Dude I love u Bruce thank you from the bottom of my heart for the education that you provide the community with! you are seriously the best! Keep bringing these amazingly important videos
Like always Dr. Bruce Rugbee hits it out of the park this video is💯% knowledgeable thanks for all the studys you do that helps are community keep the awesome video coming
And to think, my need to Blaze has been the drive for me to study my electrical and computer engineering so hard I might actually get the degree. You and your team's work are absolute inspiration.
Bruce first and foremost thank you so much for the invaluable information in lighting and plant biology you provide to us for free. I happen to be watching this the night of a full moon and was curious about the claim about not being able to read a book by moonlight. Took a small print paperback outside with very little additional light pollution and with relatively little strain could read it by moonlight. I'm sure the point as a rule of thumb stands but wanted to share, thanks again.
This is great info Dr Bugbee! I have a hypothesis about green photons. As you've noted, they penetrate deeper into plant tissues. I propose that those photons bounce around hitting various organelles within the cells until their energy state degrades. In other words, they eventually turn red and then get scooped up for photosynthesis, etc.. It's similar to the way blue photons pass through a phosphor coating and turn green.
Hello dr. Bugbee you are doing a really great job in your studies. I'm from Germany and I really like to watch your nice videos with your absolutely great insights. It would be interesting to know how long light pollution has to exist to cause problems. :) keep it up and stay healthy. Greetings from Germany
Very interesting Dr. B! I was going to ask if hermaphroditism begins as well at 10+ nanomoles but then you answered that question later on. I will say in respect to your statement on that matter, there are some home breeders that have been known to turn a light on (for example) for 10 minutes in the middle of each dark period for a week, to produce pollen sacks in their females. I'd think you would be breeding hermaphrodites mainly but that's another topic. I am curious if those doing such a thing actually had some other stress factor involved maybe? I found it fascinating how the temperature regulates the level of effect caused by light pollution as well. Love the work you do, and the fact you share the information with us! I am looking forward to the next one!
I was really wondering about this. I even thought about if a full moon would disturb them. I also really liked how the analogy of reading a book was used for those without light meters. That's really handy knowledge there.
Same rhetoric about the same story, light is light and dark is dark...with indoor grows you are the one that plays God, you control every aspect of the child you raise...it's been taught that a break from light cycle during flower stage can trigger the hermaphrodite in a feminized plant, I for one have never experienced this after well over 300 grows! Light cycle duration is the key. .once your plants are tuned in you can pretty much dictate the life course of said plant
I appreciate the wealth of knowledge you share..its definitely special, invaluble if i must say so myself. You have helped me GROW (litterally & figuretively) and you dont even know any of us. I appreciate the decency as a human being, the acknowledgement you're directing at medicinal cannabis.thank you kindly,
Thank you so much for all the information and knowledge you present to us. As you pave the way, your hard work, dedication, and knowledge is a beacon for all of us growers.
Thank you, very informative. I must say, that since my childhood I remember the full moon is so bright so I can easily read the book and see my own shadow on the ground. That should inhibit the flowering, but why it still doesn’t ?
As always, Dr Bruce Bugbee explains it based on science....real science. not bro-science. Keep up the great work Dr.!! You are my go to for cannabis growing!!!
Very enjoyable lesson. Love the scientific measurements, the great teaching style, things being described and explained in a very interesting and knowledgeable way.🙂
Dr. Bugbee, thank you my friend! I have so much respect for this man. Always respectful in the way he teaches and full of so much knowledge. Thank you, I can’t stress to you how much this lesson and overview has helped me. I’ve always wondered how much ambient light is too much light. I really connected with your analogy about the book and not being able to read it with ambient light no brighter than the light from a full moon! You rock my friend! So much gratitude, thank you!
Very informative and great info to build/ grow off of. Science has always fascinated me. Thanks for the studies and the free info your putting out for us home growers and commercial growers.
Muito obrigado por partilhar tantas informações tao valiosas para tantos de nós do fundo do coração .Você partilha conhecimento valioso para muitos de nós! Abraço de Portugal! Thank you so much for sharing so much information so valuable to so many of us from the bottom of my heart. You share valuable knowledge to many of us! Hugs from Portugal!
I need to know where the plants he was growing now came from vs the plants used in the 70s study. The plants from the 70s study could have been from outdoors and have adapted to moonlight naturally. The plants he used now could have been grown for generations indoors and their threshold for light could have gone down.
YOU SAVED MY ENTIRE CROP OF 8 PLANTS FROM RQS COMPANY. This is my first grow and I knew about the light during budding thing. What I did not put together was that my "Clone Room" (bathroom lol) and my Kitchen were pointed directly at the plants. They stopped EVERYTHING and after I watched this I went out to see how dark it was. It wasnt. I turned them off and after only 4 days they are doing GREAT! THANK YOU!!!!!!
