Thanks. It was a real pleasure to do. I cut it down from over an hour but I think it's too long for most. I'm going to extract some of the gems of info to shorter videos for those with shorter concentration spans than us 😉
@@MIGROLIGHT It would be interesting for someone to help with the subtitles in Spanish, there is a large community in this language that would be grateful to have all this wonderful information translated. Greetings and many thanks for this great contribution.
@@MIGROLIGHT definitely do it!!! thou myself & i had to stop to take notes and rewind alot also. im a noob trying to learn about lighting. etc. i feel like "Wow" 'you ask for it ' this gives me trust in Migro...see u later
Soo interesting to hear experts coming together to try and dispel some of the common myths which surround our industry. Knowledge is power, thanks again for open and honest content.
Two of my FAVORITE CHANNELS to watch. Check out BUILDASOIL. All 3 of these channels are very good too. NO NASTY stomach churning musak, no nontalented people trying to entertain you, and NO wasted time with a COOL DUDE letting you watch him hit a bong every video! .
We need more and more of people like Dr. Bugbee. We need actual science to help the lighting industry grow...which will benefit us...the consumer. It's all been so hot and miss up until recently. We purchase light and have to trust that the marketing claims of the product are sincere. Without actual science behind it... we have just been buying what appeals to us ...or...what we thought was the best bargain....then crossing our fingers and hoping it was gonna work! People like Dr Bugbee and Shane are much appreciated.
Very interesting information, Migro is for sure a honest trustworthy company. I trust the quality of there lights along with there honest approach makes makes me want to buy one of there lights.
One thing about this interview it was about the best I have ever seen done with Dr. Bruce. It's all about the questions you asked. No one as of yet has had the intelligence to find out as much valuable information as you did. The show is amazing thanks to the intelligence of the man doing the interview! Fifty potential shows in all this info.
Dr Bruce Bugbee YOU HAVE TAUGHT ME A LOT. THANK YOU for showing us the NEW things that are on the fore front of technology... "FAR" "RED" Intriguing.......
Extremely interesting and captivating! Thank you so much for sharing this knowledge! Do you reckon there might be a part 2? I'd love to hear more about far red, and how to implement it efficiently into a grow (what time of the day/night cycle it should be used, what stages of plant development it is more beneficial for, what impact it has on plants on a metabolic level...), along with stuff such as Emerson effect, or possible benefits of high CRI lights, versus the obvious disadvantage of a lower PPF/W. Please let me know, I'd love to watch another video as instructive as this one!
This was very interesting to watch and I learned a lot from it . I'm coming to this subject from a planted fish tank perspective with all this which has slightly different parameters that affect plant growth such as the depth of water and how tannins can affect the overall light distribution such as when you have a biotope species specific tank like from the Amazon region where the water can be darker because of the tannins from the leaf decay . Also if you have a saltwater tabk with live corals the blue end of the spectrum is vital to their health and reproduction which is why a lot of people have been using metal halide lights for many years now . Also ultraviolet light is important to reduce algae blooms as well as reducing pathogens in the water which is why many newer fish tank filters have UV light sterilization to assist in the overall health of the tank . This study of sunlight replication is also extremely important to understand when it comes to any future off world colonization efforts such as any colony on Mars where UV radiation is much higher and dangerous to any life forms . Using artificial lighting will be a must have for the colonists . Although they could use the natural sunlight in greenhouses like we always see in the movies the fact is that they'll have to have special coatings to reduce the amount of UV light plus suplimental heating and if there's a massive dust storm ,how would they be able to make use of the sun if the sky is choked with dust and sand everywhere around the entire planet for months at a time ? If human beings intend to colonize Mars we'll have to get all this worked out long before setting up any operations on this planet and using solar power alone for above ground greenhouses won't cut it . They're going to have to use old lava tunnels to shelter from the radiation and use artificial lighting only but I digress . Anyways great stuff and very interesting .👍
I've always gone with what my plants tell me, I use to used 2 x de hps in a 2 x 1 m2 covering 8 plants now I run 1 hps running at 500w in the middle covering 4 plants and four veros 2 at each end 1 cob covering a plant, I save 300w in heat which Improves overall quality of yield, basically I find hps,led cob,hps,led cob an even mix with hps overlapping the led cobs work the best all day long ,happy growing ✌
I just wanted to make an observation. It takes all kinds! Light is good and light is life. As the founder of MIGRO you have observed particular benefits of LED lights. Therefore you have specialized according to your nature, blazing a trail into a particular and important specialized artificial lighting method. I find the same tendancy in myself. I do have epiphanies. But most of the time I find things that fascinate me and want to specialize in maximizing very localized knowledge. This approach is critical for understanding and maximazation of the intricacies of every field of study. I have learned from you. Be encouraged.
