What is the best grow light spectrum for plant growth
When it comes to growing healthy and vibrant plants indoors, lighting plays a crucial role. Plants require specific colors or spectrum of light for photosynthesis and overall healthy growth.

Professor coming back strong...thanks big homie!
You are welcome!
I can vouch of Shane's lights & his honest opinions.
Both are top class!
Thanks for sharing this.
I understand and appreciate Shane's use of PAR and the sun's spectrum for lighting, and I know the lights work great.
I just think that using phosphored LEDs is less efficient, and more costly in the long run than just using LEDs for the wavelengths required. I have used single phosphor emitters mixed in to my rig, but for rendering, so I can better view and inspect the plants.
Using a couple different blue wavelengths, and like wise red (and deep red, not far red, if you like) will cover most of the absorption wavelengths of chlorophyll, as well as accessory carotenoids. I started "playing" with LEDs 14 or so years ago when 3 Watt emitters were launching everywhere. I commit 30 to 35% of my total Wattage to blues, as it takes more energy to make blue photons... That's pretty optimum for me, based on current LED tech.
If I didn't use colored emitters, I would, and in the future will be using the 12% blue lumiled horticultural LED COBs, which are PHENOMENAL, still.
Thanks for sharing your experience!
The figure at 2:50 differs from the Philips website, which indicates that “the green/PAR ratio is constant at different heights and therefore is not absorbed by the canopy and does not penetrate deeper into the crop.”
Green light (as shown) is not well absorbed so it does actually bounce around more in the leaf resulting in deeper penetration since it is not well absorbed.
My go to for knowledge our hobby 🌿🇬🇧
Thank, glad to have reached this status!
It is useful, that the light on the plants has different spectra, because the plant will use it all for growth.
Another video on the channel for spectrums impact on plants.
thank you :)
Thanks for watching!
Before I watch this i do have to say if I have a few in veg and I pop a couple beans and put a seedling light (blue) over the little ones the veg plants ALWAYS lean towards it in short notice.
I'm running a SF 4000 at 73% normally in a 5 x 5 at around 22" on the veg.
Im usually running around 82-85%, maybe higher until I see possible beginning leaf burn and back it off.
Photos...
And again, thanks for great interesting content.
(22" seems to get my PAR in the correct range veg wise)
Any comments after watching the video?
Sounds like a debacle to me 😊
Not quite as complicated as it may seem.
Unmentioned, but important to cannabis growers, was the chart at 5:20 which shows increased oils with UV light.
Nice attention to detail.
I read quite an interesting research paper where they compared HID (HPS) lighting against modern LED lighting (Full spectrum) and the results were interesting. HPS actually produced more inflorescence, but less secondary metabolites. It's hard to say what caused the difference though? Was it the increased red light and reduced blue light that caused the plant to grow more tissue? Or could it be the subtle differences in UV/FR lighting?
May be this DeBacco University video can help you out... ua-cam.com/video/hZiAzcYdDsM/v-deo.html
Is green light produced with a full specturm LED plant grow light?
The seedlings just emerged ( with the help of DeBacco U.)
I have a 'Good Earth' 2ft adjustable LED grow light with red, blue & white switch/buttons and a light diffuser.. It offers various option combinations: all on, two on, one on etc...). I have it set to 'all on', as this is what the 'Good Earth' growth chart indicates for seedlings.
I believe this is the full spectrum setting. However there is no information to support this in the literature. Am I correct in thinking this supplies green light if it is full spectrum?
Thank you and your team for everything you guys do & thank YT for no commericals.
Green light can be used in part by the plant though not at a high efficiency, however it does help the grower see the plant true to type.
I use a small green light in the grow room in case I need to go in and do a quick task, but once i forgot to turn it off and the bud growth stopped. It took a few weeks for the flowing to resume.
Green light good for short term.. "have to do" tasks.