I love how we use the Scientific Method to coax out the truths in the World... The whole framework of higher education and graduate programs enable individuals to take the deep dives that makes these answers possible. Even better is when during this research there is some accidental discovery that is found by keen observers.
If closed everything up & had a exhaust that's double (min) to triple in other words 4×4 u need 175 cfm coming in the bottom of tent on non stop when lights on & a exhaust of 350 to 450cfm u will get negetive pressure & then any flap or drain hole u open in the bottom of tent fresh air will gush in for free! It's like having fans at 75cfm for free where ever u have openings. If u get support poles u won't have to pit up with ur walls caving in & loosing quater a foot from each side of ur tent so you don't loose yield! Keeps orders in, keeps humidity stable, keeps temps stable, keeps pests away cause they feel the negetive pressure from meters away cause there so lite & stay away & much more plus fresh air coming in ur tent 24/7 & excellent for maintaining humidity at. Light. Will never rise more then 10% after lights off. If u don't have negetive pressure ull have the probs u have with temps & Humpty but more so temps, that's why it don't work for you. Give it go champ. And all the benefits I mentioned ur missing out on plus blowing odorous out of ur tent & giving access to pests & ull have to LITRILLY live with them to maintain environmental. Happy growing & nice plants but u should make more use of every square foot & inch
Fk ya big Bruce!!!! I've been educated by you over 3 years now I remember the days where cannibus results weren't specifically mentioned. Awesome to have you to educate accurately as you have. Question if I may?? Inverse square law? Positive I know the answer just curious if I'm smart as I think. Any input would be welcomed. Always wondered about moonlight or harvest moons n such. Thank you again.
My Last run finished right at a full moon outside at 2100' elevation and I lost density on my flowers. Not the first time. I just bought black out plastic. Aloha from Hawaii.
Does the "safe zone" remain constant-ish over a range of temperature with all else being equal-ish? I'm 52 and use "-ish" because I've learned most science suffers from it. From a purely observational perspective, if the cannabis plant become hermaphroditic because of a light, such as from a power strip, dehumidifier, etc., then it had one or more problems doing what it wanted to do; otherwise, it did exactly what is was going to do. Moreover, light becomes a part of the problem as the building-blocks of problems increase.
Nothing worse than wondering why you are running out of space wondering why your plants arent flowering just to find out you got a massive light leak Ive always used "if you can read a book for senior citizens (larger font) in the room its to bright" Outdoor we can only do autos because theres multiple street lights right next to the garden
Thanks for sharing and doing what you do. Fantastic. One thing I would like clearing up is @5:26 "if we assume that this is based on sunlight reflected off the moon." Here's the issue, direct sunlight records higher temperatures compared to measurements recorded in areas that are shaded, agreed? It's slightly cooler in the shade. Moonlight on the other hand produces the complete opposite. Moving the gauge from bright moonlight into a shadow region produces a temperature increase. It's warmer in the shade. Sunlights properties are turned on their head and this makes little sense does it? Any advice?
So interesting and enjoyable to listen to. Moonlight at night and the whole darkness subject. Marine Boot Camp we trained for moving through a jungle at night. Night vision or when our eyes adjust to see whatever they can in the dark. It takes awhile for eyes to adjust but if exposed to light, like a flashlight or flare, we lose our night vision immediately and to get it back takes minutes and the longer the better for seeing better in the dark or night vision. Preserving that night vision is a big deal for any of us. Once you have the night vision from being in the dark for a half hour and a light comes on, immediately close your eyes and cover them or ya lose that half hour of building up the night vision. I’ll blame it on coffee. Thanks Bruce 🤙🤙
Whenever I want to initiate darkness for my plants, I just show them the news.
I’m right there with ya friend.
LoL
Dr. Bruce Bugbee, the rock star of photobiology!
It's a dirty job, but somebody's gotta do it...
Thank you for making this available to everyone! As always, awesome presentation!
Dude I love u Bruce thank you from the bottom of my heart for the education that you provide the community with! you are seriously the best! Keep bringing these amazingly important videos
Dr Bugbee is just simply amazing at his job. It's like watching a beaver build a dam, he was born to do this.
So true! Just admire and soak it in
What a great analogy.
Wow Dr. Bruce, I actually understood most of this! Looks like 5 years of high school paid off! Thank you, and God Bless!
This is the kind of research we need more of. Keep up the great work, man!
Damn Skippy man. Blows my mind how quick thought stops and incomplete knowledge is accepted and shared smh damn fish keeps growing lmao.
Amazing! Great stuff. Looking forward to the results of short exposure to intense light and plants reception to light at low levels
Like always Dr. Bruce Rugbee hits it out of the park this video is💯% knowledgeable thanks for all the studys you do that helps are community keep the awesome video coming
And to think, my need to Blaze has been the drive for me to study my electrical and computer engineering so hard I might actually get the degree. You and your team's work are absolute inspiration.
Smart growers and scientists alike are taking notes here. Good stuff.
Thank you Dr Bugbee. Very interesting. Look forward to hearing the results of a burst of light during dark vs the continuous low low light.
Dr. B, always crediting the folks who do the grinding work. Classy AF.
Quality information, looking forward to the continued research you provide!
Congrats Paul!!! Everyone appreciates your hard work and devotion to this research!
Major protip about green lights in the grow rooms at 24:25

