We can’t stress enough that the timeframes in the above graphic are ranges of time for the Northern Hemisphere. You’ll need to adjust them based on your specific region and local weather and climate.

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.
Vegetative stage length: 3-16 weeks
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.
The first phase in your cannabis plant’s life is germination. During this process, your seed will form its first taproot and emerge into a seedling. Germination requires three specific factors: darkness, humidity, and moisture. Together, these elements will activate your seed. It just so happens that soil provides the perfect venue!
Your plants have entered the flowering phase. As the fall equinox approaches, the days begin to get shorter, and plants get the signal to blossom. Tidy them up and make sure each bud site has an adequate amount of light exposure.
To germinate your seeds, poke a hole into the topsoil in a garden bed or pot. Place the seed in the hole and gently cover with soil. Add a little water. You’ll see the first shoot emerge within 2–7 days.
Pots allow growers to easily move their plants to safety when conditions get rough. Smart pots and air pots also help to minimise fungal infections and keep root systems aerated.
If you live in a warmer climate, now is the time to germinate seeds directly outside. You’ll also be able to move indoor plants outside and transplant them into soil or larger containers.
