SIERRA ERA people that don’t smoke think it’s super funny to say anything about weed, even if it’s literally not a joke. I think of it like how middle schoolers giggle over regular words
There's something very cool with the blend of colors in the background from the three generations of grow lights behind Shane that makes for a great visual and a truly classic video!
A lot of good information👍 I usually adjust the lights according to stretch or heat stress, if the plant is showing signs of stretch I'll lower the light and leave it for 24 hours. If it's showing signs of heat stress I'll higher the light and leave it for 24 hours, and a good isolatating fan blowing between the lights and the top of the canopy lets me get the light that little bit closer.
Maybe measuring out and tattching a dangling a streamer or bob-wait line on a string from the light so its a reference to the top of the plant or canopy.
Very interesting video but I really think room environment, genetics and plants different stages plays a big part in how low or high you should go with your lights
Can I just adjust an LED light as low as possible so the footprint appears to cover the plants and then adjust the intensity knob to achieve the desired ppfd based on my iphone using photone app?
I am trying to figure that out as well... I have a ac affinity 400w Ionboards44 and they recommend this n that but for me I have it on the lowest possible setting for light when they are seedling and going into veg.. and let the plant tell me.. they'll start praising or reaching up to the light in a good way not that stringy stretch.
You can use app make sure it's calibrated right a phone camera can only do so much but for budget purposes gives you an idea at least what range you in
Even Conor McGregor? IV heard two woman at least have been compelled. No shade on the Irish or Shane, I just couldn't miss this opportunity to educate/insinuate against the MSM silence and UFC Disney lawyers power. He needs disowned and his bits fed to the pigs.
Could you please do a video specifically targeting how high to set l.e.d. lights as we tend to have to mount led lights higher than hid lights as the led's tend to bleach out the top's of plants due to the light intensity I would suspect. Please elaborate on this topic.
Hi Shane the 1200 par you mentioned is that a good guideline for all stages of growth of a medical grow in other words from seed to harvest I have the cheaper meter you mentioned and I’m about to start using it on my next grow for the first time with your Migro 600
Adjust-a-Wings also make Super Spreaders to go with with their high quality adjustable reflectors which dissipate both light and heat more evenly preventing “hot spots”. Thus allowing for closer proximity to the canopy.
If I was using a lux meter on my phone what numbers should I be showing for best results in a 4x8 grow room using K4000 AGLEX IN hanging them to the right height 🤔
My plants are growing tight and short. No sign of nutrient deficiency, but after 8 wks they are only 12 inches tall….someone has told me to lift my lights and make them stretch….what do you think?
can't say it wasn;t informative......just thought life is more important than watching that all the way to the end. i hope it helped someone who suffered thru it
Hey Shane , can you please test different kind horticulture lights from led tech ? Its a german product . They have different systems . System250 V2 , they have the Zeus 308XT Bord . And its a good Produkt . Different spectrum in every Typ and modules with different led chips . There really good and didnt cost much . Made in germany ;)
Closed tent tests is the way to go when testing lights. But it all depends on your own setup. If your growing in a tent the ppfd readings can go up drastically when closed. Your plants spend most the time in a closed tent. So why not do a closed tent or space test? 🤔 i don't know anyone that grows with only 3 walls and no top... they are either opened or closed..you loose alot of reflective light. I can unzip my tent 3 inches and I get a drastic change on my meter. I'm using 640 watts. 2 viparspectra xs2000s and 1 xs1500 in a 4x4 with tent open..i get 733 on ppfd meter and when I close the tent the reading jumps to 836 ppfd. This is at 34 inches each light is side by side with the 1500 in center. Both xs2000s are set at 75% and the xs1500 is set at 50%...when I jack up the power to 100% on all 3 and close the tent I get a max reading of 1,228... when I open the tent I get a reading of 1000 so that's proof if your growing in a tent be sure to do a closed tent reading and so on....
But light intensity in LED could also burn the leaves without necessarily an increase of temperature, so the method of messuring temperature would be better with HPS?
