Buds will not have grown too much at this point, so don’t worry if they are still fairly small.

Flowering is triggered by the light cycle shifting to 12 hours on and off, so the timing of it will vary from grow to grow but this generally begins around week 13 of a grow.
As the taproot of the germinated plant begins to take hold, the first set of iconic fan leaves begin to develop. This signals the beginning of the plant’s seedling stage of growth and should be placed in a large growing area immediately if it hasn’t been done so already.

After those initial leaves develop the plants begin to enter a stage of explosive growth. This is the vegetative stage. A healthy vegetative stage is the period of growth most associated with great yields, as the size of the plant can make a huge difference at the end of it all.

This is also the stage with the greatest variability for the length of time it will take to get through, dependent on strains and growing conditions.

Sexing can technically wait until the flowering stage, but cautious growers should remove them now.

You can observe the quality of the seed by its color and texture. The seed should feel hard and dry, and be light- to dark-brown in color. An undeveloped seed is generally squishy and green or white in color and likely won’t germinate.

Different stages call for different amounts of light, nutrients, and water. They also help us decide when to prune and train the plants. Determining a plant’s sex and overall health rely on stages of growth as well.
There are a number of changes to consider once your plant goes from its vegetative stage to flowering:

The first stage of life for a cannabis plant begins with the seed. At this point, your cannabis plant is dormant, patiently waiting for water to bring it to life.
Generally speaking, it takes anywhere from 14-32 weeks, or about 4-8 months, to grow a weed plant.
Light cycle: 18 hours of light
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.
Vegetative plants appreciate healthy soil with nutrients. Feed them with a higher level of nitrogen at this stage.

Light cycle: 18 hours of light

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