What is the difference between hydroponics and aquaponics?
Hydroponics and aquaponics are soil-free methods of growing crops. These hydroculture gardening methods are applicable in the greenhouse so that the grower can take care of environmental factors.
The main difference between aquaponics and hydroponics is that the former is the growing of plants in a soil-free medium and cultivation of fish while the latter is the growing of plants in a soil-free medium only.

Comparison Table (Hydroponics vs Aquaponics)
|Meaning||It is the technique of growing plants in a soil-free medium and it involves the use of water||It is a combination method of growing plants in water and cultivating fish at the same time|
|Nutrient Source||Chemical nutrients||Organic matter released by fish as wastes provide nutrients|
|Cost-Effectiveness||Less cost-effectiveness since chemical nutrients are increasing||High cost-effectiveness as organic matter supply nutrients|
|Startup Speed||Fast to start||Slow to start|
|Operating Temperature||Usually lower to prevent bacterial growth||Higher temperature to encourage the growth of nutrient-rich bacteria|
|Productivity||Lower yields||Higher yields|
|System Unloading||Require regular flushing at lower intervals||It is a looped system where nutrients pass around the system and are used|
|Ease of Maintenance||A higher degree of maintenance||Easy to maintain|
|Mechanical Failure||Less prone to failure||Highly prone to failure|
|Insect Control||Easy to eliminate insect infestation||Difficult to get rid of pest infestations|
|Disease Prevalence||Susceptible to root rot||Not prone to root rot|
|Electrical Conductivity||Can damage the plants due to high conductivity||Not a concern at all|
|Ecosystem||Not an ecosystem||It is an ecosystem|
|Plant types||Heavy feeder plants||Plants that need low nutrients|
|Grow Bed depth||About 6 inches||About 12 inches|
What Is Hydroponics?
It is a technique of growing plants without soil. But the plants will need nutrients and water to flourish. The method of cultivation works better than traditional gardening.
The type of gardening usually takes place in a greenhouse and it is quite easy to startup when compared to aquaponics. However, it is less cost-effective since you have to purchase chemical nutrients.
The water in the system is recycled after the filtration process. It’s something that is making hydroponics easy to maintain.
Some of the popular crops that can be grown using the techniques are tomatoes, potatoes, strawberries, cabbage, cauliflower, mint, basil, lettuce, and green beans.

Advantages of Hydroponics
- No soil is needed
- Stable and produce high yields
- Do not experience damages from pesticides
- It is an eco-friendly type of gardening
- Lower nutrients requirement
- Lower water requirements due to recycling
Disadvantages of Hydroponics
- Difficult to get organic certification
- Less cost-effective
- Not eco-friendly due to release of chemical nutrients
What Is Aquaponics?
It is a method of growing plants in a soil-free medium and also the cultivation of fish on the same platform. The plants utilize the organic waste release by the fish as the source of nutrients.
Aquaponics gardening is simple and easy to start. It has higher cost-effective since the grower does not need to buy chemical nutrients for the plants.
The organic matters unload in the system is eco-friendly. They do not contain chemical ingredients that might harm the environment.
Some of the popular crops that can be grown using aquaponics are kales, spinach, lettuce, radish sprout, wheatgrass, mint, basil, swiss chard, squash, pepper, cucumbers, arugula, and pak choi.
Advantages of Aquaponics
- An excellent marketing tool since many people prefer organically grown vegetables
- Attract the attention of many consumers
- It is exciting and rewarding in terms of yields
- Create an eco-friendly ecosystem
Disadvantages of Aquaponics
- Building the system is complicated
- Time-consuming when recycling
- Not suitable for beginners
- The high initial cost of building the system

Main Difference between Hydroponics and Aquaponics
- Hydroponics involves growing plants alone in a soil-free medium while aquaponics involves cultivating both fish and plants in a soil-free medium.
- Hydroponics requires a supply of water and chemical nutrients while aquaponics requires a supply of water alone.
- Hydroponics is suitable for beginners and experienced hands while aquaponics is only ideal for experienced hands.
- Hydroponics is not eco-friendly whereas aquaponics is environmentally friendly
- Hydroponics is less cost-effective whereas aquaponics has a higher cost-effective
- Hydroponics have lower production yields whereas aquaponics has a higher production yield.
Similarities between Hydroponics and Aquaponics
- Both are gardening techniques that involve growing crops without soil
- Both rely on water as the main delivery of plant nutrients
- All nutrients will artificially be provided to the crops
- Both farming techniques experience less pest and disease damages
- Both experience less wastage of nutrients
