nice to see that even the cheap reflective material is better than not using any. great test 👍to show how much a reflective surface is really needed
Bro literally this is exactly what I was looking for thank you @MIGRO
Right? Like literally EXACTLY what I was looking for, and it's the second video that he hits the subject bang on for me, great content my dude, great content. Oh and Thaaaaaaaank you for the info o/
Hi. I started growing about 2 years ago. I was wondering if u have ever checked mirror reflection?
Mirrors. Aromatic Cedar slats on the floor, sections of, or full size of your space mirror. I have the shiny mylar in a closet and a 3x3 mylar tent.
First of all thank you so much for your passion and honesty. I'm researching the market to find out what the latest and greatest is. No matter what choices I make I will find a way to help support your channel either through a donation or a purchase from your site. I am considering making my own lights LED strips extruded aluminum I'm going to check out your site right now and see if there's anything that I can possibly use. Whether my purchases today or many months from now I just wanted to say thank you for being so thorough and so helpful. Thanks again.
Very useful and elemental video thank you. I will continue with the white lined budbox pro even though silver would be better, just because I find silver hurts my eyes. Good info like this allows people to make their own decisions.
Just built a new grow area a 6x6 multi tiered twelve foot tall cielings and I plan to maximize area with shelving for plants stages I needed this video thanks!
so why the heck are matt white rooms getting higher yields if the silver here is showing better results ?
Matt white my personal choice on a small grow room shows any foriegn contamination dust, dirt, bugs easy to clean no hot spots.
and mold and fungus you need to worry about, PM and botrytis. Need something that is washable
@@SuperCanada89 from what I understand, using a mold resistant paint or bathroom paint helps.
Diamond its easy too. No hotspots
Once and for all. Thanks, numbers don't lie, just people do.
Awesome way to demonstrate the results. Thank you a ton.
Orca sheeting.. 20 plus years of gardening has proven this to me 👌
Thanks diamond Mylar is my choice for first grow
I moved to a smaller place and have no room for my 2.5 x 5 ft grow tent. I made a small pvc with cardboard covered with tinfoil grow area and now. Might just cut the tent up and custom make walls now.
Excellent test. I had always thought matte white was the way to go, but you have convinced me otherwise.
I've had pretty good success using orca paper. With almost no hotspots and incredible reflection. The only thing I don't like about the orca paper is how expensive it is. And when you use it as a flooring it delamination within about a year. However on the walls it works great.
This video got me curious about reflectix vs these options. Mylar and painted boards work better than reflectix from what I've read. Thank you for the informative video. I guess I'll make my grow tent out of some mylar and scrap wood or pvc
mirrors
@@tigrehermano hmm is that one of those things that makes complete sens when you hear it and then theres some weird reason it don't work
muy interesante las comparaciones de papel para reflactar !
Would be interesting to see the results putting the reflectors on an angle towards the light?
...I dont understand ? Why isn't anybody using reflector panels inside tent near the plants ?...A.C.Feuerhelm
Thank you sir, this helped me to choose a reflective material for curing my 3D resin prints. 😁
Thanks, timely advice. I appreciate the detailed presentation. I heard back in the day matte white
was best. Now I know better.
I would like to have seen the results using mirrors
Mirrors don't work as good as simple Matt white paint,sorry bro
the problem with mirrors is that the light has to pass through the glass to hit the reflective material. then pass through the glass to get back out to the plant. so it absorbs too much of the PAR value you need.
good ol tin foil is cheap and works wonders. (the shiny side) .
@Trousersnake Pliskin your names awesome by the way... escape from new york was fkin dope as fuck. i use tin foil and my plants get way more light then they need anyways.. so i dont feel the need to try and maximize the reflective area like with mylar or paint... tin foil is great. and that whole "hotspot" crud is a myth
For people on a budget, I'd suggest trying aluminum foil with a thin layer of white paint or primer over it. Extremely reflective, lets zero light through and doesn't cause hot spots. I'd guess it pretty much rivals mylar in reflectiveness at a tiny fraction of the price.
Just got 4x2x6'11 Gorilla tent, 1640D diamond mylar. Worth every penny
How would roll aluminium foil glued to a flat surface to reduce wrinkles work? Thanks for your great videos and your responses to questions.
Nice to see 'back to basics' still has a place.
Just wondering if you could get ahold of “silver board” rigid insulation and get the reading? I have to insulate and reflect in something.
I went and bought that car front windshield son reflector stuff it looks just like that stuff they use to make heating & air duck work but i can use that stuff where i couldnt afford to order the tent cause i was already ordering the seeds so i figured by getting the pvc pipes to make my tent out of would be a cheap easy way to have one finally lol
I’m using the Mylar stuff but it was a emergency blanket so it was all folded up so it s not completely flat so it don’t get hot spots
You did the white plastic or panda film similar to the matte white paint, but you didn't use orca the white canvas material. Then because this is 3 years old, not sure it was around but the plastic paneling dps. Diversified panel systems.
