How Dark is Dark Enough? Darkness level requirements for plants with Dr. Bruce Bugbee

[@TheUnholyPosole]

Whenever I want to initiate darkness for my plants, I just show them the news.

[@StephanMackie-dy2xm]

I’m right there with ya friend.

[@Jesuscristorey-777]

LoL

[@sethrogers1327]

Sad but true

[@racebiketuner]

Dr. Bruce Bugbee, the rock star of photobiology!

[@beauregardb6108]

It's a dirty job, but somebody's gotta do it...

[@marktaft]

Amongst the brightest minds in the growing world. Thank you doctor.

[@EduardoMusasa]

Not too bright, it would interfere in the plants

[@danrobinet1785]

Thank you for making this available to everyone! As always, awesome presentation!

[@MrBlunt32]

Info at 16:00 is aweseome!

[@hamsack981]

😂

[@Albopepper]

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.

[@nomecisto7200]

Dr Bugbee is just simply amazing at his job. It's like watching a beaver build a dam, he was born to do this.

[@user-ne9sd4ow1o]

So true! Just admire and soak it in

[@luizz_k]

What a great analogy.

[@bulbaboi420]

This is the kind of research we need more of. Keep up the great work, man!

[@christopherparis6841]

Damn Skippy man. Blows my mind how quick thought stops and incomplete knowledge is accepted and shared smh damn fish keeps growing lmao.

[@pops8975]

Congrats Paul!!! Everyone appreciates your hard work and devotion to this research!

[@pawelchmielniak3275]

Amazing, thank you! It's rare to find genuine science talks on youtube.

[@BroncoFan6548]

More brilliance from the master. Thank you Dr. Bugbee and colleagues/staff

[@camthecannaman]

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

[@zacharytaylor8523]

Been waiting quite a long time for this ever since the lab tour. Good science takes a while.

[@youvegotmysong]

Bruce is my favorite teacher. I wish I could've studied under him while getting my undergrad.

[@camarodude9615]

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

[@kevinwilson2082]

Wow Dr. Bruce, I actually understood most of this! Looks like 5 years of high school paid off! Thank you, and God Bless!

[@jasonknight5045]

thanks for the work you guys are doing for the comunity. this is great and greatly appreciated.

[@jblazer2492]

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.

[@coreyn]

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!

[@chris432t6]

You're the best Dr. BB! I always look forward to every video. Thank you!

[@bradfordblevins8310]

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.

[@iamachine]

I wondered the same thing. The test is very subjective. Young sensitive eyes vs old dull eyes.

[@TriStateTrichomes]

Amazing! Great stuff. Looking forward to the results of short exposure to intense light and plants reception to light at low levels

[@rickymackie2340]

Smart growers and scientists alike are taking notes here. Good stuff.

[@kroscuro]

Thanks so much for this. I am going to do my first outdoor grow this year, and have been wondering a lot about this.

[@MonstermashLabs]

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.

[@Jesuscristorey-777]

Just what I have been researching for years. Finally found it. Thank God. One ☝️ of my 6 flowering plants 🌱 Hermaphrodite

[@2bNot]

Very enjoyable lesson. Love the scientific measurements, the great teaching style, things being described and explained in a very interesting and knowledgeable way.🙂

[@dertythegrower]

Major protip about green lights in the grow rooms at 24:25 🧠

[@xx7101]

Dr. B, always crediting the folks who do the grinding work. Classy AF.

[@CharlesLaBuhn]

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!!!!!!

[@MrJD0116]

Thank you. I'm not sure how I stumbled upon this gem, but it was very insightful and helpful

[@Wise-Monkey]

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

[@clwnpRon]

Quality information, looking forward to the continued research you provide!

[@Pure_Science_and_Technology]

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.

[@dertythegrower]

Thank you for the work, Bruce 🙏

[@recharge5620]

This is good information. I’ve often wondered about this.

[@RowsOfGreen]

Thanks again for your dedication to light science. Great lecture.

[@kris.herring]

Absolutely fascinating subject matter, Dr Bugbee - thank you.

[@BK-pc6ov]

Awesome follow up on one of your videos from 4-5 years ago ! This is awesome. Thank you 👍

[@beauregardb6108]

I've been hoping Dr. B would address this. Thank you

[@bradburyconstructionllcjos9751]

Great information as always. Thank you Bruce

[@angelsantiago3390]

Thank you Dr. Bugbee! Very educational as always

[@chapultepec]

Thanks for give us such a simple rule of thumb!

[@nevinjames3674]

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.

[@iamachine]

Interesting thought.

[@Albopepper]

Is there a DOI or some sort of reference for the study results being highlighted here: 12:10 ?

[@lowprogrow1603]

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.

[@user-ne9sd4ow1o]

You are the man Bruce!!! Your research and info is greatly appreciated!

[@gnawbabygnaw]

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 🤙🤙

[@andriykorobov]

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.

[@annakoton773]

Congratulations and thank you for a great presentation. There are still people who doubt the problem posed by light pollution for the environment, including plants. I myself often mention this problem in lectures.

[@NheksPT]

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!

[@huejassle3019]

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,

[@tigerwoods373]

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.

[@izzem]

Once again, thank you for your contributions

[@illumencouk]

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?

[@MasAlaMode]

Thank you for presenting this amazing research! I also love your name.. VIVA BRUCE BUGBEE !

[@DegustoDelSol]

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?

[@Jesuscristorey-777]

Very very interesting ❤

[@Axiomatic75]

Very interesting and informative presentation, thank you!

[@AtollSurfer]

Love the presentations, my experience is a saber of light from a pin hole can cause hemihedrite issues in a Dark Room / Grow Room . Leaving the door open all nigh to background lights seems ok. Growing next to house, that light (s) from the house did not make an issue.

[@tableshaper4076]

Thanks for all the work you do!

I feel like im 19 again, back in college, hungry for knowledge, amazed by the wisdom of professors

[@MastA420]

Ive been contemplating trying my hand at light dep and this just gave me some very valuable information. Thank you good sir

[@bolster101]

Thankyou Dr Bruce this has explained light pollution and the fact green light isn't safe to use to view flowering, valuable information.

[@ZoltrixGrower]

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 wonder what dr Bruce thinks about the lantern method or the 12/1 schedule

Great work! Much appreciated 👍

[@Spartanz255]

Dr. Bugbee, do the plastic planting containers leach plastic into the plants? Thanks

[@Weareallequal273]

I was hoping this would help me answer the question: Is it ok to open the air vents on my grow tent during the plants dark period, while having a 24 inch computer monitor on half brightness in the same room.

Thankyou Bruce! Wish you taught at University of Hawaii at Manoa.

beste MAnn!!!!! im so thankfull for all he posts. 🙏

[@bondedomao]

I wonder what will be the results of brief flashs os lights at dark times. I do the dark time at day and sometimes it's when I tend to it, I can't just easily darken it all my room when I open the grown.

[@konstantina8267]

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 ?

[@thomasoravec528]

This whole video was about how the full moon is not at all enough to disrupt flowering...

[@historyandhorseplaying7374]

Have studies like this been done on tobacco plants?

[@toastiesburned9929]

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!

[@CARLHPMA]

Would love some research on autoflowers I feel we know even less about them because Bruce has opened our eyes on regular medical cannabis

[@nekromania]

AutoFlower is Bullshit..