This was a dope talk. Thank you both. This was very helpful to me as I research on lighting technology to help me grow bonsai indoors. For the most part, the goals for growing bonsai are very different from growing weed, but there are some crossovers and this information was very useful.
With Rec Cannabis being legal in Canada in a little over a month there are already several studies being set up in jointly funded programs by Universities, Federal Government and BioTech Companies. So the ban on Cannabis research is about done finally. The studies I was informed of are more involved in compounds produced by strain but growth and chemical development as influenced by light would not be far away. Excellent insight on lighting from the masters. Thank you very much.
5 years ago I was getting slightly bigger plants . The only difference IS that I retired two old led panels from Holland with far red diodes. I am going to use them again.
Good show I tell all my friends to watch you. I help out medical patience set up they're lighting properly. I have learned so much from you I really appreciate it God bless you keep up the good work
Very informative. So the question now is which LED light is the best LED grow that utilizes all spectrum of light for best quality outcome and most yield? The mighty question.
I'd love to see new research on this since LED tech has exploded in the last 5 years since this study was done. Curious if LED has become more superior or if they haven't seen any improvement since the study.
Thanks again guys. You both do so much to assist the community. This is more than interesting. How much uv light over seedlings to control mould spores. The little evil Downy mildew spores are killing my seedlings. There are spores on the collydons when they pop through. Help please!!
Correct me if I'm wrong but if I hear ya right. More green light in say a start room would be better since most of their energy absorption will be indirect and through photosynthetic means?
Great questions and answers. Very thought provoking. PPFD is superior to anecdotal yield data? The McCree paper was an intellectual leap, as mentioned using crude instruments by today's standards, yet those results are still so significant some 40 years later.
Great show! I'm going back to my old school metal halide for veg and HPS conversion bulb for flower! I grow such a small amount for myself that the cost of going with the latest and most efficient light trends don't outweigh the ultimate benefits of both the spectrum and the added (free) heat that using HID bulbs gives. With LEDS, I have to run a heater....So if I run efficient/cool LEDS and have to add back in the "inefficient" heat that an HID bulb gives off, by using a heater, then the system becomes basically equally inefficient in either instance....right? Kind of a "Robbing Peter to pay Paul" kind of trade off, wouldn't you agree? An HID bulb seems to take on a dual role of both light AND heat all-in-one! The old school growers got it right 50 years ago and STILL have it right to this day! MH to keep those old landrace sativas from stretching too much and then follow that with the sick, orange colored HPS for to make bigger towers on the compact plant structure. Thanks for a great show and thanks again to Dr. Bugbee.
Ive wasted lots of time and money on led lights, still using hps and its still the best for me imo... I will be using D ended for a few more years as im not convinced in this book of evolution your creating
A great interview with Dr BB, always love watching your vids. I normally learn something from you but it must be said that this has flipped the script on things (I THOUGHT) I knew, thanks Shane
One thing neither of you touched on is ,what’s the best light recipe from veg to flower obviously the dli would have to increase and may be even tapper towards the end of the plants life so it would be interesting to know Bruce’s recommendation on the plants 🌱 dli from seem to harvest???
From NB Canada. Was just about to procure some LED's for cannabis. I'm unable to transfer the info in this video over to my purchasing decisions. Overwhelming. ... I want to do it as correct as possible the first time. Can you give the 'Readers Digest' version of this information? ie what should growers change or add to lighting choices. Thanks.
Hi,In short if you are buying LEDs you should go for white LEDs in the colour temperature range of 3K to 4K. There is a balanced Blue, Green and Red mix in these light spectrums all of which the plants use and need for healthy development. What Bruce is saying is plants need and use all types of light in the PAR spectrum and a broad sepctrum LED will do that.
