In the greenhouse, the primary focus is usually on above-ground factors, particularly the condition of the crop. But many essential processes take place in the root zone as well. 

For instance, a good and healthy root environment is the basis for optimal plant balance, a healthy, active crop and high yields. To keep the root zone – and therefore the plants – in peak condition, there are six key factors to consider: water content, EC, pH, oxygen, microbiological life and temperature. In other words, The Big Six.
