Macronutrients

Definition - What does Macronutrients mean?

In cannabis cultivation, macronutrients refers to the three plant nutrients that the marijuana plants require in much higher doses (quantities) than micronutrients.

There are three macronutrients, which are sometimes referred to as primary macronutrients, are nitrogen, phosphorus, and potassium. Their chemical elements, N, P, and K, are often expressed on fertilizer and nutrient packages as the product's N-P-K value.

In addition to the three primary macronutrients cannabis requires, there are three secondary macronutrients that are required (in lesser quantities than primary macronutrients, but still higher amounts than micronutrients). The secondary macronutrients are calcium, magnesium, and sulfur. Many plant scientists believe silicon to be a secondary macronutrient as well.


Hydrolife explains Macronutrients

In doesn't matter what strain of cannabis one is growing, all types of cannabis require the same quantities of macronutrients.

Each macronutrient has a particular benefit or function in the garden. For example, nitrogen is essential for building proteins and producing carbohydrates; it is also essential for plant cell division (growth). Phosphorus helps with root growth, seed formation, and plant maturity. Finally, potassium is important for disease resistance and boosting flowering.

As for the secondary macronutrients, sulfur helps develop vitamins, aids in seed production, and is important for forming amino acids. Magnesium is the key to chlorophyll production and helps plants to take in phosphorus and iron. Calcium helps in respiration and cell division, while silicon is said to strength plant cell walls.

Cannabis plants are considered hungry plants; they need a constant supply of nutrients practically at all times. They key to successful cultivation is matching your plant's feeding schedule with their stage of growth. For example, seedlings require a lot less nutrients than larger adult plants preparing to set flowers.

While not as essential to plant growth as macronutrients, there are micronutrients cannabis plants require as well. They include chlorine, molybdenum, copper, iron, manganese, zinc, and boron.
