[@highdrogrower5007]

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.

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.

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.

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?

[@jacobmiskell676]

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.

[@jacobmiskell676]

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

[@valueape888]

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!!!

[@eduardocampos5989]

Any estimates on that lux use of the phone apps ?! Seedling/beging veg-end veg/flower?

[@skippingtax2178]

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

[@jeanninegrant5959]

as close as is possible. put your hand above canopy have light lowers til you feel to much heat, light movers are a good investment

[@НовиСадСрбија]

Leds are not problematic about heat but about light intensity

[@paotg0864]

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?

[@souramnesia-cp3hs]

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....

[@ForPropertyInvestors]

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.

[@adamwalter2573]

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.

I love how high you are in this

[@TheShleafHerder]

Had to review this one always great info Shane thanks a bunch

[@torrielandsman4625]

I've noticed that you never use parabolic reflectors! I use a parabolic reflector with a 1000w HPS and find that I can put the light as close as two feet above my plants depending on the strain, sativas seem to do the best with the lights less than three feet away. also I noticed you don't use defusers with the adjustawing any particular reason? they really cool down the hotspot and allow the light to be closer to the canopy! I believe that LED's have their place but if you want to be productive nothing replaces metal halide and HPS for growing hemp.

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

[@rickwhite9748]

Can I use an HLG Scorpion Diablo for seedlings? It's hanging at 7ft from the floor.

[@arahant69]

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.

[@keithnewcomb3990]

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?

[@shamanbeartwo3819]

First thing you need to do is check is how far above those clones you have the light. That is a lot of light for a 2x4 tent and if your LED is closer than 36", I would expect it to burn up pretty quick. I have 600 watts LED in a front closet that is not quite 48" wide where I grow lettuce, basil, jalapenos, cilantro and if I go less than 36", I can expect all of the seedlings and greens to just dry up. The lights are 19" above the top of the jalapeno plant and it is going crazy. With flowering cannabis I have gone down to 12". I have used 3 different brands of LED and its pretty much the same.

Let's assume that I have a light that has an average par reading of 900 over a 2x2 ft area at 24 inches and a average par reading of 900 when dimmed by 50% and lowered to 12inches. With all other things being equal would I yield the same at the end of flowering in both situations? Thanks in advance for your response. 😁👍

[@alcurtis93]

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?

[@MIGROLIGHT]

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.

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.

3)_600w on area 4'x8' are better. than 2)_1000w on a4'x8' area more luminary less cost

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

[@curiousfiend1169]

@@slum3947 could've been a heat issue maybe. Is the ventilation adequate?

[@oldpondfrog788]

Eh and what if you adjust your adjustawing? The second one you point to is clearly set quite taught for deep penetration.

What about 400 w hps still 40 inches from the seedlings?
