Very elegant experiment in its simplicity. Well done! I'm convinced that angle of incidence = angle of reflectance. Very straightforward demonstration.
I’ve seen another vid that proves the opposite but they used two grow tents one white ,one Mylar , the white one was better at light reflection and didn’t create hot spots in the grow space.
I completly understand, thank you so much for this video, in over a decade of growing this is the first time i have encounted this factual info, you have a great attitude towards this and these videos help give us customers confidence in your knowledge...if this is how you work in ref to reflective materials...the lights must be on point! Thanks man!
I’m looking to get a grow tent and I’ve been lucky enough to stumble on the thought of which reflective material is best, black dog led just released a side by side test of gorilla grow tents vs budbox and I was wondering if you could let me know if that review/test is deceptive or not.
I think this test makes sense from a standpoint where only the walls are reflective. In such a case it would make perfect sense to want the light to be reflected in a directional fashion towards the plants. But what about where all reflective surfaces were covered in reflective material? In such a case the light bouncing off the surface at angles not directly in line with the plants would hit other reflective surfaces and would eventually be reflected to the plant canopy (assuming a high rate of reflectivity). This is the theory (at least how I understand it) behind things like matte white paint and Orca Grow Film. The whole point is to diffuse the light so that you eliminate hot spots and more evenly spread out the light/PAR. I’d love to see you guys do a test video where you lined the entire grow area with the diamond Mylar, Orca, matte white, and maybe one of the other brands like Panda. Then took PAR measurements throughout. Not saying you still might not be correct that the diamond Mylar was better, but at least that would be a more fair comparison method based on the theories behind diffuse vs specular reflective material. Thanks for the video.
It would be nice to see the test from a center point. You are getting only a reflective comparison, and I think something can be said for diffusion capabilities
Just demonstrating the principal that supports tests that show a shiny reflective material performs best getting light down onto your grow. Diffused light is useless if lighting the top of the tent.
@@MIGROLIGHT Hi shane now if you did the same experiment with the diamond mylar VS flat mylar the flat mylar (it will contradict you'er other tests) would be more reflective and if you put a mirror in the test that would reflect even more than paper or any of the mylar products so whats better? reflection or scatter? white is 99% reflective in All colours of the light spectrum, but defuses all that light in all direction,s "the mylar best is 97% reflective but not 100% of all colors thats why it looks gray or silver " nothing can reflect light better than white sit in a dark room with torch same size piece of white paper and same size piece of mylar and see what ilights the room up better ? ua-cam.com/video/3ijPn9PjQ90/v-deo.html and this video says white is better ua-cam.com/video/zL_yj_b-rHg/v-deo.html
Thank for this experiment. Have you try to place the light source in different places or project with different angles, will it change the "arch" form of the reflection that's produced by diamond mylar?
mylar coated plastic film is definitely more reflective than white paint when its new but the grow room environment degrades the mylar very quickly and so after a few months the mylar becomes almost transparent and completely ineffective as a reflector and in my experience needs to be replaced between every crop.it is much easier to apply a fresh coat of paint to the walls once a year than to replace all the mylar several times a year.so for most growers white paint will give you better results in the long run
How are you liking bud box tents? They use white walls I thunk? They claim better reflections then then diamond mylar walls in the GGT. Can you buy into/ agree with that claim made?
hello he same test with the homebox by + or orca will be different because more reflect that the matt white. white would be better for led ... and would have better growth under can you confirm it ? thank's
Paper allows light penetration , so the experiment results are flawed ,,, flat white painted surface would yield different results than just plain white paper
You are comparing mylar to white paint essentially. Concentrated light is bad for the plants. You want to diffuse the light as to avoid hotspots which can damage the plants, especially young seedlings.
I'm afraid we have to disagree. Just use the diamond Mylar to avoid hot spots. Silver mylar is more effective email than white in all tests we've done, even with orca grow
MIGRO how about white Orca paper that is supposed to be far superior than white paint on a wall. What are your thoughts on the white Orca paper if you have ever used it? It's rather expensive that I do know as I've gotten 75 feet of it in the past and I've seen it to be better than the mylar that I have inside my tents.
