High-Tech Farming introduces students to this new world by asking a simple question: What does a plant actually need to grow well? We begin with the fundamentals — water, nutrients, light, oxygen, carbon dioxide, temperature, humidity, pH and the root environment. From there, students explore how these conditions can be recreated without soil using hydroponics, vertical farming and microgreen systems. They will see how nutrient concentration is measured, how pH affects nutrient availability, and why root-zone oxygen can determine whether a plant thrives or struggles.
But can we engineer the light itself? Students will investigate how different wavelengths and light intensities influence plant growth, and how modern indoor farms use LEDs to provide specific spectra while reducing energy waste.
The journey then becomes increasingly technological. Sensors can continuously monitor the growing environment; automated systems can control irrigation and nutrient dosing; cameras can track plant development; and data can help growers identify stress before it becomes visible.
We then introduce emerging technologies such as plasma-activated water, seed treatment, nutrient management and microbial control, showing how physics, chemistry, biology and engineering can work together inside the same farming system.
Finally, students look toward the future: fully controlled vertical farms, precision agriculture, robotic harvesting, intelligent crop monitoring and even food production for extreme environments and space missions.
Understand the plant → control its environment → measure it → optimize it → build the farm of the future
