What are the main cannabis nutrients?

Macro nutrients from air and water

Carbon, Hydrogen and Oxygen are macro cannabis nutrients from air and water. This makes them easy to acquire, meaning that shortages of these nutrients are not usually encountered.

Carbon (C)

Carbon is absorbed via CO2 gas through pores on leaf surfaces known as stomata. Carbon is used extensively throughout the plant for growth where it is a key building block of cellulose.

Hydrogen (H)

Photosynthesis allows light energy to be used by the plant to split water into hydrogen and oxygen ions which are then used by the plant.

Oxygen (O)

Just like Hydrogen, Oxygen is derived from water using energy derived from photosynthesis. Oxygen can also be absorbed through the leaves and roots.
Macro nutrients from soil

Nitrogen, Potassium and Phosphorus can be taken from soil. Those using best cannabis nutrients may notice data on their nutrient labels which details the specific ratios of N, P & K.

Nitrogen (N)

Nitrogen is a mobile nutrient when in the form of a nitrate. Soil based nitrogen requires microbial action to convert it into a plant-usable form. Nitrogen is used extensively for growth and development. It is a building block for protein formation.

Phosphorus (P)

Phosphorus plays a key role in the transfer of energy from photosynthesis. It is also critical to the usage of starches and sugars. Also vital for bloom, often supplied via a ‘PK’ boost.

Potassium (K)

Potassium is important for plant growth, root growth/structure, tolerance of stress and metabolic functions. It is also used in creation of enzymes and proteins.
