Controlled root zone

A controlled root zone is a particular area around the plant’s root where the growing conditions are carefully managed. Various factors like water, nutrients, temperature, and even air circulation can be controlled in this zone. The reason for regulating this area is to allow the plant’s roots to grow in the best environment, which helps its growth and overall health. 

Controlled root zones are useful for researchers, gardeners, and farmers who want good plant growth and health. For farmers, these zones provide better crop yields. Gardeners can use this to grow healthy plants with better root systems. Scientists can use controlled zones to study plant responses and develop stronger varieties that can survive extreme conditions.
