Cannabis plants grow, flower, set seed, and die within a year. The flowering stage typically spans six to twelve weeks for medical cannabis and other common cannabis varieties. It is important to understand the three stages of flower development: early, mid, and late flower.
During the vegetative stage, cannabis plants often thrive on an 18/6 light cycle (18 hours of light and 6 hours of darkness). Once flowering, the plant must return to a short period of vegetative growth to regrow more branches and leaves in preparation for a new flowering stage.
The flowering stage can take anywhere from a few weeks for certain autoflowering varieties to several months for photoperiod strains. To optimize your cannabis yield, it is recommended to time the switch to bloom nutrients to coincide with the onset of flowering.
In the flowering stage, the plant continues to grow, usually doubling or tripling in height depending on the strain. It is essential to provide growing nutrients for at least one more week once flowering starts.
Cannabis plants are photoperiod plants, meaning they initiate the flowering process in response to changes in light exposure. The stages of cannabis growth include germinating (1-7 days), seedling (2-3 weeks), vegetative (2-8 weeks), pre-flowering (1-2 weeks), and flowering (6-8 weeks).
In summary, cannabis plants grow, flower, set seed, and die within a year. Understanding the stages of flower development, transitioning, caring for, and harvesting is crucial for optimal yield.

How long does cannabis stretch in a flower?
Cannabis strains typically stretch for the first two weeks of flowering, with some strains continuing into the third or fourth week. Sativa strains stretch more than indicas, potentially doubling or even triple their height during bloom. Plant hormones, influenced by daily light hours, initiate cannabis flowering stretch when plants sense a reduction in daylight hours. Autoflower strains dictate their own vegetive period based on genetics. Charles Darwin’s theory of plant hormones, which explains plant bending towards light sources, was first developed in the 1890s.
Does cannabis grow taller during flowering?
Cannabis plants typically double their height after entering the flowering stage when lights are switched to 12-12 hours of light and 12 hours of darkness. Some strains, particularly sativa-dominant strains, can triple in height during this stage. Indica strains may not grow much taller during the flowering stage, but may become bushier. It is generally expected that plants will double their height after entering flowering. Long, lanky plants with thin leaves, like sativa, will grow more. Low, bushy plants may continue to grow in the same pattern during flowering. Stretchy, tall plants will stretch more after flowering.
Do cannabis plants continue to grow during flowering?
Cannabis plants enter the flowering stage when they receive longer hours of uninterrupted darkness during the light cycle. This occurs when the days get shorter around the end of summer, while indoors, it begins when lights are switched to 10-12 hours of darkness. The flowering period for most strains lasts about 7-9 weeks, with some sativas requiring even longer for buds to mature. The exact timing and what happens during flowering can vary depending on the strain, so it’s a general guideline rather than a strict schedule.
Do buds shrink late in flowering?
Late-flower (Weeks 6-8) is a crucial stage in cannabis plant growth, where buds begin to harden, trichome heads turn amber, and pistils shrink and become fragile. As plants ripen, new aromas, flavors, and pigmentation develop, such as brown or purple shades. To enhance your crop during late-flower, flush your plants with plain water to flush out nutrient salts that may have built up during its lifecycle. Mineral-based fertilizers are effective, but chemical salts can build up in harvestable plant material, making it unsafe and undesirable.
To ensure the cleanest and most desirable cannabis, growers must flush their plants with access amounts of clean water during the last two weeks of the flowering period. This helps maintain the health and desirable characteristics of cannabis plants.
How much growth during flowering?
The cannabis flowering stage is the final stage of a plant’s growth before harvesting, involving the development of flower buds. High-quality buds can be harvested after 7-9 weeks. During this stage, plants double their height and divert nutrient supply from leaves to develop flower buds. The production of resinous trichome glands also takes full flow, producing a sticky, aromatic resin coating the buds.
The onset of the flowering stage is triggered by changes in photoperiod or environmental cues, with photoperiodic strains transitioning from vegetative to flowering in response to decreased daylight hours.
Stable environmental conditions, proper nutrient balance, and precise light cycle manipulation are crucial for successful flowering initiation. Optimal temperature and humidity levels promote robust growth, while nutrient adjustments, particularly reducing nitrogen levels, are crucial. The cannabis flowering stage typically lasts 6 to 12 weeks, influenced by strain genetics and cultivation methods. Indica strains typically flower for 6 to 8 weeks, while sativa strains may take 10 to 12 weeks.
Advanced breeding has led to autoflowering strains with rapid flowering in 8 to 10 weeks. Monitoring trichome development and pistil coloration helps determine optimal harvest time, aiding growers in optimizing cultivation practices for desired yields and quality.
How do you know when cannabis is done flowering?
Cannabis plants are ready for harvest when their pistils on cola buds turn from white to reddish orange and trichome heads turn from transparent to milky to opaque, ultimately turning amber. This indicates a higher CBD to THC cannabinoid ratio in the resin. Cannabis growth involves a series of stages, each requiring unique demands like light, water, and nutrients. It can take 4 to 8 months to grow a cannabis plant, depending on the location. Indoor grow rooms allow for complete control over environmental conditions, allowing plants to flower within weeks.
How long can cannabis stay in flower?