Could you do a test with the Orca paper I'd be curious because their claims are pretty high I have used this before with good results what would be very curious but the comparison thank you
Great video! I’m slowly getting an education on what I need to do for my plants.
wow this videos are really amazing and helpfull, omg I really appreciate your efforts and your will with intention in making tests, thank you very much again
I USE A REFLECTOR TYPE MATERIAL USED UNDER TUNG AND GROOVE HARDWOOD FLOORS, LOOKS IDENTICAL, ITS CHECKERED AND REAL THICK W NO GROWROOM PRICE
I recommend Orca reflective material. It's white on one side, black on the other, and has great diffusion. I got noticeably bigger yields over Mylar.
Orca, eh?🤔 That's the third time I've heard this name brought up. I'm about to go on a Google hunt...
Orca is five times more expensive. Are you sure it's worth it?
@@Санчес-я1т it is expensive. Anything that is white with good diffusion will work great 👍
Could you do a par test for the topolite tent material? Says it's 600D 96% reflective mylar material, but your tests will have the real say...
Thank God you did this B4 I wasted money on mylar
Someone did a test on RUclips that showed plain old aluminum foil had better reflectivity than any other product. That included paint, flat and gloss and several other products, including mylar. Have you ever tried aluminum foil? It may be worth a test.
I was thinking about mirrors, would they best? Cheers. Love the channel.💚🐛
I really enjoy your videos, as you are very informative in your testing. Thanks for sharing your test results.
Thanks Matt, I checked out your channel and subscribed. I'm going to watch your videos on hydro pepper production. I'm looking for advice on the best nutrient solution for our upcoming grow test with chili plants. Any advice on what to use for good flavor and yield?
Personally, I use Dyna-Gro Grow 7-9-5, which is a complete one-part macro/micro nutrient with pH stabilizer, and cal-mag. While I have not used them personally, the Masterblend, General Hydroponics, Maxi Grow, and other nutrients seem to do well too. Regarding flavor, a mature chili from a flavorful variety is a good start. Soil grown plants, when water stressed can produce some of the best flavors. For quicker results indoors, growing in rockwool blocks or small containers helps. Topping right after the 3rd or 4th leaf node helps to change the shape of the plant. You want a short and wide plant, with a good canopy. Also, trimming off the leaves under that massive canopy helps. Otherwise those under canopy leaves that are not getting light are just wasting the plants energy. In addition to small pots and effective shaping, using a wet/dry cycle with extended dry times will stress the roots without killing them. This is often another trigger to start the flowering and fruiting process. Don't be afraid of trying to switch peppers to flowering sooner than thought, as pepper plants will continue to increase in canopy size even after starting to fruit. Dryer air and more air circulation, combined with more interspacing between plants, helps push peppers toward fruiting too.
Thanks for the advice. I'll use that👍
Migro For the win
Panda film will always be my best friend!
Wish you tried mirrors and aluminum foil
Great video
Would reflective material be much help for the sides for the veg stage when plants are small?, as all my leaves receive light from above 2 x 600 watt MH for 18 plants grown a week apart on stands to keep the canopy even and to save space as well as having a continuous grow
I don't see how light on the edges of the leaves would help?
I harvest one plant per week
9 in flower, also if the light is powerful enough to penetrate the canopy, how does side reflective help, as there is none separating the plants in the middle of the tent
I have 18 vegging, for 18 weeks to get bigger plants and keep with the 9 week flowering cycle
9 week veg is not enough
I have a tent for the flowering stage, to separate the light cycle from the vegging plants that are in the same room it has
2 x 1,000 watt HPS
Thank you
I am not sure but if there are plants under the lamp most of the wall gets more or less black,good test would be with plants in the room like the real situation is.Only from eye it looks to me that white is the best.
You know those silver blankets that mountain climbers pack and that people wear after marathons / triathlons ? as a real budget build I am planning on using PVC pipes to make a frame then make the walls from cardboard wall papered with that silver blanket stuff , thoughts?
Great video. Have you tested any color variations in walls for reflective values? Blaze yellow, orange, green and blue. Materials like reflective signs, and tapes
Silly maybe
Very nice review. Really appreciate your methodical approach. What is the display unit you have plugged your apogee SQ-520 into?
WHAT? Youve been reading my mind shane... 5☆ mate.