I wondered the same thing. The test is very subjective. Young sensitive eyes vs old dull eyes.
Absolutely fascinating subject matter, Dr Bugbee - thank you.
Amongst the brightest minds in the growing world. Thank you doctor.
Not too bright, it would interfere in the plants
Bruce Bugbee IS BACK, God Thanks! Much Respect and Keep it on! @apogee Instruments Inc.

Thanks for all the work you do!
thanks for the work you guys are doing for the comunity. this is great and greatly appreciated.
I've been hoping Dr. B would address this. Thank you
Thank you for presenting this amazing research! I also love your name.. VIVA BRUCE BUGBEE !
Thanks so much for this. I am going to do my first outdoor grow this year, and have been wondering a lot about this.
I feel like I just watched my dad try to read a book in the dark for half an hr. 🤣🤣🤣 Thanks for all you do Dr. Bugbee!
Thankyou Dr Bruce this has explained light pollution and the fact green light isn't safe to use to view flowering, valuable information.

beste MAnn!!!!! im so thankfull for all he posts. 🙏
Great video! I was always thinking about it.
I have one idea to try, what about UV light from bug zappers? Does it impact the plants?
More brilliance from the master. Thank you Dr. Bugbee and colleagues/staff
This is so interesting. I'm completely hooked
I wanna see a Good Study on IR Night Vision Security Camera Light's... Safe or No...?
No
I feel like im 19 again, back in college, hungry for knowledge, amazed by the wisdom of professors
Thank you for the work, Bruce 🙏

