For example, it has been shown that colder temperatures can accelerate the flowering process. During colder months, the plants will also produce denser flowers as well as vegetables and fruits with a higher sugar content. Different strains of marijuana will all have different flowering times, so it's best to research the strain you're planning on growing to know when to expect flowers and prepare for harvest.
Growers can control the different factors that cause a plant to flower regardless of the season. Known as flower forcing, this technique is commonly used in larger agricultural crops and involves adding nutrients such as plant growth regulators and bloom boosters.
During the flowering stage, a cannabis plant's demand for potassium shoots way up, which is why many bloom boosters on the market contain high levels of potassium. The K in N-P-K.

They still develop in pairs but there is more distance between them and branches are no longer parallel to one another.
There are also secondary nodes on branches that have developed from the main stalk. Sativa plants are lanky and don't have as many leaves while Indica plants are shorter and denser.
During the vegetation stage, it's important to increase water to aid in the plant's development. As your plant grows larger and the roots grow outward, it's better to water farther away so that the tips of the roots can more easily absorb it. During this stage your plants need an increase in warm water, a flow of dry air, nitrogen and potassium-rich nutrients, and a lot of soil space to allow them to grow feet tall.
Similar to the seedling stage, during vegetative growth, cannabis plants should be in well-drained soil. It's important to let the plants dry out between watering to ensure they do not drown. The growth of the plants is based on the rate leaves gather light and transform it into photosynthesis. For indoor grow rooms , plants should be kept on an hour day light cycle with a 6-hour night period. You can keep your plants on a hour light cycle but plants tend to do better when given breaks and it will save you some money.
Fun fact: Since light cycles control when a plant goes from the vegetative stage to flowering, they can be kept in vegetation forever. This is a tactic used to skip the germination stage and grow plants from cuttings.
Pre-flowering It can take anywhere from 7 to 14 days for a plant to enter the pre-flowering stage. Once it does the sex can be determined by the pre-flower found at the nodes.
It becomes easier to figure out the sex when the plant goes deeper into vegetation. How to tell if your plant is a male or female Female: Two pistils the pistil contains the reproductive parts of a flower will be growing on the buds flowers grow above these leaves, one cluster on each side.
Male: Small green sacs full of pollen will be seen on the node areas. Once the sacs on a male or intersex plant burst, the pollen can fertilize the cola of nearby females ruining the psychoactive potential of their trichomes small glandular hairs.
This is why it's critical for male and intersex plants to be removed before flowering. Since Hermies have both glands and leaves the reproductive organs of a cannabis plant , they can pollinate themselves and ruin your harvest.
You must remove and destroy all intersex plants because of this risk. A cola is the flowering site on a female cannabis plant where flowers grow together tightly. This is also known as the terminal bud. Healthy plants typically form one main cola from the center of their structure and smaller colas form on the outside of the plant. Trimming and training are used to increase the number of large colas a plant will form.
Non-pollinated female plants produce Sinsemilla, they have no seeds and produce more cannabinoids. Sensimilla has an exceptionally high concentration of psychoactive agents and is responsible for effects like talkativeness, increased sociability, euphoria, the munchies, and hallucinations. These plants produce large volumes of resin and fake seed bods both containing high levels of THC.
Sinsemilla is identified by the white hairs that sprout from the bracts at the plant's nodes. Once the plant starts receiving less light per day from 18 to 12 hours , its growth will halt and it will enter the flowering phase. Flowering The flowering stage occurs naturally when plants receive less than 12 hours of light a day. For cannabis to completely enter the flowering stage it requires periods of 10 to 12 hours of complete darkness.
You will know that your plant is ready to be harvested when the colors of the pistils on cola buds turn from white to reddish orange and the trichome heads turn from transparent to milky to opaque and finally amber. Trichomes produce THC, terpenes, flavonoids, and other cannabinoids. As flower clusters develop more cannabinoid compounds develop and the clusters become sticky from resin.
In the flowering stage, cannabis plants enjoy warm weather, medium humidity, and benefit from intermittently receiving blooming nutrients. If you notice that the trichomes fell off, you let the plant grow too long and most of the cannabinoids are gone meaning you won't get the THC or CBD effects and will have to start over with a new batch. Trichomes turn from cloudy white to brown once THC begins to weaken.
While having some brown trichomes is okay, its a sign that the plant is ready to be harvested. Those that flush their plants often provide only pure water for the last week or two before harvest.

Growers often harvest when the majority of the trichomes are cloudy. But personal taste may dictate an early, mid or late harvest. Each has their own effects, pros and cons.

In simple terms that means re-growing the plant after harvest. Just leave some green leafy material and lower buds on your harvested plants.
This allows them to gather light energy when you put them back in the grow room with hours of daily light. Wait a few days you will see new vegetative growth. Most people take cuttings from plants in vegetative growth. But you can also take a cutting from a plant which is already in the cannabis flowering stage. These can be reverted back to vegetative growth for a few weeks before flipping into bloom. You have successfully germinated your cannabis seeds and grown them through the veg growth stage.
Now you need to successfully and safely get your plants through the cannabis flowering stage without any mistakes. Here are some of the most common problems to avoid.
Maintaining a good, stable climate will prevent many subsequent issues. Avoid large swings in humidity, keep RH low during the cannabis flowering phase and monitor with a hygrometer to record daily minimum and maximum readings to avoid any major humidity swings after watering and overnight. VPD and the theory behind it can seem complicated to grasp, especially by less experienced growers. All pH and EC meters should be regularly checked and recalibrated against known reference solutions.
If you get pH and EC wrong it can have damaging effects. Get them really wrong and it could have fatal consequences for your plants especially in hydroponic grow systems. Related: Understanding how pH affects cannabis plants. Serious growers pay very close attention to their light levels during the cannabis flowering stage. Take time to understand the PPFD light levels you are getting at various hanging heights over your grow area. The best light manufacturers will clearly show the lights intensities produced by their lights at different hanging heights.
Understanding correct light set-up will ensure that you can gradually increase your plants exposure to steadily higher light intensities as they mature. PPFD light levels of around are often used in the cannabis flowering stage. Raising your light further above your plant decreases the intensity of the light energy they receive.
Putting your light closer to the plant canopy increases intensity. One thing you can be sure of when growing good quality cannabis seeds is that you will have a pungent grow tent during the cannabis flowering stage. Not paying attention to the smell, and not dealing with it effectively is a recipe for problems. The attentive cannabis grower uses a good quality carbon filter to remove smells and may even keep a spare one ready for the time when the filter fails.
If seen, male plants are usually quickly removed from the grow room and discarded to prevent them filling your precious buds with seeds. Another cause of pollinated female plants is if one of your plants turns hermie during the flowering stage of cannabis. Isolated hermie flowers can be removed individually. When all common mistakes are avoided light burn, nutrient burn, pH issues, stable environmental conditions, etc. For many growers, the cannabis flowering stage is simply the most rewarding and exciting part of cannabis cultivation.
Anticipation grows week by week as the plants mature. The buds begin to stack nicely on each other as the blooms grow in length and girth.
Get the best cannabis seeds you can from a supplier you trust and remember the cost of the cannabis seed is small in relation to the value of your final harvest.