Don't know if you'd have access to it, but I'd love to know where stucco aluminium sheet would stand amongst these. It's what the light shades are usually made out of
The mylar will reflect the color of the plants around causing absorbtion of the spectrum
Heres a question to see if u guys know your stuff lol, light showing through hole of a cabinet door frame, worst is the side, problem is i can put anything there to cover the gaps as the door needs the gap to open/lever…
What white paint do you recommend for better light reflection? Matte or glossy? I want to paint the walls in the corner of my room without a growtent.
i always wondered how a textured brushed aluminum contact paper would work. its really cheap
Hy,
Could you try with an high reflective white acrylic paint please.
doesnt the sensor have an intake angle? So it should actually be even more effective then the sensor is telling you. I would have liked to see the sensor being covered from the light source and be pointed torwards the reflective material.
Could you test regular aluminium foil with the same setup? :)
yes!!!
I was thinking the same thing for us people that like to DYI n make ok our setup as affordable as possible but at the same time when I do something I like to do it right the first time hence making it an ideal good set up but affordable as well with out having to make changes during your plants cycle which could in turn do more harm than good! Very curious about the aluminum foil readings and what you have to say about it! I've been told it's not as good as the other reflective material n that it has more of a chance burning your plants
Just use white paint or so its cheaper and reflects more
@@inkognito3145 That's what I wanted to know, is white paint more reflective than aluminum foil?
I just put up white poster paper that has a semigloss sheen to it so it works ok for me! I've never seen anybody put up foil n have heard it'll burn ur plants so that's why I didn't put any up but would still like to see what it reads n hear what it does.....!?!?
I have a problem, my grow area is 5’ by 20’ and not sure about the layout when yours are 5 lights to a ring. Should I buy two ring sets or just hang 6 x 400’s? Thanks, it’s a big purchase, any help will do and my canopy should be 4’ that way I can work?
Hi shane. What’s the difference btw 75um and 125um Mylar beside the measure? Is the 75 semi transparent or is it lightproof too? I already have matte white walls, no light leaks, should I buy the cheaper 75um one? Thx
The thicker one reflects more IR back so its better for ceilings of the room if you don't want to be the only house in the snowstorm with a clear roof. And its tougher/longer lasting, less rip/tear prone and if its backed with white, its cleanable. Thin mylar doesn't last, it goes see through over time becomes brittle and its noisy, thick stuff looks the same after 10 years
Where can you bye that mylar?
Testing revealed white paint be better than some reflectors being sold. The downside of most commercial reflective liners is that they are conductive and have killed people in their grow space.
I guess the white wash on a brick wall even helps.
Great info here. I'm surprised how much of a difference the reflective material makes. Would have been nice to try Orca as well. Thanks
We have an old video with orca tested against Mylar link here ruclips.net/video/XwTOlnZrUOE/видео.html
I used tin foil crinkled and works great and not expensive
And chance of an update video on some of the new HGL boards? Always found your videos to give fair comparison, I also own one
I agree. I'm also wondering about Hidden Harvests Growlight's 36 watter. It looks good but the low power kinda makes me wary
HLG? Like the 550 V2?
Hmm, ... Not sure where to buy Mylar or Diamond Mylar or Gro Tint. May I suggest, roll of aluminum foil ( dollar store), a backing material, (drywall?, particle board? whatever), plus a $5 can of spray adhesive. (Walmart, auto parts store, Home Depot) Frankly, I use the aluminum foil & I was hoping you would show how aluminum foil compares.
Yes I'm womdering why there's no aluminum foil in the test
Great video Shane. Am stil waiting for the Optic 1XL and Fluence Spydrx video :)
Do you make money doing this? You should, that's alot of work. Many thanks! Do you have a donation site?
can you do the same test, but using different tech? like HPS, MH, LED, CFL, etc? It would be very interesting to see the readings. To get the most light.
plain kitchen foil outperforms all these "special" materials...
@@samzi9669 reynolds wrap ftw
Hay Shane hope you enjoyed your vacation. Could you please touch base with me about your lights.
Sorry I'm late in replying. I'll answer your mail tomorrow. Take care Shane
How much does it multiply if you move the light up and add another wall on the other side?
best content about reflective materials !!!!! ty
Have you tested Tyvek house wrap?
I use a space blanket. 3 dollars. And your good to Go.
Hello... Hope your well, I've heard / seen the white mylar specifically sold as much better for LED. So is this just a sales gimmick?
Can you use high strength reflective tape?????
Matte paint is low on the reflective scale, just one level about flat, then you have semi-gloss, and then Gloss, I wish he would of tried Gloss White for this test, I bet it would of had much better results, probably on par .with the highest results.
gloss is worse than matte.
How about using thermal blanket or silver foils for food? Very cheaper
I wonder if the Lighthouse tent material be bought in bulk. In other words, do ya have to buy one of their tents to get the material.
Diamond silver Mylar is $5 a metre and just as good. Most silver Mylar tents are just as good. It's a generic and cheap material. In this case the cheap solution is best👍
is this video always good ?
Shane you need to do a new video comparison, mylar vs orca grow film. Orca claims to be far superior.
