So, this blog will explore all the recent innovations in hydroponics technologies that are reshaping the way we grow food.

The Evolution in Hydroponics 

Evolution in Hydroponics

In the late 1920s, Dr. William F. Gerick experimented with nutrients in practical and commercial crops growing outside. He is the one who coined the term “Hydroponic”. It comes from the Greek word where ‘Hydro’ means water and ‘Ponos’ means water working. However, it’s observed that hydroponic methods have been used since long ago. People from the 6th century utilized the Euphrates River as the source of their irrigation.

The first proof of using the hydroponic method was observed in the 10th century when Aztec people (known for agriculture, land, art, and architecture) used a floating garden in a nearby lake. However, the ancient technologies used in hydroponics can’t be seen through. Now the latest technology in hydroponic systems has been changed more than ever before. That’s why the importance and use of hydroponics is increasing day by day. 

Some advanced technologies and methods that have recently been used in hydroponic systems have transformed the working process of hydroponic growers. Here is a list of the latest technologies used in hydroponic systems:

  • Automation and loT
  • Artificial Intelligence 
  • LED Lighting Innovations 
  • Hydroponic Robotics 
  • Smart Sensors 

Key Technologies in Hydroponics

Now the question is what technology is used in hydroponics? The revolution of AI and automation has already started its mission of changing the world of indoor cultivation. Hydroponic farmers are now focusing more on data critical and automation development rather than working on laborious mundane tasks.

As automation progresses, growers can easily manage and maintain growing conditions, seeding, harvesting, and packaging. This ultimately gives laborers and growers a huge amount of time to do tasks like documentation and varieties of growing operations. They can also learn and observe what is happening on the farm.

So, this is certain that the innovations in hydroponics technologies are shaping the grower’s cultivation process. Now, let’s take a closer look at some of the mainstream agricultural techniques that are used by hydroponic growers. 

Nutrient Film Technique (NFT)

NFT (Nutrient Film Technique), also called Nutrient Delivery System, is an active hydroponic system where growers use a pump to move a thin layer of nutrient solutions through small channels. Thus, the plant’s roots can dip into them and absorb nutrients. This nutrient is equivalent to fertilizers and chemicals used in traditional agriculture. 

Besides, NFT is a sustainable system as it protects the conservation of water compared to traditional farming methods. Also, unlike other methods, it makes sure a sufficient supply of water, nutrients, and oxygen to the plant roots. In a hydroponics system, farmers can grow lettuce, herbs, and other leafy greens. However, several hydroponics supplies are required for growers to be successful.

Here are a few components of Nutrient Delivery Systems (NFT):

  1. Water Pump: It transports nutrient solutions from the reservoir to the grow trays via a water pump.
  2. Air Pump: This device oxygenates and aerates nutrient solutions.
  3. Growing Channels: It takes less water to feed your plants properly. Growing channels are up to 15 m long and have a slope of between 1% and 3%.
  4. Nutrient Solution: Nitrogen, phosphorus, and potassium are the three most important elements.

Controlled Environment Agriculture (CEA)

To be a successful hydroponic grower, you need an optimal environment. Controlled Environment Agriculture (CEA) is a technique used in indoor greenhouse gardening. In this process, growers create an optimal growing environment for the indoor crops, and as the term suggests this is done by controlling some of important environmental factors. The blessing of innovation in hydroponics made it possible to control factors like indoor temperature, humidity, light, and carbon-di-oxide (CO2) levels. Besides, growers use the grow tents facility to achieve an ideal environment for their plants. And it also offers hydroponic growers with fresh environment compared to outdoor farming. CEA doesn’t only provide the facility with controlling environmental factors but also gives the hydroponic growers to grow crops year-round. 

Automation and loT

The latest technologies like automation and the internet have changed the way we work, live, and make things in our life. Hydroponic isn’t any different from it. Growers are continuously utilizing new innovations in hydroponics technologies to improve and smoothen their cultivation process. However, automation and loT (Internet of Things) offer devices, sensors, and data analytics to accurately monitor and manage the hydroponics system remotely. These advanced technological facilities are helping farmers to create a more productive hydroponic growing system.

For instance, nowadays, hydroponic growers can benefit from carefully placed IoT sensors that monitor water quality, nutrient concentration, electrical conductivity (EC), and pH levels.

Besides, these sensors collect real-time data about mineral nutrient levels and send them to the central hub so that crofters can get valuable insights into their indoor farms. 

Vertical Farming 

In simple words, vertical farming is one of the key technologies to grow crops in vertically stacked layers instead of following traditional horizontal agriculture. For instance, skyscrapers, and shipping containers. It is used in most soilless farming methods like hydroponics, aquaponics, and aeroponics. However, this type of farming is intended to use the unused spaces of urban areas. Because of industrialization and urbanization, the cultivation space is decreasing on a regular basis. Here vertical farming method helps the hydroponic growers to make the most out of limited areas. 

Here are some of the core benefits of Vertical farming:

  • Climate control
  • Year-round production 
  • Utilizing unused urban spaces 
  • Higher yields due to control over environmental factors 

Artificial Intelligence (AI)

One of the most revolutionary innovations in hydroponics technologies is Artificial Intelligence (AI). Now, hydroponic cultivators are using AI to grow healthier crops, control applications of pesticides, and monitor soil and growing conditions.

With AI, growers can analyze farmer data and improve food supply chain management. Before AI, it was quite challenging for the crofters to pick the ideal time for seed plantation which became easy after the arrival of artificial intelligence.

Now farmers can learn data about weather forecasts and choose optimum seeds. In short, this mind-blowing technology reshapes the agricultural process and gives benefits to farmers to grow more crops with fewer resources.

Latest Technological Impacts

We have so far discussed the key technologies that are being utilized by hydroponics growers. Now, let’s explore the latest innovations in hydroponics technologies that are reshaping the future of the indoor cultivation process.
