Yield was about 10% bigger when i used cannazym plus PK 13/14 than just Coco A+B
But i was doing a microgrow so it was a small difference. On a bigger scale though....it would definately outperform.
Havent tried cannaboost yet.
Have you had the chance to compare Canna coco's A+B with GH 3 part series? I'm hesitating between the two and GH is more cost effective...
