It is best to be patient and properly care for your plants each day. How long will it take until you’re able to harvest the buds? This subject will be explored in greater depth below.

Factors Determine Growing Time

There are various factors that can determine how long it will take before your cannabis plants are ready to harvest. If this your first time growing cannabis plants, you are in for a treat. Growing marijuana plants has been described by many people as stress-free, entertaining, and educational. Believe it or not, you can learn a lot while growing plants indoors or outdoors but you must expect to encounter a few stumbling blocks along the way. A list of factors that determine growth time is listed below.

Location, Location, Location

It is safe to say that the location you choose for growing your cannabis plants can help determine the length of growth time. You will have two options, including indoors or outdoors. People who reside in closed quarters, such as apartments, flats, and condos oftentimes do not have outdoor space for growing plants. Those individuals will opt to grow their plants indoors but for those who have adequate outdoor space, the latter may be the best option. Those are also those who have outdoor space available but prefer growing indoors because they believe it is more convenient and easier to manipulate the growth cycle.

When cannabis plants are grown indoors, they are not exposed to many of the elements outdoor plants are exposed to. For example, outdoor plants are exposed to dirt, dust, poor weather conditions, and fluctuating temperatures. All of these elements will impact the time it takes for the cannabis plants to mature. Depending on the level of exposure, it is possible to push the growth time back by several weeks.


Cannabis plants need at least 11 hours of sunlight per day. Growing indoors means you have control of how much sunlight your cannabis plants receive. You can manipulate the artificial lighting to slow down or speed up the growth cycle.

Growth Stages

It can take a long time to grow marijuana. During that time, the plant will go through a handful of stages with the last being the flowering stage. Once you’ve reached the flowering stage, you’re almost there. In a matter of weeks, you’ll be able to harvest the buds before you know it. Even then, you should know that the flowering stage may take anywhere from 8 to 11 weeks. With this in mind, it is wise to learn a bit more about the various stages of a plant’s life cycle.


You’ll start with a marijuana seed. Before you can grow that seed, you need to germinate it. This will force the seed to sprout before planting it into the soil. There are numerous ways to germinate a seed. For instance, you can let it sit in water overnight. You can also let the seed sit in a wet paper towel. When you’ve successfully germinated the seed, you will find that one end splits open. And, you’ll notice a white sprout emerging from that end. It can take anywhere from 5 to 10 days for a seed to germinate.


Now, you’ll need to plant the seed. You can do so in a small cup. Or, you can start with a bigger container. Using a small container is fine but you will likely need to transplant it later. You need to water the seedling regularly to ensure it is able to thrive. You’ll also want to consider giving it nutrients. The plant will remain in the seedling stage for 2 to 3 weeks. Then, it will enter the vegetative stage.


This is one of the longest stages of the plant’s life. During the vegetative stage, the plant is going to get wide and taller. If you want to restrict the plant’s growth, you should try topping or bending it. This is a good way to prevent the plant from outgrowing your grow space. You can end the vegetative stage whenever you wish but it will normally last from 3 to 16 weeks.


When you’re ready to enter the flowering stage, you’ll want to change your light cycle. You should switch it to 12 hours on and 12 hours off. Once the plant has entered the flowering stage, it will begin growing pistils and buds. This is the last stage of growth so you’re almost there. You need to know when to harvest the buds. To do that, you need to look at pictures of trichomes so you can time everything perfectly. In general, a weed plant will remain in the flowering stage from 8 to 11 weeks.

Other Steps

After you’ve harvested the bud, you’ll still have to wait a bit longer. Since the buds are still wet, you won’t be able to smoke them right away. Instead, you’ll need to let them dry out first. You can dry them in various ways. However, hanging the buds from a clothes rack is one of the best methods. You’ll need to give the buds a week or longer to dry thoroughly. Growing weed is a long process but it’ll pay off dividends in the long run.

Speeding Things Up

If you’re growing marijuana indoors, you’ll be able to speed up the process slightly. You have control over the plant’s lights, water, and nutrients. So, you will be able to manipulate the environment to your benefit. For instance, you can make the plant grow much faster by giving it 24 hours of light. You can also keep the plant small and enter the flowering stage much sooner. Doing this may minimize your yield but it’ll ensure that you’re able to produce buds much quicker.
