how long do it take to grow weed outside

The biggest variability in how long a marijuana plant takes to grow will happen in the vegetative stage—after the seedling phase and before flowering.

How long does it take to grow a marijuana plant?

When your marijuana plant becomes a seedling, you’ll notice it developing more of the traditional cannabis fan 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 (3, 5, 7, etc.). A mature cannabis plant will have between 5 or 7 blades per leaf, but some plants may have more.

Seed germination

Marijuana light cycle: indoor—16 hours a day; outdoor—at least 6 hours of direct sunlight (“full sun”), plus several hours indirect sunlight

Determining the optimum location is another important factor that can affect the yield and quality of your plants. Cultivators in the Northern Hemisphere should attempt to place their plants in an area with southern exposure to ensure their plants are getting the most available sunlight. The opposite is true for the Southern Hemisphere.

Organic sources of nutrients include alfalfa meal, bone meal, kelp meal, bat guano, fish emulsion, dolomite, and earthworm castings. Each contains different ratios of nutrients that can be used for different phases of the plants’ growth cycle.

Containers vs. in-ground

During the vegetative stage, water your plants thoroughly, then not again until the top 1 inch (2.54 centimeters) of soil has dried out. This can be every day or every four days, depending on conditions, but the time between watering will become shorter as the plant grows its roots. Container gardens tend to dry out faster than soil beds, so they’ll need to be watered more frequently.

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

You want to get an auto-flowering strain. These cannabis plants automatically start making buds after about a month from germination, and are ready to harvest by the time they’re 2 or 3 months old.

Long Anwer:

You can control the timing if you plan ahead.

Once your plant is harvested, there is a drying and curing process that takes about a minimum of two weeks before your buds are “ready” for smoking. If you aren’t a smoker and plan on turning plants into edibles or concentrates, you should still dry your buds but typically you don’t need to cure your buds.

However, if you take really good care of auto-flowering plants for the first 4 weeks and give a lot of light, they can grow much bigger. These auto-flowering plants reached half this height in the first 4 weeks and produced about 11 oz under the same grow light as above.

Zkittlez Auto is ready to harvest 8-10 weeks from germination. Every time I grow this strain the smell and bud effects are excellent
