Introduction to low-cost automated hydroponic farming

Hydroponics requires a lot of automation and can manage nutrient dosage, temperature, and humidity with the help of automation. Indoor hydroponics systems have to give light and climate artificially, so automation is very important in indoor plants. Automated systems can record your plant conditions, EC, pH, temperature, humidity, etc., so you can monitor the data and operate the process according to your preferences and convenience.

A fully automated hydroponics system for growing indoor plants is very helpful for new-aged growers. Plus, you can link the automation software to your phone and access your form from anywhere. A hydroponic grow system is a sustainable method of growing with water that saves between 70% and 90%, depending on the type of plants and grow setup. Crops in hydroponic environments include microgreens, leafy greens, and medicinal cannabis.

Rockwool is one of the market’s most common substrate options, but others include perlite, vermiculite, coir, coco, clay pellets, peat moss, sawdust, sand, and gravel. Hydroponic farming is a process of growing crops without soil; the main advantages are environmental and nutrient control, water conservation, and labor reduction. This technique relies on various technologies that can be applied to the principles of automation to improve productivity and consistency.

In this method, crops are grown on water rich in essential nutrients. In addition, this method provides a solution to the problem of watering plants. Plants found in homes, workplaces, and other public places require people to water the plants manually. Instead, an automation system with a moisture sensor provided near the plant pot is used to detect whether the soil is wet or dry. 

Automated hydroponic system for plant growth

Controlled lighting

In an indoor grow room without an external (or natural) light source, but not all lamps are created equal. In addition, plants require a certain amount/quality of light depending on their growth stage and type of crop. So, we need automation here. A hydroponics automation system maintains the light your plants need with a smart hydroponics system. 

Grow all seasons

Because indoor cultivation doesn’t depend on external influences like rain and sunshine, you can often grow year-round. In addition, all seasons can be controlled through automation called smart hydroponics farming. 

Single handle run

You can run your farm alone as our system is data and command based, so the hydroponics system controller can run automatically until something goes wrong. You don’t need a worker to monitor things that are not required.

Need for hydroponic farming automation system 

There is a great need for automation systems in hydroponic farming. It is because of the tasks that require a lot of precision. Some tasks are difficult for humans to do. Hence automation system is necessary to reduce the workload on the farmers. It is ideal for production as less time and labor are required in all farming operations. Automated hydroponic farming systems have recently taken off on a large scale in India since many farmers want to increase their efficiency.

The automation system also helps in reducing labor costs, which is a great help to the farmers. The automation section offers various hydroponic farming equipment, such as fertigation and dosing controllers. It helps provide a specific fertilizer to crops by mixing with water. This equipment is very helpful in commercial farming. In addition, with their help, nutrients are provided to the roots. It is not the case with normal irrigation systems. So, the fertigation and dosing controller has the upper hand in this.

They contain sensors that detect many factors such as temperature, amount of sunlight, etc. It helps conserve water and nutrients. Farm automation is essential for the improvement of hydroponic farming. It saves a lot of resources for the farmer and hence helps the farmer to a great extent. Also, with increasing demand, farmers must embrace automation systems for faster and quality production. Many other factors, such as prices and labor, change over time.

Therefore, there is a need for automation systems in farming. Due to the advancement of technology, modern farming has started using it for the efficient growth of crops. Automation timers have different timers like reserving timers, priming timers, etc. These timers are necessary to provide nutrients and water for a specific time. So, more water and more nutrition help. In addition, temperature and humidity regulators help regulate temperature and humidity to provide an optimal environment for plants.

Advantages of hydroponic farming with automation

Reduce your labor cost – By reducing the amount of manual work, you can reduce labor costs and free up your labor for other work. 

Accuracy – Accuracy is very important in hydroponics farming because everything depends on the nutrient requirements of the plants, and with the help of automation, one and have more than one crop with different combinations of nutrients with correct nutrient dosage. 

Increases quality and productivity – Using automation, you can create an ideal climate that hydroponics plants need for optimal growth. In addition, we can provide the correct nutrients to increase our quality and yield. 

Grow lights – Grow lights must maintain intensity and wavelength to stimulate plant growth. It is determined by measuring and tuning the light spectrum. The lights are set for 14 hours ON time and 10 hours OFF time. 

Water pump – As plants grow, they absorb nutrients and oxygen from the water. Therefore, it is important to keep the water circulating in the tank. Also, stagnant water is a breeding ground for mosquito larvae and other bacteria. The water pump is set to operate every 30 minutes. 

Nutrition – The system takes samples from the tank at regular intervals to ensure correct pH and PPM levels. Corrective action is taken if the pH or ppm is below or above the desired level, and the measurement is repeated.

Setting up low-cost hydroponic farms with automation

More and more people are trying to set up hydroponics farms, as it does not require a large area and the cultivation process requires very little water. Moreover, IoT systems have allowed farmers to automate the hydroponic farming process to a certain extent. For example, some areas tend to get waterlogged during winter, which can stop the cultivation process altogether. Water temperature sensors installed on the hydroponics farm can detect the drop in temperature and alert the farmer accordingly.

Similarly, a pH sensor can detect changes in nutrient levels and pump out the appropriate amount of minerals. An assortment of sensors and controllers, such as ESP-8266, Arduino and Raspberry Pi, etc., can be used to instrument and automate the hydroponics farm. Automation is the key for growers looking to optimize, modernize, and expand their businesses for sustainable crop production. The overall benefits of automating your growing operation are vast and numerous.

Regardless of how you want to develop your growing enterprise, automation offers universal benefits that allow you to achieve your goals. Automation hardware is everything included in a basic hydroponic system that will allow autonomous monitoring and control. It includes sensors for air, water, and electricity measurements, peristaltic pumps, and power control boxes that will modulate fans, lights, humidifiers, or other devices.

Automated hydroponic greenhouse systems 

Older or more traditional greenhouse systems use soil as a growing medium. It has been a favorite among growers because, at one point, it was the only growing method. However, modern greenhouse growers are incorporating hydroponics into their greenhouses, i.e., replacing soil with water. It gives them complete control over what enters their plants (insects and pests). In addition, an automated hydroponic greenhouse system controls water quality and the nutrients needed to feed your plants.

Imagine having a system that automatically takes care of irrigation water, greenhouse water recycling, and multiple feed formulas that are delivered to your crops on a daily schedule. It significantly increases yield and can reduce your labor, energy, and fertilizer costs. The difference between a traditional greenhouse and a hydroponic greenhouse is the method chosen to grow soil or less soil. Accordingly, you need to choose the appropriate fertigation system and configure it to provide your greenhouse crops with sufficient clean water and nutrient solutions.

Likewise, for your hydroponic greenhouse to produce, you’ll need the right water pump, tank, controls – and of course, the right support system for automation. Your hydroponic greenhouse should also have a lighting and ventilation control system. So, you will need to implement a combination of a proper hydroponic drip irrigation system and a greenhouse automation system. In a hydroponic growing system, crops are suspended in a water solution.

Sometimes, they can be grown in other mediums without soil, like perlite, Rockwool, vermiculite, coconut coir, etc. In an active system, pumps circulate nutrient solutions and aerate the plants’ roots in the water or non-water, non-soil medium. In a passive system, controls or instruments are used in the greenhouse without technology. The nutrient solution is fed to plant roots without a pump using capillary action, gravity, or flooding. Then it relies heavily on manual labor, and it’s hard to get a competitive edge with this system.
