The cannabis plant has several structures, many of which we can find on any ordinary flowering plant species. Cannabis grows on long skinny stems with its large, iconic fan leaves extending out from areas called nodes.
Also known as “buds,” the flowers of a cannabis plant are the fruits of your labor. They contain the cannabinoids and terpenes that get you high or offer health benefits. Flowers only grow on female cannabis plants and must be dried before consumption.
Parts of the cannabis plant
These are the first leaves to grow from the seed after germination. They usually come in pairs, and seeing them is a sign of successful germination and that your plant is on its way to growing healthy and strong.
Despite their minute size, it’s hard to miss the blanket of crystal resin on a cannabis bud. This resin is secreted through translucent, mushroom-shaped glands on the leaves, stems, and calyxes.
Because of this, it’s important to look into the genetics of the male plants. Their shape, rate of growth, pest and mold resistance, and climate resilience can all be passed on to increase the quality of future generations.
This is what cannabis seeds need to sprout:
If you really want to reuse your old soil, you need to amend it with fresh nutrients. Before that, you need to make sure that your soil is free of contaminants.
Correct pH levels
Although heat, pH, overwatering, and soil are important, we’ve added the most vital point to the bottom of the list: lighting! Cannabis plants depend on light to create energy and thrive. At the end of the article, you’ll learn the best way to illuminate your plants.
A common reason for heat stress is when your grow lights are too close to the plant canopy. If you spot signs of light burn, such as curled, wilted, and brown leaves at the top of your plant, move your lights further away.
Mycorrhizal fungi participate in a give-and-take relationship with cannabis plants. These species form networks of thin, hair-like filaments in the soil—known as mycelium—and produce enzymes to break down organic matter.
Although the flowers get most of the attention—and rightly so—every part of this complex species has a critical and interesting function. As a cultivator, it helps to familiarise yourself with the anatomy of the cannabis plant. In doing so, you’ll develop an eye for what your plant requires, what it needs less of, and when to harvest.
This fusion between plant and fungi occurs in the rhizosphere, or root zone. The mycelium forms a sheath-like structure around the root tip that surrounds plant cells in the root cortex. Threads of hyphae—individual strands of mycelium—extend out into the soil where they break down organic matter and even connect one plant to another, forming a biological internet.
Although not genetically part of the cannabis plant, mycorrhizae form a mutually beneficial relationship with cannabis roots that helps both species survive and thrive. These fungi appear all throughout nature and form a fascinating symbiotic relationship with up to 90% of plant species.
Without a doubt, cannabis claims the title as one of the most beautiful plants on Earth—from its glittering trichomes and signature leaves to its complex root system. Many growers frequent their grow rooms just to stand in awe at what grows before them.

Mycorrhizae ultimately act as an extension of the root system. Not only do they break down organic matter to release nutrients, but they also transport these important molecules from areas plants could otherwise not reach. Ultimately, mycorrhizal fungi play a fundamental role in plant nutrition and soil biology and chemistry.
