Mononutrients are essential for the development of the plant. These liquid minerals are easily soluble and can therefore be directly absorbed by the plant.
Our pure mono nutrients are produced from exceptional ingredients, just like our main nutrients (CANNA TERRA, AQUA, HYDRO and COCO). All of our mononutrients are 100% nutrient compatible. Use with CANNA nutrients for best results.
CANNA Iron fulfils a number of important functions in the plant's total metabolism and that makes it an essential element. It plays the major part in photosynthesis and a large part in the production of chlorophyll. Furthermore it has a big influence on physiological processes and on the energy system.
CANNA Iron can be absorbed directly, can be mixed with all fertilisers and is stable with each pH. It is a perfect product to replenish iron deficiency and to stimulate the growth and bloom.