Anyone !: have a small grow space 1.5 square meters=16.15 square feet. 122,400 lumens using LED screw in bulbs white & yellow. 21 Autoflowering plants.Offhand, in general am i using too little or too much light from bulbs close to the plants but not too hot? Thank you.
To me 122k lumens is way too much for your plants in 1m2, I recommend 400w hps or even better a migro 300 (which I thankfully own) Also which light temperature are u using ? For autoflowering you should better go for high kelvin since the plants have more flowering time than growth time. But honestly, autos are made to be outside in places that don't allow regular plants to grow du to wet autumn or just too cold temperatures. Next time buy some good fem seeds, will be better and not that much harder ;)
Nevermind you have 1.5 m2. Then it seems ok, but 90k would have been more than enough (that's a 600w hps, or a migro 400 which i don't own haha) But still keep those autos for outside please
@@0tb16 Quite.Well, there's the rub. Here at the North Pole we only get 4 hours sunlight, and its a tad bit cold for plants outside. Maybe we will move to Westphalia or Rhodesia.
Measure leaves temperature...so damn easy, yet I didn't figure it out by myself. I replaced CFL with LED, went to full power 100% and started to wonder why my leaves went yellow, lost chlorophyl, and even became white (basilium). Since my growbox was too low in height, I went back to CFL ! Funny, isn't it ? It seems that LEDs are NOT always better than CFL, even 200W CFL.
Is it a small reflector with the bulb deep inside? If it's a relatively narrow beam the intensity is greater directly underneath and you have to raise the light accordingly
Also, 1000 watt systems designed for warehouse settings with high ceilings use narrow beam reflectors and hanging them high results in very even coverage. It's different growing in a 2m high tent
I have 4 small air cooled (small 6" flange hoods) 600 watt reflectors with 95% reflective hammer tone aluminum on all 4 sides. Inna 6x6 canopy. I have to keep them 24 inches above. No lower. And Iam still getting light green leaves. The plants are healthy. Canopy is full. But soon as I put them from t5 veg lamps to the 2400 watt hps room...they lighten from a deep dark green to a lighter green.
Ive got the kingbo 2000w led. I had it 24 inches about the top of canopy but noticed the tips of my leaves were burning and some leaves were feeling dry and papery. Would you recommend hanging about 40 inches ?
Please do a video on the effects of migro cobs into a water column(aquarium w/plants). Would want to see spectral loss or gain, intensity loss or gain, ppfd at various heights... Thanks brother, for all of your helpful info!
Hi, I m using the new citizen horticulture series lpw and lprb ...I can't seem to find a sweet spot. I have 7 50w COBs in 90cm...probably too much. I start at 70cm and finished at 40cm...amazing flowers but the plants seem to suffer a lot too. Do you have any info on these new cobs? Thanks a lot.
He can't say... These are so may variations, type of light, strain, your set up. My opinion, estimate to the best of your ability, but pay attention, for your next crop. The best way to know is by reference and record keeping. There is no absolute, until you have tested.
It pays off on the long run...i haven't paid for a bag of weed in a year. Got started for $200, spent another $150 after 2 grows, set is complete. The lights add about $10 a month to the electric bill.. keep paying for it 😄
I know this video was from a long time ago hopefully still around I have a 4 x 2 x 6 grow tent with a 1000w LED light the clones have been in there for a weekand the leaves are turning yellow am I getting too much light? And if so what size what size light should I get for that size of grow tent
Im having a issue of light range and intensity have a 400w Ionboards44 from ac affinity. .. i used recommend by then n my plants tell me everything long story short hang the light as high as i could on the lowest intenensity.. let the plant do the talking
If led need to be 24"-36" then technology has slid backwards in Artificial Light Sources All our best yields and potiency 25%-34% Still grown with Hps/Mh if LED lights are not set it and forget it then the technology is a waste of time anyway 🤐
Excellent. You've confirmed my current process. The foot tall seedlings are all doing well. I have my light at the top of my grow tent and I'll now come down a foot for a week and check again.
Are lux or FC measurements of any use with grow lights? With LEDs they don't give off much heat so surely that's not a reliable way to suss the height?
