As opposed to fan leaves, sugar leaves are small leaves found throughout cannabis colas’ cupping buds that are typically trimmed off the flower after harvest. They are called “sugar leaves” because of the high volume of trichomes found on them, which makes it look like the leaves are covered in sugar. Sugar leaf trim can be used to make edibles or concentrates.
There is one very important reason why it’s crucial to be able to distinguish male from female plants: Only female plants produce flowers. Because male plants produce pollen sacs, they do not generate any of the buds that people actually harvest and consume. From the perspective of growing weed for human consumption, male plants are really only good for propagating brand new baby plants from seed.
The flowers of the female marijuana plant can be identified by their small teardrop structures, which consist of pistils attached to bracts. Cannabis flowers are usually covered with a frosty-looking coating of trichomes, with a heavier density of trichomes making for a more desirable flower.
The main part of the flower, at the end of a female plant’s stem is composed of many small floral clusters. In general, the bigger, heavier, and more densely covered in trichomes a cola is, the better quality it will be, although some cultivars will naturally grow flowers that are more loosely structured and airy.

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.

After liberating nutrients from the substrate, the mycelium uptakes and shuttles them around to plants. Because cannabis roots aren’t capable of this impressive function themselves, they have to “bargain” with the mycelium to access these nutrients. Luckily, plants produce sugars during photosynthesis, and transport many of these molecules down into the roots. Here, they swap these energy-rich exudates for the nutrients they need to fulfil important physiological functions.
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.
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.
