Often, growers will top, or cut off, the stem after about five nodes, which forces the plant to grow out laterally more, creating more bud sites.
Cannabis is a dioecious plant, meaning it can be male or female, and the male and female reproductive organs appear on different plants. What’s in your stash jar now are the flowers of a female marijuana plant.
Male cannabis plants grow pollen sacs instead of buds. Male plants are usually discarded because you don’t want them to pollinate the females, which will produce seeds—no one wants to smoke buds with seeds in it.
How to determine the sex of a marijuana 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.
Seeds are produced in female cannabis plants and carry the genetics of a male and female. Seeds need to germinate to sprout and will grow a taproot, which will become the main root that anchors the plant.
A cola, also called a “bud site,” refers to a cluster of buds that grow tightly together. While smaller colas occur along the budding sites of lower branches, the main cola—sometimes called the apical bud—forms at the top of the plant.
Males and females are usually only pollinated when crossbreeding plants or creating new strains.
If you’re growing weed outdoors, it’s great to find a community of cannabis growers in your area to see how others are growing in your specific climate. Local climates vary, so it can be helpful to see what strains thrive where you are, and also when other growers are popping seeds, harvesting, and more. You can also join online forums or Social media groups, but a great place to start is your local grow shop.
There are also commercially available soil blends that already contain the proper mix of these types of ingredients.
Benefits of growing weed outdoors
Heavy rains and high winds can cause physical damage to plants and reduce yields, and excessive moisture can lead to mold and powdery mildew, especially during the flowering stage.
Weed plants will need full, direct sun for at least 6 hours a day. You may have a backyard, but it might not be great to grow there if it doesn’t get full sun every day.
However, plants grown in pots, buckets, or barrels will likely be smaller than those planted in the ground because their root growth is restricted to the size of the container. In a broad sense, the size of the pot will determine the size of the plant, although it’s possible to grow large plants in small containers if proper techniques are used.

Morphological differences in wild and cultivated forms of cannabis have introduced taxonomic uncertainties. Hence, in addition to C. sativa, some scientists consider the genus as including a second species, C. indica, and even a third, C. ruderalis. These two species are also sometimes treated as subspecies of C. sativa.
Cannabis, (genus Cannabis), genus of medicinal, recreational, and fibre plants belonging to the family Cannabaceae. By some classifications, the genus Cannabis comprises a single species, hemp (Cannabis sativa), a stout, aromatic, erect annual herb that originated in Central Asia and is now cultivated worldwide. A tall canelike variety is raised for the production of hemp fibre, while the female plants of a short branchier variety are prized as the more abundant source of the psychoactive substance tetrahydrocannabinol (THC), the active ingredient of marijuana.
