Vertical Farming: leveraging KUNBUS’ Revolution Pi for enhanced efficiency and productivity
require slightly cooler or warmer conditions. Proper humidity levels are necessary for plant transpiration, nutrient uptake, and overall health. Excessive humidity can lead to fungal growth and disease, while too little can cause crops to become stressed and dry out. Most crops require relative humidity levels between 50 and 70%, although some tropical species require higher levels. CO2 levels in growing environments also have a direct impact on plant growth and productivity. As plants photosynthesize, they absorb CO2 from the air and convert it into the energy needed for growth and development. In the controlled environment of a vertical farm, CO2 levels can be monitored and adjusted to optimize photosynthesis and boost crop yields. Sensors and injection systems allow growers maintain the ideal concentration for their specific crops, maximizing the efficiency of photosynthesis and accelerating growth rates. Air speed, or the movement of air within the growing environment, must be carefully controlled in vertical farms. Proper circulation helps to regulate temperature and humidity, prevent stagnation, and ensure even distribution of CO2 and other nutrients. In addition, gentle airflow can stimulate plant growth by mimicking the natural wind conditions that plants would
experience outdoors. Automation controls, such as fans and ventilation systems, can maintain an optimal air speed for crops, promoting healthy growth and minimizing the risk of damage or stress. Automation controls: optimizing growth conditions and production The basis of any successful vertical farming operation is the ability to monitor and regulate the environmental factors that affect crop growth and health. Automation controls are the eyes, ears, and hands of the farm, continuously gathering data from a network of sensors and using it to make real-time adjustments to parameters such as temperature, humidity, CO2 levels, and light intensity. By maintaining ideal
horticultural conditions, these systems maintain an environment in which crops can thrive, free from the stresses and fluctuations that can hamper crop growth. In addition to environmental regulation, automation controls also play a crucial role in the precise management of water and nutrients. Hydroponic and aeroponic growing systems depend on the delivery of carefully balanced nutrients to the plant roots, and slight deviations from the optimal formula can have an outsized impact on crop health and yield. Automated systems ensure that each plant receives exactly the right amount of water and nutrients at the right time, minimizing waste and promoting healthy growth. By monitoring nutrient levels and adjusting delivery rates, these systems offer a balance of resources, optimizing plant uptake
conventional farms, crops are transported over longer distances, leading to more emissions, higher transportation costs, and reduced freshness. By strategically locating vertical farms near urban centers, the farm-to-table journey can be considerably shorter, cutting down on transportation costs and associated carbon footprints. Environmental factors to monitor and control in vertical farms In vertical farming, maintaining an optimal climate is of utmost importance for the health, growth, and productivity of the crops. Four climatic factors that require precise monitoring and control are air temperature, humidity, CO2 levels, and air speed. Each of these parameters is necessary to create an ideal growing environment, and even slight deviations from the optimal range can have a significant impact on plant development and yield. Air temperature is perhaps the most fundamental climatic factor in vertical farming, as it directly influences plant growth, metabolism, and transpiration. Different crops have varying temperature requirements, and it is vital to maintain the appropriate range for each species to ensure optimal growth and prevent stress. For hydroponics, crops thrive in temperatures from 18°C and 28°C (65°F to 82°F), although some may
Vertical farming offers a sustainable, efficient approach to growing crops by cultivating plants in vertically-stacked layers within controlled indoor environments using various technologies.
By breaking free from the constraints of traditional outdoor farming, vertical farms have the potential to redefine how we produce food in urban areas where land is scarce and the demand for fresh, locally-grown produce is higher than ever. This article explores the role of automation in vertical farms and explores how KUNBUS’ Revolution Pi platform, combined with sensor technology and LED lighting solutions, can be utilized to optimize vertical farming operations. A sustainable solution for food production One of the most significant benefits of vertical farming is its space efficiency. Unlike conventional farms that require vast expanses of land, vertical farms can grow a substantial amount of crops in a fraction of the space. By stacking growing beds vertically and utilizing advanced hydroponic or aeroponic systems, these facilities can maximize their yield per square foot, making vertical farming ideal for cities with limited or expensive real estate.
In addition to space efficiency, vertical farms can also improve water conservation. Conventional farming methods rely on extensive irrigation systems that can lead to water waste and runoff, depleting natural resources and contributing to environmental degradation. In contrast, vertical farms employ closed-loop hydroponic or aeroponic systems that recirculate water and nutrients, dramatically reducing water consumption by up to 95% compared to other farming techniques. Another benefit of vertical farming is its ability to produce crops without using harmful pesticides or herbicides. In outdoor farms, pests and diseases pose a constant threat to crop health and yield, forcing farmers to rely heavily on chemical treatments to protect their harvests. However, the controlled environment of vertical farms minimizes the risk of infestations and the spread of plant diseases, virtually eliminating the need for pesticides and herbicides. Vertical farming also provides a solution to the problem of food miles – the distance that produce travels from farms to tables. In
