Marijuana trichomes are hairlike appendages found on the surface of the cannabis plant. Trichomes protect the plant from external stressors and contain resinous glands that create flavonoids, cannabinoids and terpenes — the chemical compounds that give the marijuana plant its unique features and effects. Trichomes give cannabis buds a crystal-like sheen and make them sticky feeling. Within the glandular trichomes, there are three main types: bulbous, capitate-sessile and capitate-stalked. Bulbous trichomes are tiny bulbs that are sparsely located throughout the entire plant, but are so small they can’t be seen with the naked eye.
Capitate-sessile trichomes are more abundant than bulbous trichomes, found on the underside of the sugar leaves and fan leaves, but are usually only visible through a microscope. Capitate-stalked trichomes are shaped like mushrooms and contain a large trichome head at the top of the stalk. These are the trichomes that can be easily seen on the cannabis flower surface. As explained below, nodes are important to be familiar with, as they are where cannabis plants begin to grow either pollen sacs (male cannabis plants) or pistils (female cannabis plants). Understanding the sex of a marijuana plant is crucial to the final product, since only female plants produce flowers and since non-pollinated flowers are far superior than pollinated buds when it comes to consumption. Leaves are important components of a weed plant , and there are actually a couple types of marijuana leaves . The large, protruding leaves that appear along the length of the plant are called fan leaves. Theses leaves are essential to the living plant’s photosynthesis, but are always removed from the finished, harvested product.
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. The main support structure of the marijuana plant , the stem transports fluids, nutrients, and information from the roots to the rest of the weed plant . The stem provides a foundation to give fan leaves access to the light they need to facilitate growth and carries the weight of heavy colas. There is often a lot of confusion surrounding pistils and stigmas, with many people confusing one of the other. Here’s a quick breakdown on the difference between the two important cannabis plant components. The pistil is the primary piece of the female flower’s reproductive system, comprising a single ovule with two protruding stigmas. The thin hairs that extend from a female’s bract to catch male pollen. Knowing how to identify stigmas is an important part of growing weed, as these are the telltale signs that a plant is female and will therefore produce the cannabinoid-rich flowers you’re trying to harvest. Cannabis grows in a variety of climates around the world and can be used in many applications: rope, biofuel, paper, and many medical and recreational uses.

If you want to stay in touch with the origins of your favorite cannabis products, knowing the ins and outs of the plant at the industry’s core is a good place to start. And that includes knowing not only the specific parts of a cannabis plant, but also the different types and strains of weed that exist. Along with understanding the various parts of a marijuana plant, you should also know about the different types of cannabis. While there are long-held claims about the effects that sativas, indicas, and hybrids offer, current research suggests that the effects of cannabis are determined by a person’s endocannabinoid system and the plant-specific cannabinoid profile. Despite that, cannabis is typically classified in the following four categories: Indica: Indica-leaning weed plants tend to produce dense, fat, heavy buds during the flowering stage. These strains are typically believed to give consumers a “body high” instead of a more cerebral high. Sativa : Sativa plants tend to produce buds that are airy and more formed than indica plants. Sativa strains of the weed plant are often said to offer users a more cerebral, energetic, “buzzy” highs. Hybrid : As a blend of sativa and indica, hybrid strains are generally believed to give you a more balanced high. Hemp : Hemp plants are part of the cannabis family, but they differ from a regular weed plant in that they produce only trace amounts of THC, the cannabinoid responsible for the intoxicating effects of the marijuana plant.
In the U.S., the 2018 Farm Bill specified hemp as a cannabis plant containing up to 0.3% THC. However, hemp plants produce a number of other important cannabinoids, most notably cannabidiol (CBD), and their fibers are used to produce a range of textiles.
To break it down even further, there are numerous strains within each of the more general categories indica, sativa, and hybrid. Understanding and becoming familiar with these various strains is what will really enable you to target — on a specific level — the type of experience you have when consuming weed. Typically, you will be able to distinguish between male and female cannabis plants when the plant is about six weeks old. To figure out the sex of a marijuana plant , look at the plant’s nodes, where the leaves and branches connect to the main stem. Male plants will produce pollen sacs that at first look like little tiny balls and then grow into larger clusters of oblong-shaped sacs.
