1. Great to hear that 1.4 is ideal in flower bc that’s exactly what I have in my 2×4 at the moment super happy hearing that

2. Sorry but I disagree, you don't need a "good tent" infact in my 20 yrs indoor hobbying I find tents actually bring problems , problems I don't get when i just drop black&white plastic around them , nothing at all special 🌱 & i get Fantastic results & zero issues with bud rot / humidity 🌱 zero controllers etc etc , a decent light, a oscillating tower fan .. That's my equipment 🌱👌👍👍 Then yes during mid-late flower I'll stick a dehumidifier somewhere near them set to 50% & keep temps low towards the end helps preserve the terps & that can = far less smells 🌱👃

3. Then you have to veg for like 3 months thats a waste may as well have more plants quicker turn around

4. Im from Germany, enjoying your youtube for years. Thanks alot. Over here we just legalised…and now im all into cultivating. I just wonder where do you exactly measure all your Data. VPD temperature humidity. Do you have all controlling equipment outside the tent? Im curious…

5. Good show thank you

6. ♥️💚♥️💚🌿🌱☘️🤘✌🤙🤞👌🙌👍

7. Not in Santa Barbara! It gets humid AF here! Its chingerd me once in the past!

8. What are temps when running co2? You stating 82-82° and 65%RH.

   Are those temps still valid for a non co2 grow?

9. Love

10. According to massmedical strains humidity doesn't matter the plants will become accustomed to it lol

11. Where you at kushy I got 12 pedigrees going from dark horse gentics in ohio garden

12. Loved the conversation, your passion for this beautiful plant definitely sparks the gardener in us all❤

13. This the same guy who’s trying to sell you veganic bud 🤣

14. I grow multiple strains usually 4 to 6 of a particular strain and 4 to 6 of another strain. They grow in a double 5×5 tents next to eachother and opened up. But they're in a sealed ac d and conditioned room. I am the master of their atmosphere and get excellent flowers. In a stagger of 3 to 4 weeks per strain. Perpetual.
    Hope that wasnt confusing, it almost confused me.

15. Can you warn people about what people call "bat shit crazy"?

    Maybe talk about holistic remedies that can kill the parasite?

16. Kyle you’re a legend

17. My b the duct holes 100% perfect😅

18. Droppin knowledge ! Excellent upload

19. For me,, in a basement lung room, I run a lot of dehumidifier. And I can’t keep up that low humidity, at night lights off, it just jumps no matter what I do. 60 degree nights, 70 degree days, week 7 of 9 flowering looks good even with night time spiking humidity to mid -to high 50’s. But it worries me, lots of air movement will hopefully be enough. Ps my lung room runs at 30-45 at night but the tent is always high no matter how much air i blast thru? Frustrating!

20. A lot of great info here thank you for putting this out.

21. Doesn't organic medium need to be moist at all times, so microbes don't die out?

22. 🎉🎉🎉🎉

23. Your putting videos on here but the site is down. What’s up with that.

24. GWAH from Philadelphia Pa!!! Since I've been growing hydroponic I haven't had any need for IPM knock on wood, am I just lucky? And is High Times magazine still in publication and print? I would appreciate any feedback you can give me. Thanks

25. Pure gold, thank you so much!

29. Great video Kyle! Thank you for sharing your growing experience and understanding! Keep dropping that Growing Knowledge!

30. I run 1.8 and 1.9 VPD the whole grow with no issues, just be willing to check on them throughout the day but with them transpiring constantly, they grow monstrously huge for autos.

31. I put blankets on my tents when needed

32. I use 150watts on 40% lol I don’t know how people get away using that much light

33. This video has been soo helpful! Thank you. Convinced me to connect my portable HVAC to my AC Infinity Controller!

34. Is this Kyle "Kushman"'s grandfather?

36. Hey man maybe u can help I run x2 600w hid to flower there hung over 8 plants in 3gal fabric pots and I’m on bio bizz all mix soil with the full range of bio bizz organic nutes in use, I grow In a spare room it’s just wk 3 o flower niw and everything is flying along 50% rh and 26oC it sits at naturaly. So great for vegging but as I flower now I’m away to purchase a mobile a/c unit plus dehumidifier do u think I need this ?I think so but what do you think looking for answers before I spend the £££ ?please help👍

37. 27:45 should I ever increase the food (ppm) even if the plant doesn't have any deficencys

38. Duuude,u rok it KK!😂U should b a comedian bro!

39. my only problem is i dont wait long enough before i harvest when i feel the buds and they are the feeling of squishy spongy i harvest but i think i should wait 2 weeks or 3 then they would bulk up more also but what do you think ?

40. Hey Kyle this type of content is very good . Podcasts can be heavy for listening

41. You suck. Strawberry cough sucks also.

42. Very, Very, important!!!!!

43. NO NEEm. But great ep

44. I actualy have a vpd os 1.3/1.1 in ma grow tente but the leaf of the plant said to me that the environment is too humid .. why ? The rh is about 60% and i am in week 4 of vegg !??

45. I bought a dehumidifier because it's humid only during the summer months where I'm at but the dehumidifier creates to much heat and cancels out my air conditioner . What's a good dehumidifier that doesn't put out heat into the grow space?

46. Once you understand VPD, everything gets MUCH easier if more expensive because of humidifiers and dehumidifiers along with air conditioners. Nah, It’s not that much for a typical indoor home grow. DEFINITELY worth shelling out a few hundred for decent environmental control.

47. Some days ago I was able to put "my" plant outside. First plant since 24 years waiting, first outdoor ever. I was soooo happy when I discovered a random bug on it. Because the bug was chin-checked by an ant. No idea why everybug and their mom is on my second floor balcony in the city…but my living soil is indeed alive. "My" plant just wants to be free, without PH, EC or VPD 🙂

48. Respect brother love from the UK 🤙🏻

49. BIGTURP is in your tent

50. ✌️😎🔥🔥🔥