Light cycle duration is the key. .once your plants are tuned in you can pretty much dictate the life course of said plant
I’m calling this the “loose Bruce” look. Love it. Maybe tie-dye next video?
Been waiting quite a long time for this ever since the lab tour.
Good science takes a while.
awesome segment
Bruce is my favorite teacher. I wish I could've studied under him while getting my undergrad.
I appreciate the wealth of knowledge you share..its definitely special, invaluble if i must say so myself. You have helped me GROW (litterally & figuretively) and you dont even know any of us. I appreciate the decency as a human being, the acknowledgement you're directing at medicinal cannabis.thank you kindly,
Man thank you for you in depth research been watching you since the lab coat and long hair lol. You're the goat keep it up🐐👏🏽
Thanks again for your dedication to light science. Great lecture.
Thank you so much for all the information and knowledge you present to us. As you pave the way, your hard work, dedication, and knowledge is a beacon for all of us growers.
Thankyou Bruce! Wish you taught at University of Hawaii at Manoa.
Happy 4th of July thank you from London for all your amazing work love all your videos
Wonderful man, i forget to eat when watching his science.
Thank you, very informative.
I must say, that since my childhood I remember the full moon is so bright so I can easily read the book and see my own shadow on the ground. That should inhibit the flowering, but why it still doesn’t ?
This whole video was about how the full moon is not at all enough to disrupt flowering...
Awesome channel.
Is there a DOI or some sort of reference for the study results being highlighted here: 12:10 ?
This is good information. I’ve often wondered about this.
Thanks again
As always, Dr Bruce Bugbee explains it based on science....real science. not bro-science. Keep up the great work Dr.!! You are my go to for cannabis growing!!!
You're the best Dr. BB! I always look forward to every video. Thank you!
Great video!
Thank you for this
Daaang! Green light is NOT safe for night use. That was a big mix drop right there.
Thank you so much for all the work you do and that you take time to explain it in the most basic ways that any person can get a handle on it.
Info at 16:00 is aweseome!
😂
Thank you. I'm not sure how I stumbled upon this gem, but it was very insightful and helpful
Great video thank you !!
Very enjoyable lesson. Love the scientific measurements, the great teaching style, things being described and explained in a very interesting and knowledgeable way.🙂
Luv this man and all the free knowledge
Once again, thank you for your contributions

Great information as always. Thank you Bruce
Thank you Dr. Bugbee! Very educational as always
Any studies on the effects of light pollution on HLPV? Could be a trigger?
Very interesting and informative presentation, thank you!
You are the man Bruce!!! Your research and info is greatly appreciated!
YOU SAVED MY ENTIRE CROP OF 8 PLANTS FROM RQS COMPANY. This is my first grow and I knew about the light during budding thing.

great rule of thumb
Awsome presentation dr., Without a doubt the most Credible source of information in regard to light and plant physiology, bravo sir
Wow, this guy is very cool and very intelligent. All can learn from him,and thanks for helping me with my personal medical plants 🪴
What do you think about IR light? - like Near IR 940nm such as a security camera? Will the IR Light affect as light pollution?
They don't mind Constant low level street lights @ 150ft away. Or car lights for just a second at a time, not alot of cars. 5-6 whole night.
I wonder what dr Bruce thinks about the lantern method or the 12/1 schedule
I love how we use the Scientific Method to coax out the truths in the World... The whole framework of higher education and graduate programs enable individuals to take the deep dives that makes these answers possible. Even better is when during this research there is some accidental discovery that is found by keen observers.
Dr Bruce I bet you have 103 % attendance in your lectures.
Another great lesson, can't wait for the next one professor 💪😁👍

Thanks for give us such a simple rule of thumb!
Very very interesting ❤
Just what I have been researching for years. Finally found it. Thank God. One ☝️ of my 6 flowering plants 🌱 Hermaphrodite
I take no chances , my lung room containing my tent is pitch black. All electrical extensions or adapters with lights are taped up 😅
My balcony is right next to a bazillion Watt streetlight. Wish my puoto lady luck :)
Fk ya big Bruce!!!! I've been educated by you over 3 years now I remember the days where cannibus results weren't specifically mentioned. Awesome to have you to educate accurately as you have.
Question if I may??
Inverse square law?
Positive I know the answer just curious if I'm smart as I think. Any input would be welcomed.

I wonder if light sensitivity can be bred out of cannibis like it's been from soybeans?
