Yes, so long as it's hygrozyme and not hydrozyme. I haven't used it because I can get the Cannazym but I use close to Canna's recommended dose. For the PBP I use about half what Botanicare's suggestion.
You will love growing DWC. Huge undergrowth and just huge yields with some descent veg time. Ive never seen roots get as big as they do in dwc. I seen a five gallon bucket just full of roots its insane and pretty simple.
