Fifth, water ways and water : ground water spray should be less drenching . It normally takes longer isochronous stromal drenching . Water should be biased weak acid , conditional, water softener PH value should be around 6.0. Six Ventilation: " The ventilation Portland ." The circulation of air is very important, but also can reduce the incidence of disease. Air circulation is also just as important within the matrix of the root , so we recommend use granular material , and water must be drenched , fresh air into the matrix the .
