how long does a cannabis plant take to grow

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.

Vegetative stage length: 3-16 weeks

Important dates for growing marijuana outdoors

The first marijuana plant stage begins with the seed. A cannabis 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.

Seedling stage

Seed germination length: 3-10 days

Many other breeders also produce great auto-flowering strains (Dutch Passion, FastBuds, Barney’s Farm, etc.), but the following breeders stand out for consistency.

Auto-flowering plants tend to stay small since they go from seed to harvest in under 3 months. These auto-flowering plants produced about 7 ounces.

Long Anwer:

Strains from warm climates tend to have long flowering periods before their buds are ready to harvest, adding weeks or months to the time needed. Long-flowering strains often produce higher yields than short-flowering strains because buds have more time to grow. For example, Acapulco Gold takes almost 3 months after initiating 12/12 before buds are ready to harvest. However, it produces amazing yields and unique psychedelic effects.

2-3 months from seed to harvest

Depending on how you set up your grow, it can take anywhere from 2 months to 6 months or more to grow a marijuana plant from a seedling to the point where the plant is ready to harvest. Some methods, such as growing hydroponically indoors, give your flexibility to get a harvested plant in as little as 2-3 months. Growing outdoors generally takes longer than growing indoors and is more dependent on when you plant your seeds and how long your growing season is.

Curing weed eliminates the grassy smell and harsh flavor of dried buds. It also reduces the head rush aspect when smoking the buds, and makes them better at reducing anxiety, pain or feelings of depression.

Growing from clones instead of seeds speeds up the process a bit, since the clones are already fairly well developed. You have to wait for them to root, but once they do, you have a huge head start over a seed.

Time Required: 3 to 7 weeks

Note that low moisture content in the air can stunt growth and lead to longer vegging times, so you might need to raise humidity levels in your grow tent. Vegging time also increases every time you top your marijuana plants.

The amount of time it takes to grow cannabis can vary greatly, but there are things you can do to speed it up. Some, like shortening the vegging time, will have negative effects on yield, so you should always weigh the options carefully.

The primary factor that influences how long it takes cannabis to grow is the strain. Choosing a fast-growing strain can shorten the time considerably.

Use A Separate Veg Room

Our simple guide to growing marijuana covers everything you need to know.

How much time it takes depends on a number of factors. That means it is not possible to give an exact time frame. It also means you can speed up the time it takes a bit.
