Grow Lights: Infrared 101

[@MassMedicalStrains]

I love this. I hope there's more of a focus on the positives of IR... I know many people are used to fighting the heat, but now with LEDs we have a new problem, not enough IR and many growers run into nutrient deficiencies because of the lack of IR spectra with LEDs especially in cooler areas! Also the changes in genetic expression!

[@JebGardener]

I like those spreaders and I don't like those spreaders.

[@Cannanadian]

102 please, sir. :) Thank you for the time you take making these videos.

[@Just4Growers]

+Cannanadian Jay Thanks Jay - def a topic that bears deeper investigation! Just scratching the surface here. FLIR just released a better camera (plug in for iOS / Android) so may well invest!

[@LowLightVideos]

5:15 vs. 6:00 - Pushing your bulb in is necessary, better performance and penetration is the way to go - put a short plant directly under each bulb to increase the lamp to plant distance in the hot spot, or use a Rail Mover to increase the penetration and evenly spread the heat and light. Use CO2 and 'GreenUp' liberally.

[@skepticalgenious]

May 2022 led lights have made massive improvements. UVA 380nm is common near IR 730-760 also. Plus red blue green which looks sunlight white 400-700. Still hoping to see led hit the IR 700-3000nm. But technology has improved a lot since 4 year's ago when this was posted.

[@Just4Growers]

Thanks for your comments and insights amigo - an updated video on LEDs is in the works.

[@skepticalgenious]

@@Just4Growers oh sweet awesome... I am a noob learning about light myself. Light technology is awesome.

[@nicholasroos3627]

If they run ovens on IR my bet is they sure don't use LEDS. Anywho.

[@goldleaf889]

I just wanna know is it ok to use a small infared heater to heat up a basement where I store my medical cannabis. I bought a cheap one at Home Depot for 75 bucks. It sometimes gets real cold. Will infared do any harm to my cannabis? I store it in a cvault. Thank you

[@K_Nasty]

I have an led with ir diodes. It is dimmable. If I want to "put my plants to sleep " faster could I just turn the light down for the last 10min or so?

[@Mickhealthy]

So the IR is vibrating the water molecules, increasing the heat load so should the target AC temp be based on plant leaf temp? and how do you factor CO2 into this?

[@jdmichigan8824]

Good info. I was wondering what should be the dominant light source. It seems the newer LEDs are moving towards white.

[@Just4Growers]

JD Michigan I'm testing a variety of fixtures right now, some with phosphor-coated (white output) diodes and some mixing it up with monos (colored diodes) - certainly the whites are easier to film with! I'll be (finally) publishing an LEDs introductory vid soon.

[@ptxarptxarov3830]

Great fast phase video with no any side bullshits. Good job man!

[@a807440]

Love the videos as always and have continued to enjoy your tongue in cheek humor in regards to the cannabis growing community! Keep it up, never slow down or we won't get as much info into the video!

[@Just4Growers]

+a807440 Thanks amigo - glad you and all my brothers and sisters growing all sorts of plants glean something useful from the vids. Hopefully something in there for everyone - let's have a group hug with Mother Nature! 1,2,3 ... awwwwwesome!

Hi Everest, I'm so glad to have found your channel. You make superb videos! Have you put out any videos on defoliation? I would love to hear your point of view! Please keep it up!

[@mikesatomic-skier7161]

holy, gotta love the knowledge spreader like urself everest, u teach us so many things with ur videos, its amazing, im truly grateful!! i love the quickness and the actual science u put behind ur videos, really great effort for us viewers, gotta love that too... i would love to see u testing some new led technology like the chilled leds and some of their rivals. thanks again for the upload and ill be waiting for the weekly (2 fingers crossed) updates LOL cheers and stay frosty

[@AM-rp5rr]

Everest your my favorite grower on the tube bro love the indirect approach for people like me with the munchies thanks

[@Just4Growers]

A M Thanks amigo - I enjoy making these vids and especially appreciate the love and support I get from growers who don't necessarily share my love of capsicum. Enjoy your late night snacks! I know I do.

[@methisguy2693]

can a camera in a grow room effect the light cycle? my camera has night vision aka infrared

[@CheesieGamer]

Everest Fernandez Hey... another great piece of info for our library of knowledge. As per your suggestion i got the laser thermometer (santa send me a PAR meter!) amd confirmed the following... Room temp is 24.... inside thw tent 27-28... and the top cannopy of my heavy annual light loving plants is about the same as the room (tent) temperature. I am using 2 300w leds inside a 4x4x8 tent... got a 4 ' extractor... the constant pattern is the tent will always be 3 or 4 degrees higher than the room where I got the tent.. The manufacturer claims their LEDs got IR diodes... but I dont know.... cool thing is that plant inner temp is at no more than 28 C. I read in a couple of websites of some LED manufacturers that plant temp should be 28-30... given the reason for keeping the room temp higher than what it would be needed if u were running cool HOT DE lights like the ones u got. I am just a newbie learning feom the pros. pura vida amigou!

[@kazimir8086]

Does your room gets smaller and smaller after every new Video?

