Cannabis Questions Answered – How Long Is The Flowering Stage Outdoors?


The cannabis plant will go through several life stages before the bud will grow. If you’re dealing with male plants, you’ll be able to grow seeds. Either way, you need to learn as much as possible about these stages so you can ready for everything that is going to happen. The flowering stage is the last growth stage and it is one of the most important. Depending on the strain that you’re growing, it will likely be the longest stage too. So, how long will this stage last when growing weed outside?

That is going to depend on several factors. Below, you will learn more about the duration of growing weed outdoors and the flowering stage in particular.

What Is The Flowering Stage?

While it is called the flowering stage, it has nothing to do with flowers or leaves. Your cannabis plants will grow marijuana leaves much easier. This begins in the seedling stage and gets much more prolific during the vegetative stage. Instead, the flowering stage is the time when your plants are going to begin growing buds or seeds. If you’re growing female plants, you’ll get buds but you have to remember that males will produce seeds. Nevertheless, the flowering stage is when the plant begins producing either.

This is the last growth stage. This means that you’ll be ready to harvest the bud or seeds after this stage concludes. Also, it is important to understand that the duration of the flowering stage will depend on the strain, where you grow the plant, and other factors.

Stages Before

Whether you decide to grow outside or inside, it is going to take a long time before your plant reaches the flowering stage. First, you’ll have to go through the germination, seedling, and vegetative stages. If you’re growing cannabis inside, you will be able to switch to the flowering stage when you’re ready by manipulating the plant’s light cycle. If you’re growing weed outside and you’re not working with auto-flowering seeds, you’ll have to let Mother Nature trigger the flowering stage for you.

In general, the germination stage will take about a week. The seedling stage may last as long as 2 to 3 weeks. Then, the vegetative stage can last as long as 16 weeks. With that being said, it can take as long as twenty weeks before your plants are ready to enter the flowering stage. If you’re growing plants inside, you can speed things up slightly. Just remember that doing so may decrease your yield.

Understanding The Flowering Stage

The flowering stage is triggered when the amount of light the plant gets is increased. At this point, the plant will receive 12 hours of light and 12 hours of darkness. This will occur naturally outside since the seasons are changing and the summer days will get shorter. At this take, your female plants will begin developing resinous buds that you’ll smoke eventually. Simultaneously, you should be able to determine the gender of your plants at this point. It is important to do so immediately since you do not want to mix males and females.

Remember to never prune after the plant has been in the flowering stage for three weeks. This could disturb the plant’s hormones and create various problems. It is wise to give plants blooming nutrients during this period. Buds will grow most during the end of the flowering stage. This normally occurs between the 6th or 7th week of the stage. At the beginning of the stage, the plant will grow pistils but the buds will remain small.

How Long Does Flowering Stage Last?

The flowering stage is often the longest stage of all. And, it is the most essential so you’ll need to keep a closer eye on your plant. Again, you should know that the duration of this stage will depend on the strain you’re working with and whether you’re growing inside or outdoors. If you’re growing outside, there is a good chance that your plant will remain in the flowering stage for 7 to 9 weeks. This is the average. During the first week, your plants will begin stretching significantly. They could double in size between the first and seconds weeks.

Then, you will begin noticing the development of white pistils. These will grow near the nodes. This is where the buds will grow in the future. If you’re dealing with male plants, they will not grow hairs. They’ll develop pollen sacs so you can identify them easily. By the fifth week of this stage, you should be able to see the buds getting much thicker. This will continue for several more weeks until you’re ready to flush your plants. You can do so using pH-balanced water.

Also, remember that it is wise to harvest at a precise time. Doing so can help you maximize your bud’s THC content so it’ll be far more potent.

Factors That May Alter Cannabis Plant Growth

Like any other outdoor plant, cannabis is exposed to hundreds of elements, including insects, dirt, pollutants (carbon monoxide, sulfur dioxide, and soot), poor weather conditions, strong winds, and fluctuating temperatures. All of these factors could have an impact on the growth cycle of your outdoor cannabis plants.

Poor Weather Conditions

Regardless of where your plants are located, there is always the risk of bad weather. Heavy rains, blizzards, snow, and hail can do a number on outdoor cannabis plants. Not only can the heavy rains be detrimental to the leaves, stalks, and branches of the plants but also the root system. Cannabis plants only need a certain amount of water, much more than that could lead to root rot. These elements are not of concern for indoor cannabis plants as long as the grower is experienced.

Bad weather for several days could cause alterations in the plants’ growth cycle. In most cases, it will cause the growth cycle to slow down. Fortunately, most cannabis strains are fairly durable, so they should bounce back to health in a few days if cared for properly.

Strong Winds

Strong winds are detrimental to the exposed areas – leaves, stems, fan leaves, cola, trichomes, reproductive organs, and flowers. The force from the strong winds will push the plants from side to side. If you are not careful, the plants could end up leaning to the left or right. While this may not be an issue, it could stunt their growth, pushing back the normal harvest time by several weeks or months, depending on the damage.

There is also the risk of the plants never recovering, which will possibly be the case if the strong winds snap the main stalk in half.
