These pictures show marijuana, also known as cannabis or weed, in varying stages of growth, processing, and use. You may be concerned about plants you find growing in and around your home. Or, you may wonder whether what you discovered in your child’s room is marijuana or indicates your child may be using marijuana.

You may also find larger quantities of marijuana in a plastic zip-lock bag. You might find smaller plastic bags with residue inside. This can trigger concerns that your child is transporting or selling marijuana rather than obtaining it for personal use.

It may be that your child has experimented with marijuana use or tried it a couple of times with their friends. That happens a lot more these days than it may have happened when you were in school.

How do you do that? The best advice available is the simplest—ask your child.

Parents may want to know what marijuana looks like in all stages of development and use. See photos that can help you check what you find at home.

Buds typically grow the most toward the end of the flowering cycle, around week 6-7. You probably won’t notice much budding out at the beginning of flower, and it will slow down toward the end of the cycle, when buds become fully formed.

Once the buds have reached full maturation, it’s time to harvest.

When your plant becomes a seedling, you’ll notice it developing more of the traditional cannabis leaves. As a sprout, the seed will initially produce leaves with only one ridged blade. Once new growth develops, the leaves will develop more blades (1, 3, 5, 7, etc.). A mature cannabis plant will have between 5-7 blades per leaf, but some plants may have more.

Spacing between the nodes should represent the type of cannabis you are growing. Indica plants tend to be short and dense, while sativas grow lanky and more open in foliage.
The biggest variability in how long a marijuana plant takes to grow will happen in the vegetative cycle—if you’re growing indoors, you can force it to flower after only a few weeks when it is small, or after several weeks when it is big. If you’re growing outdoors, you’re at the whim of the seasons and will have to wait until fall to harvest. The plant will develop buds in the last 8-11 weeks.

To begin growing from a seed, learn more about germination here. This stage can take anywhere between 5-10 days.

It’s important to understand the changes a growing cannabis plant undergoes during its life cycle, as each stage of growth requires different care.
