    How bad is it if one didn’t clean grow space? What if at this point, plants looks super healthy. Should one worry?

  11. Davis Shags on May 15, 2022 at 6:50 pm

    1:52 Holy crap those are some trained plants! Beautiful. Do you have a video on how you did that?

  12. Dale R on May 15, 2022 at 6:53 pm

    Topping or fliming the plants is Idiotic by simply tieing back the main colas you will produce way more bud sites have a even canopy and increase your yield by 40 percent and still have the main colas (L.S.T.) training your plants is by far your best option for Maximum Yield 😎✌️🇷🇺

  13. Daniel Aguiar on May 15, 2022 at 6:53 pm

    At night do u leave the fan on in the tent??

  14. Dirk Ketron on May 15, 2022 at 6:54 pm

    The #1 biggest mistakes I see out of new growers is treating them like they are growing house plants (miracle grow and water). 😅🤣😂😭

  15. Sid Grover on May 15, 2022 at 6:54 pm

    Lots of good info just slow down a little so a person can take notes 👍🤠🤪

  16. We6d on May 15, 2022 at 6:55 pm

    I learned I grow shitty weed and can’t afford to do it the right way. Thanks for the tips

  17. MidnightSamuraiSake on May 15, 2022 at 6:56 pm

    Make sure to give them all kisses so they know you love them 😘

  18. LtBlazer556 on May 15, 2022 at 6:56 pm

    Nobody ever said don’t use miracle grow indoor potting soil. PS don’t use miracle grow indoor potting soil. The nitrogen levels are way too damn high.

  19. roy on May 15, 2022 at 7:02 pm

    Cecelia from Weeds?

  20. Kanard Lewis on May 15, 2022 at 7:03 pm

    Are heating mats necessary in grow tents?

  21. yust1more on May 15, 2022 at 7:07 pm

    Great content & very useful information,
    Definitely things that nearly most all new growers have to overcome. 🌷🇺🇸

  22. NEIL 75 on May 15, 2022 at 7:08 pm

    This is more for people who have grown a few times. Some wont understand this.

  23. Patrick Roepke on May 15, 2022 at 7:08 pm

    PH lockouts-you can give it air, nutrients, ventilation, and a badass Fluence grow light with carbon dioxide…… WILL NOT GROW! Period! So buy a decent PH meter and calibrate weekly. My biggest mistake ever………. Will sit there with all this top notch grow equipment being wasted, pots would sit for 7 days still wet because plants wouldn’t even take water. Got it dialed in now and it grows an inch or two daily with my light dimmer barley even turned up.

  24. THUNDER & joy on May 15, 2022 at 7:11 pm

    Over watering your plant has to be number 1…
    Less is more..

  25. Mika Vangool on May 15, 2022 at 7:12 pm

    Awsome finaly a female that tells the guide
    Female explain me a female plant make.more sence haha

  26. Charles Dziedziech on May 15, 2022 at 7:12 pm

    A common mistake to go over with new growers I would say is light height from your plants. Also, over trimming fan leaves

  27. 92 Yankee on May 15, 2022 at 7:12 pm

    Very helpful

  28. Jim N. on May 15, 2022 at 7:14 pm

    Thanks for the video. Love the charts! Any tips on record keeping?

  29. Chris B on May 15, 2022 at 7:14 pm

    I don’t believe she actually smokes weed, lol. No way

  30. User619 TLSDCA on May 15, 2022 at 7:15 pm

    Trimming off WATER leaves too early and too flush of cut to stock. It do forces Plant to go idle a bit and start pre flower stage, but really, they cutting off the 3rd stage of Kola growth of PhotoPlants. Them Kolas can only get thick and wide with them 3rd set of stems.When cutting flush to stock stem, some cut off those sites to grow and wont grow..

