What is hydroponics?
The answer to What is Hydroponics and how to use use them is here. Some plants require so much water that if they were grown in the ground. They would quickly become waterlogged and would either drown or their roots would rot.
Soil also contains many nutrients essential to the health of plants. But which are washed away with water.
Hydroponics solves both of these problems by growing plants without soil, using only water and fertilizer held in reservoirs below the plants’ roots instead of in the soil around them. Here you will understand the hydroponic gardening meaning and hydroponic installation.
Hydroponics means working water or working water system, which involves growing plants in an artificial environment that includes mineral solutions in water, without soil.
It can be used to grow almost any plant, from small fruit and vegetables to large trees.
To understand the concept of hydroponics, think about how plants grow naturally in forests or fields with rich natural nutrients provided by topsoil, air and sunlight.
Here we provide answers to all your questions like how to make nutrients for hydroponics.
Advantages of Growing Plants Hydroponically
There are many advantages of growing plants in a hydroponics light.
- Hydroponic systems typically cost less to install and maintain than conventional soil-based systems. And yield more fruits and vegetables.
- It can be hard to determine exactly how much food you will produce Because it depends on what you plant and how much your grow lights can sustain.
- If you get any results that seem particularly low or high. Make sure you keep an eye on them. Sometimes it takes time for plants to get used to their new environment.
- One major advantage of the hydroponic floating systems is that they use less water than regular garden methods. Which makes them a good choice for those who have a limited water supply. Or those who want to conserve as much as possible.
- With hydroponic farming, there are almost no limitations to which types of plants can be grown.
- As long as a plant has access to nutrients, it will grow. Because of that, you have more control over what you’re growing.
- It’s not uncommon for farmers to grow multiple crops during a single growing season. Because they have so much flexibility with which plants they can grow at one time.
Disadvantages of Hydroponic Gardening
Since it’s not as common as other types of gardening. Some people aren’t familiar with some of its drawbacks. However, there are a few things you should know about its disadvantages.
- The biggest issue people have with hydroponic gardening and hydroponics setup is that it’s more complex than other types of garden set-ups.
- Not only does your garden need a larger amount of space and sunlight. But your plants will also require different fertilizers and nutrients to thrive. Something that may prove problematic for beginners just learning how to grow their own food at home.
- Another disadvantage is that while growing your plants in water, the soil isn’t part of the equation.
- If you use organic fertilizers or natural solutions instead of chemicals to feed your plants. They can still develop nutritional deficiencies or pests despite being grown in water.
- This means that hydroponics isn’t always healthier for your family since you may end up treating them anyway.
- Hydroponic gardening works by feeding plants directly through their roots in a nutrient solution.
- If any of that solution leaks out into soil or open air. It can quickly be absorbed and used by surrounding vegetation.
- Since your goal in growing food with a hydroponic float system is to have a high yield with minimal waste, any lost nutrients are a waste of money.
Types of Hydroponic Systems
There are two main types of hydroponic systems:
Deep Water Culture (DWC)
Nutrient film technique (NFT).
What is deep water culture (DWC) Hydroponic gardening
- DWC involves flooding a large volume of growing media with nutrient-rich water. That’s then pumped up to drippers above your plants. The water that doesn’t drip back down goes back into your reservoir.
- Deepwater Culture (DWC) systems are composed of Styrofoam floating baskets in the hydroponic tray. Airtight containers with holes in their bottoms float on top of nutrient-rich water.
- Deepwater Culture (DWC) is a highly effective form of gardening which requires little maintenance. Saves on time and money, and yields some truly impressive results.
What are the benefits of deep water culture (DWC) Hydroponic gardening
- Deepwater Culture (DWC) involves suspending grow media such as clay pellets, Rockwool, or lava rock over a deep reservoir of DWC hydroponics nutrients solution.
- Air pump and airline tubing bring oxygen to and from plant roots, While an optional fan spreads bubbles through the solution to increase aeration. This clearly explains the floating hydroponic system.
- DWC is especially a good suite for growing fast-growing vegetables with large root systems. Like lettuce, cabbage, Swiss chard, kale, basil and most types of salad greens.