Is it though?
That's a generalisation, I expect Bros to tell each other while it leaves me with a bunch of open questions, like of which wavelength is that "green", which is ok, and at which intensity can that specific light source, emitting what we perceive as "green" overall, fire its photons onto the plants safely? How long is a time-frame of "short" to do so in this context, at which intervals can it be done and to begin with: what kind of "have to do task" could unexpectedly and unavoidably occur in the dark, that _really_ makes immediate action and the correlating risk of interrupting that crucial half of the day necessary?
How high is that risk of interruption with a green light source specifically, considering the extreme low amounts of light needed in general to wake hemp up? How do plants' genetics factor in (not only in sensitivity for light but also the likeliness of severe consequences to occur, like said "weeks to resume flowering" (with, I assume, severly reduced yield) or ladies growing sacks, ruining everything) and how can a risk be assessed at least vaguely but with more precision than only that general assumption, that _it's ok for short?_
Is there up to date science beyond assumptions and personal experiences to make an informed decision to take that risk and for what kind of actions?
Is all that "green light's fine" backed by any actual experiments and/or more sophisticated hypotheses than that catchy but obsolete one, that wavelengths within the green gap, where absorbtion by Chlorophyll A and B is not very efficient, aren't processed by the plant at all, discarding the minimal amounts needed to induce photosynthesis from darkness but also leaving out ß-carotene, which absorbs light of a good part of the green spectrum quite well?
I strive for optimization all over and considering that a disturbance of the night-cycle begins in areas of nanomol/s and may cause pretty ugly or even fatal consequences, which come creeping, subtle and with a time-delay on top, I'd find it pretty annoying process to optimize such a possible disturbance to be harmless. It would need pretty solid research on that topic to convince me that it's a good idea to do *any* "quick task" in the night time under illumination, green or not, instead of just planning ahead a little and simply do any expectable task within the twelve hours of the day, which were freely decided before to have the lights on for the grower and the plants (mainly the plants!) to do stuff.
IMO, even emergencies, which _really_ need immediate action in the dark, don't justify to spend moneys for a green lamp, promising intriguingly easy and seemingly harmless access within the 'forbidden times" (we all like to do the forbidden stuff, right? 😂), as those emergencies can be taken in consideration beforehand and an opening of the room at night times effectively prevented! With stuff as accessibility for the vent from the outside, which is separated enough for regular illumination ... add switches for the fans to kill them in case they're going nuts - until the lights turn. With timers, power supplies and stuff accessible on-top, you just have to tie everything what could fall on the plants nice and tight and I can't think of a single reason any more to turn into an *Emergency Bushdoctor* at night.
so, the second from the right Blue 14 Green 45 Red 41 and Pink 0.8 would be good for indoor grower's ?
All can work depends on what you are growing and also the PAR of the light reaching the plants.
Hi! I have deficiency problem that can be seen in the leaves.. From picture of deficiency pom blogs I cant realy decide wich one it is.. Do you know if there is someone that offers the service, so I can send in pictures og my leaves?
Try this DeBacco University video... ua-cam.com/video/ZTE-YCNWC8s/v-deo.html
dudeee.... universe fr giving me signs, i mean, i found out migro couple weeks ago, he had 98k subs, i tought damn, great man, im doin my own diy led bulb grow lamp, this method was in his channel too, but, i also watching your vids (today i watched bout breedint, i got one landrace plant seeds from one granny, and she growing them i think so whole her life, and i bought some autoflower, i have a idea to cross them with gorilla glue, or northen lights to see whats poppin) but when i saw this video, i was sweety shocked, with what dude you collabing.
Thanks and glad to help... trying to spread the word;-)
You mean "heirloom", not "landrace" seeds. Landrace are wild, uncultivated. Heirloom are cultivated and continued from wild seed. There's a vid on it in the DeBacco list.
@@michaelcarey9359 i mean landrace, that were taken from wild, and cultivated in specific climate
😶🌫️👍🏽
Thanks!
I've known about this since about 1980
and yet not a single video on this included on your channel...

Maybe you can clarify exactly what you're implying
