Canna Coco is an inert Coco mix. You will need to provide all nutrients and feed daily to runoff. I have seen some ripper plans grown in Coco,.and have used it myself. I didn't like having to feed every day during flower however.
Canna Terra Professional is their peat based soil mix. Holds more water and requires less nutrient feeding, twice a week to three times a week max. I used a similar mix and didn't have to feed until week three or four if I remember correctly.
Think of Coco as basically a hand watered drain to waste hydro setup, but with Coco coir instead of hydroton or perlite/vermiculite as a medium.