I absolutely enjoyed your demonstration very informative thanks 😄
Is it worth it to overpay for Mylar 600D? Because there is also Mylar 210D. For grow tent.
Hi,
Any diamond mylar is fine.
Thanks.
600D isn't the mylar, it's a thread count. Higher is always better. Mars tents are like 1650D and Gorrilla or AC Infinity are 2000D.
Do You have a Grow room using (Holographic reflective material) on the walls for Lighting If so Can You link the video or done.. I Was Think How Do Plant React to Rainbow Color Lightings
Hi there shane, here in holland i bougt a paint called thermoschield lumen its a paint special made for reflecting Light.
I did paint a closet with several layers for seedling for my vegatable comunity garden and indoor grow. Im testing
Cheap e27 led lights becousse my budget is low and the light is close to the plants.
I did not see the video yet but il just let u know maybe u know this option already.
Ps sry my typing language is bad 😂
But i dont know if its a good reflecting paint compairing to other options
Thanks I'll look at the lunenshield product. I think silver Mylar will be better though.
Shane its thermoschield lumen sry i typed it wrong
On the molar, could it be tacked to the walls like wallpaper to reduce or eliminate wrinkles?
i hope Migro does a review of the Torus Hydro PerfectpH, it sounds to good to be true and nobody has tested it on youtube!
Hi good man.... Please answer what w;l be happen 'f you paste mirror ?
We have a insulation product in Canada called silver board, it is kind of similar to those dimpled hammertone reflector liners imo, but I would be very curious to know how Efficient it would be as a reflective Material. I use it to insulate the inside walls of my grow area and it seems to help a lot... anyone please comment with any knowledge on this..
And as always , Migro gets down to the nitty gritty in record time 👍✌️👌
You can see what silverboard is by searching ( buy silverboard insulation Home Depot Canada)
Seems like a good alternative imo.
Thanks!
I've used that before with great results. Can't give you fancy metered out numbers but I can tell you from experience, it's deff worth the time. Just don't want the insulation dust to get cycled through your plants.
I use the foil coated bubble wrap. It's great. Seal the corners with the silver tape. Comes in 4' by various lengths and attached to 2x2 frames quite easily.
Cool stuff tnx! Take care 😊 peace ✌️ from Welland Ontario Canada 🇨🇦
Wouldnt those wrinkles affect the reflection/dispersion of light???
SHINY CLEANS BETTER WHEN USE PAINT IN MOIST ENV.
Good channel but hlg is a better light. Atleast from my veiw. My buddy got migro and my hlgs seem way brighter and get a better yeild. But migro still better than 90% of other liggts
Leds are way more efficient than hps these days
Thank you for this video, very interesting.
i want to know what happens if we use mirror as reflector
I think you should test the orca-sheeting again, but with an updated methodology to better simulate a real-life setup for growing.
The setup in which you tested the orca-sheeting in your prior videos seems severely biased against the orca-sheeting for several reasons.
I'm currently trying to figure out what kind of sheeting I should get, and it seems like the Lighthouse sheeting would be a good idea, but I'm not yet convinced that it beats the orca sheeting.
This is my reasoning:
1.) The orca-sheeting doesn't cover the entirety of the walls, neither vertically nor horizontally.
1.a) The gaps at the corners are bound to swallow a significant amount of photons.
1.b) The missing orca-film above the lighting fixture is bound to result in upward-reflected photons (reflected from the orca sheeting) being bounced almost exclusively towards the top. If there was a diffuse sheeting / diffuse scattering above the lighting fixture, many of the photons which initially get scattered upwards by the orca would subsequently be scattered back down again.
1.c) The open wall on one side (to take measurements) might also impact the results of the orca-sheeting more than non-diffuse materials. I don't know whether this is the case, but I don't think one should discount the possibility. It would also be possible to close the fourth wall for testing-purposes simply by using an elevated floor with holes at the locations of measurement.
A fair and thorough comparison of different sheeting-materials would require covering all of the walls and the ceiling equally, and without gaps (apart from tent-poles and the usual stuff inside a tent like vent-openings). IMO even the floor should in part be covered with the material in question, to most closely simulate a life-like environment, i.e. filled with plants but not overcrowded.
I will post this comment on your other (more recent) videos as well, because I don't know whether you'll see this here, and I really think you should take this into consideration in your comparisons. You try to be very thorough in your analyses, and I highly appreciate your content. But your reasoning why non-diffuse materials should be better seems severely flawed when considering a real-life environment, i.e. inside a space covered with reflective sheeting on at least 4 sides, most likely 5 or 6 (ceiling and floor).
this!!!
Very interesting I'm surprised quite how much of an increase there was. Go raibh maith agat mo chara.
Ta failte romhat
Have you tried using a standard wall mirrors would love to know
Never mind found info right after. Going with milar on a home build
what's about using traditional mirror ????