[@Just4Growers]

Stop it, you'll give me a complex :)

[@PaidinFull2024]

InnocentPhoto Lol ^^^

[@punktVail]

Is it worth, using an incandescent light bulb, if my growroom is slightly too cold? Currently i'm running about 120watt leds. I've got enough space for 2x e27 bulb fixtures. There are 2 different types of light bulb available: 60watt and 100 watt. atm im still in veg but if they surive the transplant shock i will switch to bloom(in about two weeks). sry for bad english : > ) Any suggestions?

[@opticledgrowlights2092]

We would like you to test our CREE COB LEDs on your channel.

[@autogarden1432]

Cree chips produce less heat, a good choice for COB

[@joshp9964]

Im looking at getting a 4x2 grow tent. Was thinking of getting two 300 watt viperspectra $80 a piece led or one of there 600 watts $180. Ur help would be appreciated. Thanks.

Truly superb video on a topic which when I read the title was skeptical about how much useful information I would get from it.. why I even slightly doubted you I don't know 😅 your videos are always quality👌

[@jlucasms.college2187]

Love the video!! This is the kind of info thats a blessing to find. I'm new to indoor grow and hitting the learning curve hard. Thank you brother!!!!

[@Just4Growers]

Jay Lucas wow - such awesome feedback. I made this channel with beginners specifically in mind so this is great to hear. Always happy to try and answer your questions. Heat control tends to be forgotten about by novice growers - it's so important.

[@mohsenaghdam3136]

Perfect Everest👏🏽 and what about CFL lamp is there any IR in this lamp? Or just we can find it in HPS lamps ..Thanks for your greate Video❤️❤️

[@Just4Growers]

+Mohsen Aghdam Yes, CFLs emit IR too - but not so much a huge spike like HPS.

[@kingkoopa420]

Great video like always Everest!!!! Keep them coming amigo always waiting for more.

[@Just4Growers]

+Sir. SmokAlot C Always happy to hear that my vids are useful, especially to my green brethren. Peace and happy growing amigo, Everest.

[@macernotis]

Hey! Awesome video as always! I wonder what's your opinion on "umbrella style" (?) reflectors where the bulb hangs vertically in the middle. They used to be popular in Europe but they almost left the market nowadays. They are hardly advertised and i never see people talk about them online. Cheers!

[@jordykingstongrows3639]

*Superb Video* I recently replaced my 1000w Gavita light Reflectors to the wider spreading Gavita W150DE reflectors to help with issues of not being able to raise them high enough which I thought was basic heat stress or light intensity.. this video just *cemented* for me that I made the right decision as its the IR radiant heat that was probably causing the most problems if I understood what you was explaining correctly?

[@Just4Growers]

Jordy Kingston Thanks Jordy - yes, the small "deep dish" style reflectors can trap a lot of heat a re-emit a lot of IR - as well as the fierce 1000W DE-lamp itself which, if not placed far enough away without anything to deflect the IR, is more than capable of overloading IR and creating radiant heat issues. Good move!

[@DJTechnoboom]

cool thanx, do they work for HPS also or only the newer style light's that you have?

[@monicasantos9047]

U make it seam as if IR is just to heat up your plants. It's not. It's not like u to leave out important information. We know that blue and red light is optimal for plant development, but research conducted in 1957 has shown that combining blue light and red light with far-red/infrared light (700-760nm), led to an increased rate of photosynthesis due to the Emerson effect. The protein Phytochrome is the only known receptor that is sensitive to far-red/infrared wavelengths. Plants use Phytrochrome to regulate when a plants is to switch from vegetation state to flowering, and the time of flowering, due to the length of daylight or exposure to artificial light.

[@gangagrow5722]

Like 3rd time watched and still discovering good things on this vid (kind of slooow here, 2nd language for me). What’s about infrared performance on LEC tech, like the 315 or 615 you had reviewed from Sun System? Thanks Everest

[@elliottdebell7783]

Very interesting video

[@tripzero0]

Here's an idea, if you are worried about the IR that water absorbs, why not put a water "filter" below your light? A one inch thick box of acrylic filled with water should do the trick.

[@Ryutai7]

Always been really interested in this topic. I often forget that it's *all* light that generates heat, not just the infrared variety. Thanks for the reminder and cool experiments!

[@prmikey]

I love your rap style. Bars and bars and bars 🔥🔥🔥

[@vojtator]

Do you have your own worm farm?

[@Just4Growers]

I have a small vermicomposter in my yard .... but nothing substantial. Why do you ask?

[@vojtator]

So I can find out if it is possible to beg for vermicomposting video.

[@tripzero0]

All absorbed photons contribute to heat. One should not think of IR as heat, but all absorbed photons instead, visible or otherwise. For examples, microwave photons are not IR but still heat things up so effectively, we make ovens that use them. UV photons are not IR, but they are energetic enough to break up carbon chains, cause burns, and even destroy DNA bonds.

[@nicholasroos3627]

Well coupled energy is the key factor here.

[@Watches4You]

Are there super spreaders or other mitigation tools for air cooled reflectors? Very interesting and educational as always. :) Also, I'd like to see a video with advanced techniques for difficult to germinate species. I'm trying to do Lavendula Dentata and some edible fruit varieties.

[@Just4Growers]

Thanks for the difficult germination topic idea - I'll add that to the list! (Currently 30 vids on my todo list!)
