    Very nice! Good visuals, and a good explanation for each stage of flower.. thanks!

  2. @NiSiochainGanSaoirse on October 25, 2025 at 5:35 pm

    Always wait for the buds to swell before harvesting.
    Just as the trichomes begin to get milky rapidly, the buds swell as the calyxes open.

    Mine are doing this right now, and im gonna leave them two weeks.

  3. @holyn8 on October 25, 2025 at 5:36 pm

    i didnt knew you could give them LESS than 12 h light.. how much less? will it flower faster?

  4. @bigmilk2003 on October 25, 2025 at 5:36 pm

    thanks for the info, with a plant that is 5 inches tall I was worried that it would not get much taller

  5. @dougtheslug6435 on October 25, 2025 at 5:37 pm

    The plants go into flower when the light cycle starts to go down a few weeks after the max peak sometime in August, not 12 hours in my view. I’ve been growing outside for a lifetime and to reach 12/12 in light would mean December sometime and we all harvest in late September way before it ever gets to 12/12. In a tent you go for 12/12 because it gets the plant there faster and you can cycle in more grows all year, that’s all.

    I know someone who is going threw the flower stage but they are not really stretching do u know why this is

  7. @riodejarnett on October 25, 2025 at 5:37 pm

    I need to hear about the pH during flowering. Should I really hit him hard with the acid??

  8. @branjosnow6244 on October 25, 2025 at 5:41 pm

    Trichomes will turn amber on the sugar leaves pretty early, so make sure you’re looking for the first ambers on the bud itself. Or you’ll harvest far too early.

  9. @vashman01 on October 25, 2025 at 5:45 pm

    I started 4 seeds from the same strain at end of March. As of mid May, 1 of them has gotten about 4 feet tall and went into full blown flowering stage. What the heck happened? All 4 have been grown together in the same conditions.

  10. @JayDillDrums on October 25, 2025 at 5:47 pm

    Are use organic living soil and just top dressed some organic amendments as needed.. It’s been my favorite way to grow! Finish off the last few weeks with the homebrew compost tea

  11. @kevinemard5370 on October 25, 2025 at 5:47 pm

    When is the best time to begin the flowering stage?

  12. @mathewpinny6872 on October 25, 2025 at 5:48 pm

    Great video your very helpful 👍…its my first grow and time to flower.😁…exciting and torture awaiting the outcome give me a buzz might become a passion and inspiration for me.❤…always top level dude appreciate what you do.🤗

  13. @TOR_bbk on October 25, 2025 at 5:48 pm

    So the first day of flowering is thw day the light cycle change?

  14. @TheeThunderGod on October 25, 2025 at 5:50 pm

    Ur plants aint getting enough nutes. I see a few deficiencies going on, especially nitrogen. Ur either not feeding them enough, ur nutes aint strong enough, or u have nutrient lockout from either overfeeding or ph is way off. Looks like u used Miracle Gro Bloom which i use too so its definitely strong enough but i grow in Soilless hydro mix with coco in it. If ur using regular soil then u definitely have a lockout. Miracle Gro can leave salt/nute build up in ur soil over time. Water with plain water once a week to prevent this. Flush the soil with plain water to correct this. Next time, wait until ur plants are very healthy WHEN u flip to flower. Ur yield ans quality could’ve been quadruple what u ended up with. Keep growin’😎

  15. @holyn8 on October 25, 2025 at 5:51 pm

    3:50 i wonder why not more people breed their own seeds. my plan is to get really nerdy on this. any tips?

    My purple Kush showed flower after 5 days into 12 12

    Thank you for keeping it simple! Peace ✌️ ☮️

  23. @JayDillDrums on October 25, 2025 at 6:00 pm

    I’m so glad to see somebody who is halfway through flower and the plants aren’t DEEEP green. if your plans are super dark green and your anywhere past day 30 in flower, I would say you already have too much nitrogen 😊

  24. @jonhoward9697 on October 25, 2025 at 6:01 pm

    Is this Hamilton narrating this?

    OUTDOOR LIGHT DOESN’T REACH 12/12 UNTIL LATE SEPTEMBER CANNABIS START FLOWERING WSY BEFORE 12/12 😂😂😂 OBVIOUSLY THIS RETARD NEVER GREW OUTDOOR A SINGLE TIME

  27. @billygoat520 on October 25, 2025 at 6:06 pm

    After twice flipping my lights a little late my plants grew too tall, this grow I went much earlier to better allow for the phenomenal stretch loaded with buds. I topped right after the 5th node as well in the same effort.

