The Cannabis Nutrient Menu
3.March 2021 | Manuela
Plants need a lot more than light and love. Cannabis is also happy to have a balanced menu. What exactly is on the menu and, more importantly, why, opens our two-part series on cannabis and its nutrients. Then, in part two, we'll look at how cannabis communicates its needs so it can place its order for us.
"Photosynthesis" - For many, the first big term in their vocabulary. In the chloroplasts of the plant, carbon dioxide and water are converted into glucose with the help of light energy. This releases oxygen, which in turn is released into the environment. The glucose is stored as starch or processed into cellulose. This is the basis of any contented plant, including cannabis. Outside of this foundation, however, the cannabis plant needs quite a bit of supporting nutrients, which are either obtained from the environment or supplied artificially in the form of fertilizer.
14 Nutrients for the Cannabis Plant
N and P and K and Ca and S and Mg. Then some Fe and B and Mo and Mn and Cu and Cl and Zn and Co. That's the alphabet salad that a cannabis plant likes to have on the menu. What are the exact ingredients and why are they important?
The Difference Between Macro- and Micronutrients
There's more to this menu than meets the eye, isn't there? If you want to grow successfully, you should always keep these nutrients in balance. Basically, there is a distinction between macro- and micronutrients. Macronutrients include nitrogen, phosphorus, potassium, calcium, sulfur and magnesium. All others end up in the category of micronutrients.
As the name implies, only small amounts of the micronutrients are needed. The macronutrients, most notably nitrogen, phosphorus and potassium, also known as N-P-K, are match-deciding building blocks for a successful crop.