- DWC hydroponic oranges may look similar to Ebb & Flow Hydroponic gardening at first glance. However, they work very differently.
- In ebb & flow, all plants share a single nutrient solution that’s recirculated.
- In DWC, each plant has its own specialized individualized environment. And its own separate reservoir of nutrients and water which never touches other plants’ reservoirs.
What are the disadvantages of deep water culture (DWC) Hydroponic gardening
Deepwater Culture (DWC) grow trays hydroponics is one of many ways you can grow healthy and tasty fruits, vegetables, and herbs. Although it’s a simple and inexpensive way to garden, it does have its drawbacks. Here are some things to consider when deciding whether or not to set up a DWC garden for your home.
It takes a lot of space:
A typical DWC system could require at least three feet by four feet in floor space for your reservoir alone. You’ll also need enough height clearance to allow you to add nutrients and check on plants.
It can be hard to get started:
If you’re new to hydroponic gardening, there are many things you will need to know like hydroponic reservoir size before you even start building out your tank and growing media systems.
This includes choosing a system that best fits your needs as well as buying lighting, pumps, electrical timers and other pieces of equipment. You’ll also want a pH kit or meter so you can test pH levels on a regular basis.
Once you have all of these items, finding detailed instructions for setting up your system correctly will be important as well.
Not all plants grow great in deep water culture:
Although deep water culture does allow for faster growth than most other types of hydroponic systems, not all plants do great with it.
What is the Nutrient film technique (NFT)?
The nutrient film technique (NFT) is an alternative method of growing plants without using soil. Place the plants in a container. Where there’s only enough space for roots to grow. There’s also a thin film of water at or near root level, often with added nutrients.
This delivers all the water and nutrients that plants need to thrive without sacrificing any space above-ground. The main advantage of NFT hydroponic nutrient mix over other methods is its efficiency. You get more harvest per square foot. and understand how to make Hydroponic nutrient solution.
Currently, NFT offers many benefits over traditional planting methods:
- Increased crop yields
- Better control over nutrient delivery
- Precise control over temperature, humidity and light exposure
- Possibility to mechanize parts of the production process.
In NFT, plants grow in a wicking medium that soaks up water in hydroponics media. From an emitter or stream and delivers it directly to roots.
Nutrient film technique (NFT) Hydroponic gardening:
NFT works best with leafy green vegetables and herbs. The nutrient solution in reservoir hydroponics gets channel into a continuous flow system. Then it runs through a filter to remove solid particles before reaching your plants’ roots.
Aeroponics Hydroponic gardening:
Plants’ roots stay suspended in the air rather than growing in soil or using liquids as part of an irrigation system.
Spray the nutrient solution (that is otherwise a great use for conventional hydroponics) directly onto root systems via spray nozzles.
What are the advantages of the Nutrient film technique (NFT)
- The NFT system delivers a high nutrient solution to plant roots through a film of water that is only a few millimetres deep. This is amazing in mixing hydroponic nutrients.
- Plants grow with their roots that suspend in the air instead of being fully immersed in a growing medium.
- NFT tanks get to fill with large diameter polyethylene tubes. That provide hundreds of square inches of root space per tube.
- The nutrient solution flows down from above and travels along the surface of a medium, for example, gravel or expanded clay pellets, before flowing back up to a reservoir for reuse.
- Similar to drip irrigation systems used on agricultural farms, but more efficient because there’s less evaporation.
- Plus, growers don’t have to worry about contaminating their crops because they don’t have direct contact with any soil or growing media.
- A great choice for use in greenhouses where there are no irrigation lines already install.
What are the disadvantages of the Nutrient film technique (NFT)
- While they do save time and money by drastically reducing water use, they don’t necessarily reduce long-term maintenance costs.
- One of the main disadvantages of the NFT system is that it requires one or two days to establish new plants.
- Another disadvantage of the NFT system is that it uses only 10% of water than other traditional methods like drip irrigation.
Apart from all the above disadvantages, Here are a few more:
- High energy requirements
- High initial investment costs
- Continuous nutrient replacement requirements.
