CANNAZYM can be given continually. This is most easily achieved by mixing it with the nutrient mixture in the proportion of 10 ml/gal (1:400), or it can be given once a week in the proportion of 38 ml/gal (1:100). It is also possible to add the CANNAZYM to the nutrient tank when it is just 25% full at 38 ml/gal (1:100). CANNAZYM also makes the medium more suitable for re-use.
