A plant does not function alone. Around its roots, on its leaves and even inside its tissues, it lives together with a community of microorganisms. Together, the plant and these microbes form what is known as a holobiont.

Water, minerals, sugars and signalling molecules are constantly moving through a plant. At the same time, the chemical conditions inside its tissues are changing. Understanding these processes gives growers a better idea of what is happening inside the crop, not just what is visible on the outside.

A fertilizer schedule is more than a list of nutrient concentrations. It reflects what the plant needs under specific growing conditions.

Most growers monitor relative humidity, but absolute humidity often tells the real story. Learn why this distinction matters for plant activity and greenhouse climate control.
