If there was ever a cannabis fertiliser company that needs no introduction, it's probably the Dutch brand Canna. Specialists in plant nutrition in various substrates (soil, coco, hydroponics and aeroponics) since the early 90s, the solidity of their results and the good information they provide to their customers have made them a benchmark in the world of cannabis cultivation.
Today we are going to take a look at their products and, above all, at their nutrient schedules, those charts that fertiliser manufacturers provide us with to guide us when it comes to providing the most complete and balanced diet possible for our plants. As many of you know, these tables give us the doses to use for each product at each stage of the plants' life, as well as the optimum pH and EC ranges for maximum development.
As you will see, we will study all the Canna nutrient charts, referring to substrates such as soil (we will see the charts for mineral as well as organic fertilisers), coco fibre, hydroponic systems (clay, rockwool, etc.) and, finally, aeroponics, those soil-less systems in which the irrigation water or nutrient solution is usually reused instead of being discarded, recirculating it from the tank to the irrigation system and back to the tank. But best not get ahead of ourselves and first, let's look at the products we are going to use in each type of growing medium.
