Flowering Cannabis: Week by Week Guide!

Week-by-week Flowering Stages

Treated well, looked after and well fed, cannabis plants will grow vigorously.

In fact, they grow so well that on a week by week basis, you can see clearly visible changes as time passes.

This continues once the plant begins to flower, and we thought it would be a good idea to run through the weekly stages of flowering for you.

Flowering usually begins once your plants begin to enjoy longer periods of uninterrupted darkness.

From here on in, your plants will begin to put all their energy into producing buds rather than growing.

Flowering should begin when you switch your lights to between 10 and 12 hours of darkness.

Obviously with so many different strains of cannabis, there will be some variations in the flowering period, but you can take all this information as a guide.

In general terms, the flowering period will last for between seven and nine weeks.
In weeks one through three of the initial flowering phase, your plant doesn’t stop growing and buds miraculously appear.

Instead, you may well witness your plant undergoing a growth spurt and some varieties will double in height in the three-week period.

Take note that while this is still recognized as the early stage of flowering, your plant or plants will need plenty of nutrients, so now is not the time to be stingy.

Come week two and you may notice the appearance of small white pistils on female plants. These fine white hairs will ultimately turn to buds. In a male plant, these hairs don’t appear, but instead the plant will produce pollen sacs.

By week three the growth spurt will begin to slow down and you may begin to see signs of your first buds. It’s like becoming a parent for the first time if you are a cannabis plant virgin.

Week four and all plant growth will have stopped, and while your buds will develop white hairs, they should become noticeably larger as well.

Week five will see your buds become thicker, while new buds may start growing along the plant’s cola. You should also notice an intense but pleasant odour coming from your plant or plants.
Weeks six through eight will see the build-up to harvesting.

This is a good time to consider ‘flushing’ your plant – eliminating the nutrients and providing only water.

The trichomes on your plant may start turning a milky white, and as your plant nears the perfect harvesting time, the thrichomes will turn an amber colour with an opaque clarity.

Once you r trichomes are the perfect colour, get harvesting, as it is at this particular point the THC levels in your plant will be at their maximum.

    Love this video lot of information in short time

  2. @Evolve_Bodyboards on December 25, 2024 at 1:58 am

    Your advice regarding the glandular trichomes being at their peak in THC when amber is incorrect. The amber colour in the trichomes is when they have begun Oxidising and that is the degradation stage. This is where THC levels drop and it converts into CBN (sedative)

  3. @santoslabel5943 on December 25, 2024 at 1:58 am

    I had 3 harvest already I look at the trichomes to be an amber color as well letting the leaves turn yellow just a bit before harvesting

  4. @mizhempiana3138 on December 25, 2024 at 1:59 am

    By the time the trichomes are amber the THC starts to degrade… that’s my only issue with this informative video… the more amber the trichomes the less the THC.

    Thanks bro

    Do u feed plant food to budding pot plants

  8. @dimuthuherath9033 on December 25, 2024 at 2:03 am

    My weed plant now 4months old.but no flowering. Why is that?

  9. @laskej81 on December 25, 2024 at 2:05 am

    It isn’t helpful to animate the pistils the exact same as the trychomes. They aren’t the same so it just seems lazy. Thanks for your effort though!

  10. @growingwithjoy on December 25, 2024 at 2:05 am

    You guys should also mention males more in detail for beginners that watch this and are not aware!

  11. @rudolphdumervil9540 on December 25, 2024 at 2:05 am

    TCE where can I get some free seeds?

  12. @ralphyjunior7226 on December 25, 2024 at 2:06 am

    Is there any videos that talk about hermaphrodite and the plant life cycle.

  13. @RestofNature on December 25, 2024 at 2:07 am

    😮😲😳🧐😏

  14. @StolzerSoldat86 on December 25, 2024 at 2:10 am

    So flowering occurs when you put your plants in the dark ?!

  15. @lsheppard8996 on December 25, 2024 at 2:10 am

    Thanks for the vid G. Keep up the work. There needs to be more informative vids like this around.

    Child-like animation? Really?

  19. @sativadiva3771 on December 25, 2024 at 2:13 am

    Let me guess… You don’t respond to your subscribers comments?

  20. @Hipsters_N_Hippies on December 25, 2024 at 2:14 am

    I wouldn’t consider 8weeks enough time, only the very few fastest will be ripe by then.
    I would only start flushing week 8, then start looking at 10-11 weeks for harvest.

  21. @GlobalGhostOps on December 25, 2024 at 2:14 am

    The most simple of explanations and teaching that will help new growers like myself 👍🏻👍🏻

  22. @JoeBlunt on December 25, 2024 at 2:15 am

    Narrator’s voice makes you trust him like 10000% 😆

  23. @amberhouse8351 on December 25, 2024 at 2:17 am

    Amber colours in tri homes means it is on the level of cbd not thc when it’s pure milky that’s your highest thc level u can get…
    I’m from Aussie & we love our thc over in america ppl leave it till it’s fully medical marijuana which is amber colour.

  24. @RangerDink on December 25, 2024 at 2:20 am

    Even though this is something I already know, the art style makes it so entertaining to watch. Like the infographics show and others.

    1 of my plants are at least 3 weeks old and my other is about 2 weeks old. When could i see if its a male or a female? Can i have 2 growing in 1 pot? This is my 3rd try growing but this is the best growth i had yet

  27. @tonnynguyenvn on December 25, 2024 at 2:27 am

    This is what I need, thank you for the video.

  28. @americanman595 on December 25, 2024 at 2:28 am

    What i would like to know is light intensity ive hurd that run your lights at 3/4 power for the first 3 weeks of bud and then increase intensity to 100 % this is to control the stretch and increase bud size does anyone know anything about this?

  29. @growingwithjoy on December 25, 2024 at 2:29 am

    Super cool animated flower video!!

  30. @slava.meseka on December 25, 2024 at 2:29 am

  31. @memethememestar6934 on December 25, 2024 at 2:34 am

  35. @rasenganpimp on December 25, 2024 at 2:48 am

    This is exactly what I was looking for, just a week by week thing of what I can expect in video form lol

  36. @kreeplok123 on December 25, 2024 at 2:48 am

    Those buds look like pollen sacs lol

  37. @miguelramos4570 on December 25, 2024 at 2:49 am

    Great Video 🔥💨 Thanks for sharing 🤘

  38. @anthonysilva5312 on December 25, 2024 at 2:51 am

    Best explanation on the Internet. No bunch of bullshit stoner science

  39. @DaRealChef on December 25, 2024 at 2:53 am

    In december i will be celebrating my first year growing and by far i
    Would always use a jewerlers loop to look at the trichomes (they look like little white mushrooms)
    I dont like to wait when the trichomes becomes amber because then it least thc psycoactive effects
    Id suggest to harvest it when the trichomes are cloudy white
    Have a blessed day peeps🍁🤙🏽