  31. Stang Cobra on May 15, 2022 at 7:16 pm

    watering is the TOP issue, it’s very difficult and just requires trial and error. It’s always Good to have MORE perlite than less. Soil gauges give an idea of h20 moisture at the root. Also peeps tend to put their lights to close to the canopy.

  32. bobby Fisher on May 15, 2022 at 7:16 pm

    Wrong lights

  33. TheRandomRobert on May 15, 2022 at 7:17 pm

    I use a clear plastic bin for mine you can see how moist it is like the top of my bin is dry right now but the middle is still moist I’ve done outdoors but for my first indoor they’re doing great I don’t have a tent just a light fan and plastic bin with a mix of black cow and miracle grow potting mix going great in my attic since in my state the humidity is like 50 or more pretty much all year around

  34. Alan Pinho on May 15, 2022 at 7:21 pm

    How about growing outside? Thanks

  35. Flacko Da Baptist on May 15, 2022 at 7:22 pm

    dog barks @ 3:20

  36. DOCUDRAMA on May 15, 2022 at 7:23 pm

    To much false information. First, flushing isn’t pouring water until 50% runoff, that’s just another watering. You have to run 10x the amount medium. Which usually requires 20-50 Gallons of Water.

  37. Lonso Baldwin on May 15, 2022 at 7:24 pm

    It’s 72 Bad to grow cannabis plant and door in a tent ?

  38. Bryan.R on May 15, 2022 at 7:24 pm

    How do you exchange air when lights are out and every things turned off or do you do nothing?

  39. funny bunny on May 15, 2022 at 7:28 pm

    number 1 they learn it watching you tube

  40. Nola Black on May 15, 2022 at 7:28 pm

    Thanks Amy. ✌🏿

  41. Roman Nero on May 15, 2022 at 7:31 pm

    Im making 3 out of 4 mistakes smh 😣

  42. Daniel WestCoast on May 15, 2022 at 7:32 pm

    How much is this whole set up? And for how many plants??

  43. Jonathan Kravitz on May 15, 2022 at 7:32 pm

    My seeds have a tap root- I planted them in soil. Do I turn the led lights on or leave in darkness until they sprout? I am unclear- first timer?

    Thank you


  44. Randy Wabegijig on May 15, 2022 at 7:33 pm

    Question for exaust fan when I have it on can I keep my vents closed or do I have to keep one vent open

  45. Cannabis farmer 420 on May 15, 2022 at 7:34 pm

    I just got that exact ventilation kit 🔥

  46. Tim Page on May 15, 2022 at 7:37 pm


    But so much about over wateijg or under Watering .

    So many people just dump water in and the water just drains out the sides of the pot.

    Its best to water a lil bit let it get absorbed then water a bit more.
    Water in bits so the media gets throughout saturation.

  47. NkxZomBieTriX on May 15, 2022 at 7:37 pm

    PH should have been mentioned. I see growers check their PH then mix nutrients and not check again before feeding. PH is such a major factor in growing because even if you’re feeding them the right amount if you have the wrong PH they can’t intake them

  48. Tucker on May 15, 2022 at 7:38 pm

    Overwatering and way too much humidity at the seedling stage

  49. Snob on May 15, 2022 at 7:38 pm

    Make sure the fan is oscillating. I learned this the hard way.

  50. Pamela Sellner on May 15, 2022 at 7:39 pm

    Took three grows to eradicate powdery mildew.
    Mistake: introducing a clone from another grower. It was infected with mildew. It went to each grow space within a week.. i tried all inhome remedies.. it was an incredible lesson.
    Never I mean NEVER accept anything or anyone into grow space. You must sanitize and roll clothes. But, when in doubt DON’T!!
    Then i was introduced to Trifecta (cost is worth every $$) it started in middle of grow #5, now on #10. Last three NO SEEDS (Amen). I use Trifecta every watering. I dilute in 1/2 of what it calls for to eradicate.. NEVER LOST A GROW… all was good, just reduce in size.. Quality was good also.. dont give up!!