The period required for cannabis to reach maturity varies according to the specific strain and cultivation method employed. In general, this process takes between six and 12 weeks following the flowering stage.
How long does cannabis stretch in flower?
Cannabis strains typically stretch for the first two weeks of flowering, with some strains continuing into the third or fourth week. Sativa strains stretch more than indicas, potentially doubling or even triple their height during bloom. Plant hormones, influenced by daily light hours, initiate cannabis flowering stretch when plants sense a reduction in daylight hours. Autoflower strains dictate their own vegetive period based on genetics. Charles Darwin’s theory of plant hormones, which explains plant bending towards light sources, was first developed in the 1890s.
Do roots continue to grow during flowering?
During flowering, plants develop roots slowly, requiring optimal conditions for large buds. Root rot or lack of water can lead to reduced yields due to reduced nutrient absorption. Enzymes can help address this issue by reducing soil salinity and promoting relaxation. Flushing cannabis plants is essential for harvesting high-quality buds without excess nutrients, which can affect taste and smell. Using mineral nutrients and enzymes can also help reduce soil salinity and improve yields. Flushing cannabis plants is a simple process that ensures optimal growth and yields.
What does week 1 of flowering look like?
In the flowering stage, calyxes form and pistils (white hairs) emerge from the same locations. Maintain a temperature of 78-82°F/26-28°C during the day and 62-70°F/17-21°C at night, with relative humidity between 50 and 60. For beginners, aim for 50-60. In week two, white hairs multiply and spread quickly, marking bud growth. If the plant is male, it will grow pollen sacs instead of white hairs.
Will buds grow during flowering?
During the flowering stage, weed plants develop buds and trichomes, which are crystal-like formations on the buds’ surface. Buds are rich in cannabinoids like THC and CBD, while trichomes are crystal-like structures with terpenes that contribute to the plant’s unique flavor and potency. To ensure optimal growth, plants need twelve hours of light followed by twelve hours of darkness daily, mimicking the natural transition to fall.

Hello, I have been checking my plants (outside) with a loupe. They trichomes are cloudy but 30% have not turned amber, although I think they are only days away. The colas are really large and I am intrigued (first year – total novice. This has been more of a gardening project. My husband smokes, I don’t). We are supposed to get a frost tonight. Should I cut? Sorry; thank you! Also, the only place we have to dry them is in the basement and I’m afraid they are going to smell up the house bad. We can smell them all over the yard even though they are in a small area.
It’s great how he reminds me of my chemist teacher. I don’t want some homey teaching me about it, it’s a scientific matter that deserves some professionalism. And no he didnt say look for amber color blablabla, thats what your homey will tell you. Thanks for clarifying Dr. DeBacco, brief but very to the point.
I have been growing on my own with little advice or help and use articles like yours to learn how? lol I have been growing in my veggie garden for years. Last year i would have had the best crop i would have ever grown in 8seasons of trying, but i have afids tear my plants up,basically over night!?!I had checked them on a friday after work, and was watering with a sprinkler. I took a look at them again on a sunday morning,early and they had looks almost grey or brown from a distance…? I got up to them and there were thousands of afids all over the buds of the plant! They have tore up every last buds and deficated all over the plants! :>( So this year i have used some all natural insecticide and the buds look ggreat and no afids this year! :<) My issues is being able to know when the perfect time is to harvest? I watched a few articles last night and had decided to check them today. They looked like they were ready and even with the magnifying glass it is very hard to see the damn trichomes??? I had to manuver the plant in such a way to get direct sunlight on them to see them? The leaves and every bit have a white haze but only about 50% of them are mature.....:>/ I couldnt tell until i got it inside and was able ot take an even closer look? I guess its time to invest in a better magnifying glass?lol I did just pull the plant and have it hanging right now. But is it best to trim the plant now while its fresh or wait until its dried before trimming? HELP?LOL
There is an alternative to light TIMING. I grow the MOST plants by running 18 Hours of full spectrum light at 18 hours on and then 6 hours of only BLUE light. Veg Growth is RADICAL!!!!!!!! For Flower I do 18 hours of full spectrum and 6 hours of RED LIGHT only and the flowers Explode with dozens of Buds in the first 10 days. This is how you get 180 Grams of buds per plant in 9 weeks. Forget about TIMING and instead play with the NM of the light frequency.
I SCREWED UP!!!!! I even wore my glasses and used a lighted magnifying glass and went out at noon to use the sun in the aid of it. My eyesight is getting so bad i thought it was ready? I believe i picked it a bit too soon. It is the, middle September but i should have left it until the end of the month ……maybe? Plenty of tricombs and a good number all over the plant has its mushroom like top and all fully errect on 90% of the plant. Near the tops of each stalk as im growing outdoors in a garden,and top my plants for multiple buds/tops. the top buds at the top of each stalk has some that were just starting to bend over a bit but still had a number just forming. The lower buds near the middle and lower parts of the plant all had a white haze and so on lol but I think if i would have waited til most were starting to bend over and turn a bit dark it would have been better…….no?
Well the article does not give any info about visually timing the peak harvest but just very general what parts of the plant are female and associated to bud growth…very general with little to zero information just as all the articles ive watched from this websitel…nice background information for absolute beginners but not piece of advice to be found
