CANNA’s products for cultivating on soil are called CANNA Terra. CANNA Terra can be used for cultivating in both pots & open soil, indoor & outdoor. The biggest advantages of growing in soil are its ease of use and the tolerant nature of this medium, as a result of which small deviations in the feeding given do not have to have serious consequences for the yield. However, one disadvantage is that different types of soil retain different nutritional elements which make precise control of the nutrient dosage difficult. Terra nutrients have been developed to overcome dosage problems and give good results with every type of soil.
