The web page says "BIOCANNA Bio Terra Plus is a reduced peat potting blend, the best white peat, coco coir, and organic bases without any materials of an animal origin." You might contact Canna and ask them what those "organic bases" are. Does the bag show an NPK ratio, a guarantee analysis? (I wonder if it has nutrients in it. I.e., organic bases like fish bone meal, or cottonseed meal.). It sounds like it should be treated like a soil (not soilless peat or coco). But, that's not clear either because most soils have some nutrient content already in them.
yes it has nutrients in it some batguano and other stuff....it is soil i think i read everything about it!!
i will wait till the soil it's very ddry befdore watering!!!
