Thank you very much for your enjoyable informative presentation.
Using 2x 1000w LED full spectrum and 2x 1000w red and blue, I thought it was a good thing to turn off the blue for the flowering stage.. and now I m thinking of let em all on.. Is this right? Anyone ? Do I get this right,,? All on , more light = more yeild possibility.. color don t matters? Anyone? Thks
So should I run a 24 hr veg? Or stick to 16-18 hr? If your data is correct, then the only downfall to running 24 hr veg is the increased responsibility of making sure the other 8 parameters are kept optimal.
Sooooo….what about light pollution and effecting growth? How much light pollution will cause hermaphroditic tendencies in an indoor home garden? In comparison to the full light moon at night outdoors?
Fuck! I would listen to this video with 20k likes on it, but right off the fking bat this guy acts like there is a difference in hemp and cannabis and there isnt. cheebah is to the 50-60s, and is what hemp was to the greeks both are cannabis aka marihuana. got to love some people that mis educate others and dont like watching or sharing their shit because of it. signed arkansas advocate
Wind isn't actually needed at all, just saying, sure it builds strength but you can have zero wind, zero movement of air but natural and from breathing on it and it'll still turn out fine
Hello Dr. Bruce bugbee, i have a idea, What if you made a LED light that put's out the same amount of Lux as the Full Moon and ran it at light's off would the plants get used to it and be less effected by light leaks then?
Quick question, have you studied the photosynthesis rate when using a grow room painted with some of the new darkest black like Vanta black or Musou black? Very curious as to the results if you make 99 % or more or any residual light get absorbed into something other than the plant.????.
He had info of adding a little UV spectrum to plant to boost defense mechanism to produce more THC and tricombs. I got a UV LED DEVICE and zap a couple of Kolas ( had 45 uv diodes at 6watts ea so it was just 30 seconds 2 x a day) Well, those 2 Kolas tricombs thicker then top bigger ones at 3rd week into flower stage..

Man why don't teach this in school ? i've stayed whole video stuck in my char learning about lights for cannabis . useful !
Within the first 5 minutes this man is comparing cannabis to race cars. I came to the right place.
thx learned a lot
What ever happened to just 1

For autoflowers question: should i stay with 45 moles per day without aded co2? thats mean around 700ppfd over 18 hours light shedule?¿
Why do I feel like I'm listening to Jordan Peterson?
concise and effective content!!
When he says light quality don't have a significant affect on the ration of canabanoid production. Do this include UVA UVB?

33:48 How about UV-B and THC production?
cannabis sure does grow like a racecar
i planted a few this year and my family is astonished by how fast cannabis grow
Ok light sensitivity but what about the moon

What are optimal night time temperatures, humidity, CO²?