Agreed, concentrated light IS what causes hot spots. I think we could all agree Mylar is better and more reflective than just white though. I don't think the results of this test tell us how much it is better though because of using white paper as comparison. White paper is not the same as white paint or other white surface. No one uses paper to reflect light and paper is different in texture, brightness and how much light actually passes through the paper instead of reflected. White surfaces of other materials and textures would give somewhat of a different result I believe. Having said that, it is a good demonstration on why Mylar is better and I surely respect and appreciate the info in this video.
Seems to me that this video demonstrates exactly what everybody says about mylar is that it creates hotspots. It is well known that white reflects light the best
How about the specially-designed Orca paper which is I believe 11 layers thick and somewhere around 11 ml thick as well. It reflects light like snow I've used it for a couple years inside my vegetation grow room and when you put the light on a wall you cannot see where the light comes out on the wall but if you put the same light against the mylar you can see the actual reflection of the light in the mylar where it's diffused in the Orca paper. What's your thoughts on Orca paper if you have any experience with it?
There is a previous video that tests orca. Basically it doesn't work as well as silver mylar. There is another video and blog on the website explaining why. Thanks for the comment
MIGRO well that's reassuring that the cheaper material works better than the expensive Orca paper and I'm a bit embarrassed that I bought the 25 and then it $54 of it thinking it was better than the mylar. Thank you for updating me, and I will look around for the Orca paper blog you're talking about.
Please see the comparison of that light and the MIGRO 100 here: ua-cam.com/video/dbJHFkDX4AA/v-deo.html. In short the MIGRO 100 ouputs 60 % more PAR light with 20% less power consumed.
Hi, thanks for the suggestion. Panda white sheeting is the same as matt white. It is not directional, it will diffuse the light and not perform well in a grow room situation. We may try it though, just to prove the point!
orca film company is known to film live demonstrations at expos using their Orca grow film in a side by side comparison to diamond reflective Mylar grow film.... in the youtube videos it looks legit, but i saw their booth at MJBizCon and they had the mylar diamond reflector material UPSIDE DOWN to send light back upwards, away from their PAR meters i pointed it out to the rep there and he said i was wrong, that the mylar reflective diamond material could face any direction and still reflect light. i tried explaining to him that the indentations made are directional, and that they have installed it upside down so the light goes UP and he just ignored me and started talking to someone else Orca is a totally sketchy company
Please see our older videos of PAR measurements taken with 4 different linings, silver Mylar, white mylar, orca grow etc. The white finishes diffuse the light and it is reflected back up the top of the grow tent and the Mylar directs the reflected light better.
Shame the Dammed things are so hard to get clean and oh so fragile... Even the pricey ones are Junk when it comes to constantly keeping it Clean... They all fall apart in the end... Peace
Your nuts if you think this test is fair. Fist of all you used matt paper. Second of all the par meter was cleary an inch further away from the third reading on the matt finish then the mylar reading. Look at where the the distance of the block on both readings using the whole par meter as a reference. Lol.
You really think your experiment is valid, I surely don't!!! Also, the UA-cam comparison said, Matt White Paint was better that Cheap Shit Mylar, not Diamond Mylar, pay attention!!! 😳😲😂🤣🤣
Very elegant experiment in its simplicity. Well done! I'm convinced that angle of incidence = angle of reflectance. Very straightforward demonstration.
Why use paper thou?? Why not panda film or a material used in a grow tent that uses white for their reflective material.
Yeah. Big study mishap
You are very kind to share your knowledge. I enjoy watching your videos and learning. Thank you for helping me.
Youre welcome. Thanks for the comment😀
I’ve seen another vid that proves the opposite but they used two grow tents one white ,one Mylar , the white one was better at light reflection and didn’t create hot spots in the grow space.
We knew this over 30+ years ago. I'm so disappointed that the indoor growing hasn't changed. LED lights are the only improvement.
I completly understand, thank you so much for this video, in over a decade of growing this is the first time i have encounted this factual info, you have a great attitude towards this and these videos help give us customers confidence in your knowledge...if this is how you work in ref to reflective materials...the lights must be on point!

