CANNAZYM is indispensable if you are going to reuse substrates for growing. The root remains will be rapidly broken down and transformed into advantageous nutrients; infections will be prevented and the air/water relation in the root environment will be improved. You can use CANNAZYM during the whole growth cycle.
CANNA only works with high graded nutrients and chelates, which are immediately and completely available for the plant. The bottle is made of polyethylene (PVC and cadmium free), a recyclable plastic.
