A frequently asked question of the grower is: “Will my potting soil not be too wet, after adding FIBA-ZORB PLUS, and lower the air filled porosity (AFP), especially in the winter months when there is less evaporation and growth of the plant?”.
 

FIBA-ZORB PLUS is an excellent wetting agent because it will ensure that not too much water is retained by the potting soil and in this sense the wetting agent is controlling the moisture level and slightly increases the AFP during the more dormant growing months when less moisture is required by the plant.
