The flowering stage is the final stage of growth for a cannabis plant. This is when plants start to develop resinous buds and your hard work will be realized. Most strains flower in 8-9 weeks, but some can take even longer, especially some sativas.

Even if growing outdoors, a lot of growers will start their seeds inside under an artificial light to help them through this delicate stage of marijuana growth.

As the sun reaches up high in the sky, your cannabis will want to as well. Make sure all of your plants are outside by the Summer Solstice.

At this stage, the plant is vulnerable to disease and mold. Keep its environment clean and monitor excess moisture. Be sure to give it plenty of light.

Vegetative stage

Outdoors, flowering occurs naturally when the plant receives less light each day as summer turns into fall. Indoor growers can trigger the flowering cycle by reducing the amount of light marijuana plants receive from 16 to 12 hours a day.

The vegetative stage of cannabis is where the plant’s growth truly takes off. At this point, you’ve transplanted your plant into a larger pot and the roots and foliage are developing rapidly. This is also the time to begin topping or training your plants.

Within the flowering stage, there are three subphases:

Seed germination

If you need to determine the sex of your plants (to discard the males), they will start showing sex organs a few weeks into the veg stage. It’s imperative to separate males so they don’t pollinate the females.

Seedling stage length: 2-3 weeks

The quality of your plant depends on your knowledge of the cannabis growth stages and the lifecycle of your plants.

How to tell if your plant is a male or female

Even if you live in a jurisdiction where marijuana is legal, there are age restrictions and your child can end up on the wrong side of the law. You should prepare to have a conversation with your child about the risks involved in using or selling marijuana when underage.

Forty-four percent of all students have tried weed by 12th grade according to the National Institutes of Health.   That means that your child probably has friends who are smoking marijuana or at least know someone who is.