Lux measurements ar not accurate for photosynthetic light, they do not measure red and blue light properly. As LED's don't give off too much heat they can be closer to the plants. Your skin is a good guide to physical heat detection and when it is too hot for life.
What about the use of my light rails? My LED's are always moving either north/south-south/north or east/ west-west/east. I've designed a turn style or inverted lazy-suzan that allows me to rotate the whole light assembly any direction I want thus changing the light rails to allow light penetration and never a hot spot or high leaf temp no matter if I'm 3' inches above my plants. How much PAR can I allow them now without damaging cell structure? What are my plants new thresh hold (PAR numbers)? Am I on to something or is what I'm doing a bad invention and just a novelty? They are getting PAR readings of 2600 but its never at that for more than a couple of seconds. The plants do experience time with readings of 200 PAR when the light panel has gotten its farthest from that plant but then they change direction and come back . I don't keep them that low ALL the time because I don't get any stretch. I currently have Plants that are 8" tall and 10" wide and solid green because the foliage is so dense. I just came up with this turn style idea 2 weeks ago and the plants are only 3 weeks old from seed. Long story short is how high of a PAR number can they constructively put to use? Have I just created new maximum yield numbers to strive for?
Fucking awesome idea, man ! I'm thinking about implementing it if you don't mind :P Gonna try a circular constant movement. Or maybe even some oscillation in all dimensions. Fuck yeah ! Tomorrow I'm patenting this!
@@YuriPetrovich LOL Go for it Brother. I hope you make a fortune! It would be easy to automate the turn style so that a slow rotation of the whole fixture is achieved. It's nice to see that someone thinks it has merit. Now go make us proud, or me proud and you wealthy. LOL I hope it does my friend, I hope it does. I just need to know if some new PAR numbers should be applied with this implemented.
@@YuriPetrovich Right on Brother. I'll be looking forward to seeing your results and to see if you have any higher yields. I'm sure they will be thicker, more dense and have a richer canopy of foliage. I say that because mine appear to have these positive traits already. I just need some stretch before between leaf condensation and over crowded foliage becomes a issue. Can't wait to see your data you collect! Peace out 4 now Leonid.
Hi Keith,great idea! I think that the maximum PAR is 1200.Anything higher will slow the growth and maybe burn your plants.I take this number from a video by shane here on the migro channel,but can't remember which one.In these days i'm watching a lot from his channel,excellent educative content.For sure is a video about PAR,maybe the video on the best hanging height,can't remember! ;)
Hi Shane a quick question I have 5 lights 3 are 600w and I have one 1500w and a 1000w, because they are different I don't know what distance I should hang them, my gut instinct is telling me to hang the highest wattage higher up and the 600w lower, any info would be much appreciated please.
A word of caution: Those non-contact IR thermometers are +/- at least 10 degrees Fahrenheit. Ask any competent HVAC guys you know. Then ask them what they use when servicing an A/C system. The cheap one's are not something I would trust to watch over my harem.
Around 18 inches from the canopy. If you see to much stretching, start to lower it slowly until you find the sweet spot you want. And your footprint will be about a 2x2 foot area
Please get some long sleeve hoodies, and always wear them with the hoody up, and wear pants/sweatpants (and sunglasses on). #Melanoma is no joke! And protect your eyes a little with some shades! I love and very much appreciate your content! Thank you!🙏👌
YES! My plants fried under the too-close lights last time just as you described. Tried fiddling with LUX phone apps but keeping Leaf Surface Temps just under ambient room temp may save me this time. I have an IR surface temp gun / baby thermometer that I can use! Thank you!!!
good info!!, but please stop swallowing all the time very annoying...maybe better to drink a beer before you start...but thnx man..grts from holland etherlands..
Exactly why such fixtures are not good for plant growth. You need the entire area above the plants evenly spread with LEDs, not clumped together in a fixture which is maybe 1/4 of the area of the tent at most and positioned in the middle. It's not much better than an HPS bulb that way. Those kind of fixtures are for suckers.