  28. @TopoftheSouthPacific. on October 25, 2025 at 6:07 pm

    12/12 light cycle year around here

  29. @pullordienow8392 on October 25, 2025 at 6:08 pm

    Some amazing imagery and awesome explanations here!
    Good stuff!

    I live and grow outdoors in the subtropics, a day south of Puerto Vallarta. Ignorant American growers (not stupid, just without information) perpetuate the myth of 18/6 veg and 12/12 flower cycles. If you are growing indoors, that’s fine. I just want to say that many of my outdoor plants start flowering at 15/9. I am harvesting now. Days are 12.3, nights are 11.7 as of September 8. I only have one stubborn plant which has not gone into flower. Most are curing in glass jars.

    Of course, this will depend on the strain and other factors. But the myth of ALL cannabis plants needing 12/12 before flowering begins shows a lack of experience, at least for outdoor growing. This observation is NOT to put anyone down. I have watched a lot of videos to learn from other peoples experience. I will harvest about 8 pounds from this current crop. Over 80% had started flowering at 13.5/10.5, day to night ratio. Maybe my experience will help you. Thanks for your otherwise flawless video.

  31. @Light4209_ on October 25, 2025 at 6:09 pm

    Thank you boss man! About 1 week out from flower time.

  32. @juliangrove7441 on October 25, 2025 at 6:10 pm

    Fascinating vid. thank you for that. I will harvest at 30% amber tricomes as opposed to what I was doing before at 70% amber. I have 3 plants on the go and have no weed available until harvest time in about 5 weeks. To chop it earlier has made my day.

  33. @MOSP14 on October 25, 2025 at 6:13 pm

    Hey Flint, I hope you’re doing aight, sorry for your dad’s death…

  34. @bertjesklotepino on October 25, 2025 at 6:14 pm

    this may be a stupid question…
    But i planted one in a big round tub which you use to mix concrete.
    And it is on the patio. It has grown nicely, and is now forming the flowers.
    It is a nice plant in my opinion. As a noob to this stuff.

    I have regularly spend time on the plant, to check and do stuff.
    I notice that one side has thick branches, and the other side has thin branches.
    Mostlikely because one side was in the sun all day long until evening, and other side is the shadow side.

    I have twisted the plant a bit from time to time.
    From left to right, north to south basically.

    So my question is this:
    When i grow a new plant, would it hurt the plant if i was to twist it daily, from north to south and back to north again.
    So basically what i mean is: What if i was to turn it around on a daily basis. So 180 degree turn. So one day one side gets the full light, the other day the other side.
    Would that hurt the plant?
    Or would it make all the branches the same thickness and give them the same potential?
    Because with the plant i currently am growing, it is noticable that the thin branches are not producing the best flowers. They are nice, and i dunno if i should keep em or not…… they might be a few nice flowers.
    But i have no clue if it would benefit the other better looking flowers if i were to chop em all off. NO clue what stage you should consider doing that, if i am too late for it or can still chop em off. If it will benefit…. i have no idea.
    I am just trying.
    And in my opinion it does look like a nice plant.
    The stem at the soil level is like 2 inches in diameter.
    Its a trunk. Good root system, some visible above ground.
    Thought about covering em up with new soil, but it is already in flower stage. How much would that benefit the plant?

    I am using regular feeding stuff from the store. Food for green plants, i dunno how you wanna call it. 7% Nitrogen , 4 procent P2O5 and 6 % K2O
    Central Park is the brand, for all indoor plants, green and flowering.

    Yes: i did plant my indoor plant outside in the sun.
    Yes, i do use indoor plant food stuff liquid crap, for green flowering plants.
    Seems to work ok up to now, the flowers do look healthy, smell nice, grow fast, etc.

    Anyways, if anyone has any tips, especially if it benefits this plant to turn it 180 degrees on a daily basis, or if that is gonna kill it in flower stage?
    Would be much appreciated.

    So does this apply to living soil? With the bloom nutes?

  42. @tommiemarsh9006 on October 25, 2025 at 6:23 pm

    Stop feeding 30 days before harvesting. Or smoke
    plant food and get sickness!

  48. @Probleme5 on October 25, 2025 at 6:28 pm

    I posted this in a few places no one knows. My friend has a budding problem, budding too early. This happened a week before planting outdoors and noticed early buds with only 3 leaves on the plant. It had morning sun for over 6 hours for 7 weeks. It’s about 8 weeks old now. Should he cut the early buds out or leave them alone?

  49. @josephspagnola9884 on October 25, 2025 at 6:30 pm

    Does anyone trim leaves while they are budding?

  50. @sampatterson7761 on October 25, 2025 at 6:31 pm

    How much litres per day per plant ?