Thank for this experiment. Have you try to place the light source in different places or project with different angles, will it change the "arch" form of the reflection that's produced by diamond mylar?
Any chance of an updated video featuring different types of white paint?
Additives like titanium and barium can increase reflectivity.
Thank you. I am trying to decide which reflective surface to use. This helps.
I wish someone could compare homebox par+ vs secret jardins expensive topseries
mylar coated plastic film is definitely more reflective than white paint when its new but the grow room environment degrades the mylar very quickly and so after a few months the mylar becomes almost transparent and completely ineffective as a reflector and in my experience needs to be replaced between every crop.it is much easier to apply a fresh coat of paint to the walls once a year than to replace all the mylar several times a year.so for most growers
white paint will give you better results in the long run
How are you liking bud box tents? They use white walls I thunk? They claim better reflections then then diamond mylar walls in the GGT. Can you buy into/ agree with that claim made?
Could you test something like your Aray 8 in a tent like The white Bud box grow tent vs a normal mylar tent?
hello
he same test with the homebox by + or orca will be different because more reflect that the matt white.
white would be better for led ... and would have better growth under
can you confirm it ?

Hmmm, would like to see you do a proper test with your array lights , say gorilla silver tent vs pine labs white tents 🤔
Exelente video amigo!!
What if we use a mirror in the grow tent?
Reflective vs refractive

I have seen a vipar 300w in action what kind of yield increase does ur fixture the smallest one offer against the vipar

But, paper absorbs light? panda film would have been far greater.
Cool demonstration 👍🏼
39 would be 300%.
33 is 254%
True. Sorry for the error. Bad rounding up I'm afraid
I looked for some diamond mylar on the internet and there was like a normal one and one called lightite. What's the difference between those two?
Mylar is a generic term for aluminium coated plastic. Normal is good to use. Preferably with the diamond pattern to prevent hot spots
Great bit of info👍
But have you compared it to panda white sheeting
Hi, thanks for the suggestion. Panda white sheeting is the same as matt white. It is not directional, it will diffuse the light and not perform well in a grow room situation. We may try it though, just to prove the point!
MIGRO thanks for the reply iv seen conflicting tests on UA-cam that say white sheeting reflects better. Also panda sheeting
orca film company is known to film live demonstrations at expos using their Orca grow film in a side by side comparison to diamond reflective Mylar grow film.... in the youtube videos it looks legit, but i saw their booth at MJBizCon and they had the mylar diamond reflector material UPSIDE DOWN to send light back upwards, away from their PAR meters

Orca is a totally sketchy company
Bangin Bearattacks panda i meant my bad!
Orca Grow Film rep here. I don't know what you thought you saw but we have never attended MJBizCon. Would love to know who you saw doing this demo.
He card is further away from the reflective surface on the second test.
You are my expert✌️
mat white is panda film ?
Info starts at 3:30
Love your lights I would so love to do some grow offs with one against my LEDs!! Would deff be super dope!! Growerzluv
Thanks. Can you email me and let's see what we can do? Contact Details on the website.
No one will paint his room, I wanna know whether mylar is better than white PAR+ by Homebox.
Yes
@@MIGROLIGHT That's insane info... Kinda hard to believe Homebox would keep pushing their white par+ when mylar is better... and cheaper...
Please see our older videos of PAR measurements taken with 4 different linings, silver Mylar, white mylar, orca grow etc. The white finishes diffuse the light and it is reflected back up the top of the grow tent and the Mylar directs the reflected light better.

Thanks, great video, mylar it is...
Thanks. Please share. It's a shame every grower doesn't know this info
Who is Matt White lol
King Dolla He has a brother named Dana White lol.
All for one extra Trichome a plant
