution reservoir more than they would require in a non-recovery system. Also, growing media can be excessively high in nutrients and require frequent changes.
What are the advantages of a drip system to your company?
- There are a variety of alternatives to grow plant species: Drip systems can produce bigger plants than other hydroponic systems. Commercial growers are enthralled by this system. A properly-sized drip system can support melons, squashes, onions, and zucchinis. Drip systems can hold greater amounts of materials than other types of systems. This allows them to support the larger root system of the plants. Drip systems work best when used with slow-draining media such as coco coir or rockwool.
- Scale: Drip systems are able to easily accommodate large-scale hydroponics. Growers can also add more plants by connecting new tubing to the reservoir. The drip system that is in place can be altered to accommodate the new crop. Additional reservoirs may be added to accommodate different timers that meet the requirements of the plants. This is another factor that makes drip systems a popular choice for commercial hydroponics
What are the downsides to drip systems?
- MaintenanceIf your house is not a recovery system, it’ll require some attention. It is essential to keep track of the pH and nutrient levels of the solution. It is essential to remove and replace the tank when required. It’s possible for recovery systems lines to become clogged from dirt or plant matter. Therefore, you need to clean and flush the lines regularly.
- ComplexityDrip systems are easy to make complex and intricate. This is less important for professional hydroponics. However, it’s not the ideal method for hydroponics at home. Ebb and flow are simpler systems that are suitable for hydroponics at home.
Aeroponics systems suspend the roots of plants within the air and then expose the roots to a mist of nutrients. Aeroponics systems utilize enclosed structures, such as towers or cubes, to hold many plants at once. A reservoir is utilized to store nutrients and water. The solution is then pumped into an engine that distributes it as fine mist. The mist typically is released from the tower and can be observed cascading through the chamber. Aeroponics can continuously mist the roots of the plant, similar to NFT systems, which expose the roots to the nutrients film at all times. Some are more of an ebb-and-flow system spraying the root with mist on a regular basis. Aeroponics doesn’t require any substrate media to survive. The constant exposure of the roots to the air allows them to absorb oxygen and grow at a a faster rate.
Aeroponics systems require less water than any other type of hydroponics. In fact, it takes 95% less water to grow a crop aeroponically than in an irrigated field. Vertical gardens Because their vertical design occupies a small space, it allows several towers to be placed in the same space. Aeroponics produces high yields and can be achieved even in confined areas. Aeroponic plants develop faster since they’re exposed to greater oxygen than other hydroponically-grown varieties.
Aeroponics permits harvesting all year round. Aeroponics provides a wonderful environment for vine plants, nightshades tomatoes, bell peppers, eggplants, and other nightshades. All other plants such as baby greens (lettuce) as well as watermelons (watermelon), strawberries, and ginger also thrive in an aeroponic atmosphere. The fruiting trees can’t be grown aeroponically because they’re too large and heavy. Also, underground plants with large root systems, like carrots or potatoes, can’t be planted.