I think just put your Temperature & Humidity Meter probe at the base of your plants and as long as the temperature is between 22-26 your be fine with the height especially if your dimming your leds to 70w at seedling stage and increasing it to 140w 210w 285w as the plant gets more hardy (telos 10 pro mesh) saves on electric and vegg'ing the plant you don't need as much electric or those red leds on. So height varies depending on wattage. I guess leds are slightly different to hid/hps lights but they say plants like a tent to be 22-26 degrees c so if your probe says 25 at the base of the stem your about right.
i guess my chinese led strips idea wasnt so bad...i can put my plants really close and they seem to love it.im gonna reinforce it with a few 10w cobs though so that may change things a little

Thank you!
Are lux or FC measurements of any use with grow lights? With LEDs they don't give off much heat so surely that's not a reliable way to suss the height?
Lux measurements ar not accurate for photosynthetic light, they do not measure red and blue light properly. As LED's don't give off too much heat they can be closer to the plants. Your skin is a good guide to physical heat detection and when it is too hot for life.
how close should a 630w double ended cmh light be? thanks in advance. love your videos
he shows you a couple options to measure it yourself.
What about the use of my light rails? My LED's are always moving either north/south-south/north or east/ west-west/east. I've designed a turn style or inverted lazy-suzan that allows me to rotate the whole light assembly any direction I want thus changing the light rails to allow light penetration and never a hot spot or high leaf temp no matter if I'm 3' inches above my plants. How much PAR can I allow them now without damaging cell structure? What are my plants new thresh hold (PAR numbers)? Am I on to something or is what I'm doing a bad invention and just a novelty? They are getting PAR readings of 2600 but its never at that for more than a couple of seconds. The plants do experience time with readings of 200 PAR when the light panel has gotten its farthest from that plant but then they change direction and come back . I don't keep them that low ALL the time because I don't get any stretch. I currently have Plants that are 8" tall and 10" wide and solid green because the foliage is so dense. I just came up with this turn style idea 2 weeks ago and the plants are only 3 weeks old from seed. Long story short is how high of a PAR number can they constructively put to use? Have I just created new maximum yield numbers to strive for?
Fucking awesome idea, man ! I'm thinking about implementing it if you don't mind :P Gonna try a circular constant movement. Or maybe even some oscillation in all dimensions. Fuck yeah ! Tomorrow I'm patenting this!
@@YuriPetrovich LOL Go for it Brother. I hope you make a fortune! It would be easy to automate the turn style so that a slow rotation of the whole fixture is achieved. It's nice to see that someone thinks it has merit. Now go make us proud, or me proud and you wealthy. LOL I hope it does my friend, I hope it does. I just need to know if some new PAR numbers should be applied with this implemented.
@@keithnewcomb3990 lol Was totally kidding about the patenting, but sure as hell gonna try it out and report back with the data.
@@YuriPetrovich Right on Brother. I'll be looking forward to seeing your results and to see if you have any higher yields. I'm sure they will be thicker, more dense and have a richer canopy of foliage. I say that because mine appear to have these positive traits already. I just need some stretch before between leaf condensation and over crowded foliage becomes a issue. Can't wait to see your data you collect! Peace out 4 now Leonid.
Hi Keith,great idea! I think that the maximum PAR is 1200.Anything higher will slow the growth and maybe burn your plants.I take this number from a video by shane here on the migro channel,but can't remember which one.In these days i'm watching a lot from his channel,excellent educative content.For sure is a video about PAR,maybe the video on the best hanging height,can't remember! ;)
Mate are the PPFD meters on mobile phone any good are they accurate enough please mate 🤜🤛🇬🇧💨
I just want a simple truck with whatever lumens your light is and how many inches above to hang it
Hi Shane a quick question I have 5 lights 3 are 600w and I have one 1500w and a 1000w, because they are different I don't know what distance I should hang them, my gut instinct is telling me to hang the highest wattage higher up and the 600w lower, any info would be much appreciated please.
A word of caution: Those non-contact IR thermometers are +/- at least 10 degrees Fahrenheit. Ask any competent HVAC guys you know. Then ask them what they use when servicing an A/C system. The cheap one's are not something I would trust to watch over my harem.
