Over the years, technology has evolved and revolutionized in almost every field. Our perspective towards life as well as the world has drastically changed with the rise in technology. This tech-savvy world has almost brought our resources and tools at fingertips. But that is not it, technology is not just refrained from work or games it is much more than that. It is drastically impacting our lifestyle and well-being. Hydroponics and Aquaponics is the latest example of use of technology in an eco-friendly, natural, organic and sustainable way.
As the world continuously tries to evolve in various sectors like health, so are the gardening techniques. Hydroponics and Aquaponics are few examples of gardening methods that are drastically being adopted by people. Probably, because these techniques can yield much more than the conventional method of soil gardening. Now Let us have a close look at what these techniques are and what they can offer to us.
What is Hydroponics?
Hydroponics is an organic gardening method in which plants are grown in liquid, sand, coconut fiber, clay, gravel or any material that supports plant growth other than soil. Water carries the nutrients to the roots which are increased along with liquid plant food. All in all this method uses water and chemical nutrients to cultivate the plant.
Benefits of Hydroponics:
- No use of soil which ultimately results in saving space and other issues like weed growth, pests, and other soil-borne diseases.
- Faster growth, higher yields, and better quality crops.
- Water conservation because hydroponics uses 90% lesser water than traditional methods of gardening.
- Nutrient levels can be controlled which results in less requirement of nutrients.
- Can be grown all around the year.
What is Aquaponics?
Aquaponics combines the technique of aquaculture with hydroponics. Aquaponic is a balanced ecosystem in which fish and plants are in a symbiotic relationship that mutually benefits the plants as well as the fish. Just like, hydroponics growth media and pumps are used in this process, but Aquaponics uses organic fish waste as a nutrient for the plants. Plants naturally help in cleaning out the water in aqua tanks, so it requires less cleaning and maintenance. Aquaponics is widely used across Australia as an organic method to cultivate so many plants and crops.
Benefits of Aquaponics:
- No additional nutrients need to be used as it uses organic waste produced by the fish as a fertilizer.
- The organic fish waste can easily be disposed using the drain and can also be used in composting.
- The natural system easily balances out and does not require much maintenance. Only periodic checking of pH, nitrate and ammonia levels is required.
- Can be grown all around the year.
Which one is better?
Both systems work well as they are organic and have advantages over the conventional methods of soil gardening. However, Aquaponic seems to be more beneficial in production as well as is suitable in various environmental conditions. In Aquaponic system plants grow rapidly and the yields are better. The overall system also produces fish that benefits as an additional income, and it works on feeding the fish which is cheaper than feeding the plants. It also saves water due to recycling nature as compared to hydroponics.
From a commercial point of view, Aquaponic culture has a stronger exposition than its counterpart hydroponic. But for a gardener, it is more subjective whatever is suitable you can choose, as both are organic methods of gardening.
An aquaponics system offers food to both vegetarians and non-vegetarians as fish and plants are grown in the same system. In the aquaponics, fish holds a little more important position as the growth of plants depends on it. The waste of food and fish is dissolved in the water. The waste actually consists of all nutrients essentially required for the growth of plants. The water containing these nutrients is transferred from the fish tank to the growth bed. These nutrients are extracted by plants and the purified water is returned to the fish tank and a healthy environment is created for fish. Therefore, one should rear the right fish. Continue reading
Aquaponics is a re-circulating environment in which aquatic animals and plants are cultivated in one system. The term re-circulating environment is used because of the circulation of water between the fish tank and the grow bed. The decomposed food and fish waste in the fish tank produce nutrients which are dissolved in water. The water containing nutrient from the fish tank is then drawn off to the grow bed. Nutrients are extracted by the roots of plants and used for growth.
For growing food and fish, following are the equipment and accessories you need for aquaponics system:
- Fish Tanks: The size of the fish tank depends on the number of fish you want to nurture. You will also need stands for positioning the tank.
- Grow bed: Fruits and vegetables are cultivated on the grow bed.
- Bio-filters: These filters degrade and process water pollutants biologically for controlling water pollution and keeping the system running efficiently.
- Clarifiers: These are used for removing solids from water and also the water in the recirculation system when required.
- Pumps: These are required for circulating water between the fish tank and the grow bed. Pumps also pass the water through bio-filters for cleaning.
- The oxygen system: Excellent oxygen distribution system is essentially required for keeping fish alive and healthy.
- Fish and plants: Different types of plants are grown in different types of aquaponics systems. Choose the right fish for supporting the plant environment.
Apart from these, there are various other smaller accessories like pipes, tubes etc which are required to keep the system running. The best place purchasing all these equipment and accessories is Hydroponicxpress.

Hydroponics and aquaponics methods are widely used in regions where there is no soil available for vegetation. In some regions, the fertility of the land is not enough for growing crops. These terms are often confusing for those who are not or a little acquainted with soilless methods of growing plants. Hydroponics and aquaponics do have some similarities as both are soilless methods growing crops. However, these terms are not synonyms. In Aquaponics, a hydroponic s integrated with aquaculture in a controlled environment. On the other hand in hydroponics, a solution of nutrients is used for growing plants. Continue reading
Most of the readers of this post might not be familiar with hydroponics. The term hydroponics was coined in 1937 by Gericke after he grew tomato vines in his backyard in a solution of nutrient without using soil. It is a subset of soilless culture which is a technique of growing plants without using soil. It is the use of nutrient solution which differentiates hydroponics from other soilless culture techniques.
Till now, following six hydroponics methods have been developed:
- Water culture: It is the simplest and least expensive method of hydroponics. A platform made up of Styrofoam holds plants. The nutrient solution is kept directly below the platform. This system consists of an air pump and an airstone. When air is supplied to the airstone; the airstone in addition to supplying oxygen to the roots also creates bubbles of nutrient solution.
- Wink system: This method of hydroponics makes use of capillary action to supply nutrient to the root. This system comprises of wicks, a reservoir and growing medium. Perlite, ProMixs, coconut fibre and vermiculite are the most popular growing mediums used in the wick system. Nutrient solution to the growing medium is supplied through wicks using capillary action.
- Flood and Drain method: This system consists of a timer controlled pump submerged in the reservoir, and a grow tray. The pump is used to flood the grow tray with nutrient solution and then drain it by drawing the nutrient solution back into the reservoir. In this system, it is required to use growing mediums which can retain more water. Coconut fibre, Rockwool, Vermiculite are the most suitable for this method.
- Drip system: Like Flood and drain method, drip system also consists of a grow tray and a timer controlled pump submerged in reservoir. The pump is turned on by the timer and nutrient solution is supplied to grow tray using drip lines. Recovery and non-recovery are the two types of drip system. In recovery drip system, the excess solution is reused. In the non-recovery drip system, the excess nutrient solution runs-off.
- Nutrient Film Technique:F.T. system consists of a pump (without any timer) submerged in the reservoir. This pump continually pumps the nutrient solution into the growing tray. This system uses air as growing medium. The solution flows over roots of plants without any interruption and then is drained back into the reservoir.
- Aeroponic: This system is quite similar to N.F.T. as it also uses air as growing medium. The root of a plant hangs in the air and is misted with nutrient solution. Roots being exposed to air are likely to get dried quickly. Therefore, misting is done for a few seconds after a few minutes using a timer controlled pump submerged in the reservoir.