With uva improving rooting, and ir improving the absorption of uv, via aiding increased photosynthesis.. have there been any studies on optimal rooting spectrum? Or simply put, does rooting occur more in red, blue, green, rb(blue dominate), rb(red dominate), rgb(r dom, b dom)
Professor Bugbee, Will you be accepting Adam Dunn's invitation to come see on his 5 May episode to compare and contrast conventional photobiology with what is being called "Quantum" or "Teslan" Photobiology in discussion with the Farmer in the Sky.
Interesting video.Surly tho The Green light penetrates to the lower leaves better simply because the wave length is smaller and would pass easier then red light.
Wow I learned more from that than months of frigging about doing my own research. MIght have known I'd get some the answers to the questions I had right here @ Migro. Thank you to you both.
a question... was the green light penetrating the canopy to aid lower growth a controlled test introducing only pure green in conjunction to blue/red side by side to those with only blue/red or were there other contaminants in the cyan, yellow, orange range?
Bugbee is a conventional photobiologist. Unlike conventional photobiology, Teslan photobiology looks at how Wave Mechanics affect the availability of energy. You can not understand the efficacy of a properly-tuned radio by studying improperly tuned radios. The entire range of Photo-biologically Active Radiation 280-780nm MUST be there in the correct relative amplitudes to actually understand a given cultivar's photonutritional needs.
Thank you for the video ! I learned so much with you two. You inspired me ! I mailed Apogee employees and exchanged couple of mails with them about ppfd conversion factor which determine your ppfd by multiplying the lux with the factor because i dont have money for that par instrument. I was amazed my conversion factor was 0.0292 and they have 0.0274 or similar 😀 And that means top quality lights for plants. If you do some science you would be suprised what lights you own. And sunlight is 0.0185.
The best spectrum for Our kind of plants is balanced. I build My own L.E.D. Grow lights with C.O.B. chips. I use 16- 50 watt diodes ? or Cobs for short. 6- W.W. 3000k, 4 red 660nM., 4- C.W. 10k, and 2- royal blue cobs. I also use 10 watt 395nM. cobs for a little U.V. A to enhance flavors, and resin production. I use 6 of them. My plants respond very well. Resin production increased. Temperatures were lowered, and My electric bill went down about 40% or so. I can still see the color , and condition of the plants leaves to adjust nutrients. I grow totally organically , and brew My own fertilizers, and I make EM-1. I make super soils with 7 ingredients. Lights should be Super also with a good mix of spectrum, not all of one color. So in order of most used on My light formula. W.W. 2700 - 3000k red 660nM., C.W. 6500k - 10,000k, royal blue 440-450 nM. and little 10 watt U.V. A 365-395nM. This covers all but U.V. b and far red. I use a 600 watt H.P.S. still in the center of the flowering room, and 4 T-5 pure Par U.V. A and B for a near perfect flowering/fruiting spectrum. My channel is Grow4Survival on RU-vid My light builds are depicted. I would like to work with a company as a Developer/ Designer. For the fun of it. I love this stuff. Thanks Shane for all of your work, and research. You are helping the People of The Growing Community a lot. Respect....... Joshua Seven Thunders A.K.A. Ivan Quin, and some other stuff.
Green light is most visible spectrum for humans so the least amount of photons are required for the job. It's not preventing a small amount of photosynthesis occurring. Whether the plants 'wake up" and the metabolism changes in not sure.
So it's good news in a way. The higher photosynthesis efficiency light is less power efficiency. Zero sum game or should we make a new efficiency unit wich consider both types of efficiency?
Yes, eVolts absorbed at each frequency from the lowest (780 nm) to the highest (280 nm), broken out by frequency. We would be returning to the correct view of light, e.g. it is a form of Electromagnetic Radiation (EMR), "why?" and therefore subject to the exact same laws of physics as its much-lower frequency cousin--radio. You may be thinking, "why?" Because, in radio, we know how to use frequency interactions well enough to significantly increase the distance we can beam packets of electronic information across, literally, hundred of millions of miles, from beyond the Solar system using, relatively speaking, a tiny amount of energy, to do it with. Surely we should be able to do the same thing with the Photobiologically Active Radiation (PbAR, NOT PAR), we are attempting to beam from our lighting to our plants. In other words, the way we transmit radiation to our plants needs to be beaming just enough at each frequency to maximize signal integrity and "constructive interference" aka "harmonic reinforcement;" without, avoidably, wasting any.