So what his the Gold rule for Different Wattage`s #or is it up to the Pearson growing it ! Cheers mate
ive got a 1200w led which draws around 300w, how far should i hang?
Around 18 inches from the canopy. If you see to much stretching, start to lower it slowly until you find the sweet spot you want. And your footprint will be about a 2x2 foot area
would i just double the hang height for a 1200W light?
I think 70cm would be ok
i have a lumatek 200w for which phase is which % 25,50,75,100?
Please get some long sleeve hoodies, and always wear them with the hoody up, and wear pants/sweatpants (and sunglasses on). #Melanoma is no joke! And protect your eyes a little with some shades! I love and very much appreciate your content! Thank you!🙏👌
YES! My plants fried under the too-close lights last time just as you described. Tried fiddling with LUX phone apps but keeping Leaf Surface Temps just under ambient room temp may save me this time. I have an IR surface temp gun / baby thermometer that I can use! Thank you!!!
Any estimates on that lux use of the phone apps ?! Seedling/beging veg-end veg/flower?
good info!!, but please stop swallowing all the time very annoying...maybe better to drink a beer before you start...but thnx man..grts from holland
etherlands..
Migro, I have a 1000 watt tolys led full spec light. What distance should it be hung from the top of the canopy please sir?
Strong LED's can bleach leaves and ruin plants. Does the thermometer method prevent that?? I would not think so.
So glad I found your channel. I have just brought a Mars hydro tsw2000. And wasn't sure.im used to HPS.thank you.
HPS grow 🪴👍 badass 😤
times more power. Did the big
switch 💠 from LED lights ❔💭
What size /make of LED lights did you use ? And what size of HPS did you change to . I’ve always used hps but people saying led is the way to go.
Thanks Shane, great bit of info!
Hi explain all nice but very enginering way. What you will prefer for cfl ligt 200w how far the light should be? Thx for help . Stay safe🙏
Look at how high this guy is , I deff want to grow the strain that he's smoking
Light damaged leaves get yellow. But 'unlike' a nute deficiency, they are hard to pluck off.
What about quantum boards? How much lower can you hang them?
Eh and what if you adjust your adjustawing? The second one you point to is clearly set quite taught for deep penetration.
Exactly why such fixtures are not good for plant growth. You need the entire area above the plants evenly spread with LEDs, not clumped together in a fixture which is maybe 1/4 of the area of the tent at most and positioned in the middle. It's not much better than an HPS bulb that way. Those kind of fixtures are for suckers.
you cant eat a steak in a single bite.
you say maximum par should be 1200 but on your website it sais 800. what the correct par then?
Still taking did not tell me any thing a distance would be fucking nice
Thanks Shane, this is fast becoming my favourite TH-cam channel, De Bacco University on TH-cam is very good too.
I think just put your Temperature & Humidity Meter probe at the base of your plants and as long as the temperature is between 22-26 your be fine with the height especially if your dimming your leds to 70w at seedling stage and increasing it to 140w 210w 285w as the plant gets more hardy (telos 10 pro mesh) saves on electric and vegg'ing the plant you don't need as much electric or those red leds on. So height varies depending on wattage. I guess leds are slightly different to hid/hps lights but they say plants like a tent to be 22-26 degrees c so if your probe says 25 at the base of the stem your about right.
Lovely to see an Irish man on TH-cam who know it to a science . Excellent video Shane keep up the good work !!
what about the hanging height of the migro 100?
Minimum 30cm or 12" and 35cm or 14" for very even spread.
Garbage light anyways
This is interesting. I can't seem to find this information for microgreens.
Hello Mike, I’m going to grow mini orchids in a terrarium. How high should I hang my grow lights?
i guess my chinese led strips idea wasnt so bad...i can put my plants really close and they seem to love it.im gonna reinforce it with a few 10w cobs though so that may change things a little
I also have a strange feeling that some products are overpriced. Look for KElvins - 2100 and 6500k are the best pair.
