!!!!!stop using tin-foil for god sakes!!!!

Why does there always have to be someone that goes above and beyond for a stupid reason? The argument here is the foil is useless for reflecting of light in a growing environment. And its true. Flat white paint is much better and more evenly distributed.

Agreed. All this thread was meant to do was inform people that before you spend HOURS OR DAYS covering your entire grow in foil,not to. The cost of the foil and time you spend isnt worth it. If i didnt see 10 different people on here with foil from ceiling to floor i wouldnt of made this thread. This is a source of information pertaining to the the cultivation of legal, medical marijuana grows last time i checked. Ive seen pictures of your grows before and information you post, always accurate and great looking plants. Good to know someone out there with reputable experience gets the point of this.

Let me see...so much "parroting" of useless info... Question for OP.... you say 'Tin Foil' holds in your heat... because of your chicken nuggets experiment ... Too Funny.... So, in a cellar with an ambient temp in the winter time of 46 f degrees.... If I used 'Tin Foil' [I prefer Aluminum foil] to cover my walls, it would hole in some of the winter warmth from the lights so it Would be warmer ?? Wow, that's a great Idea for tin foil... keeping your room warmer in the winter.... I might want to use it, for sure...

Actually the chicken nugz reference was used to dumb down the thought process so people like yourself can understand what TIN foil is made and used for, and thats cooking, not growing.

I'm guessing ya'll talking about aluminum foil...

Cause most people here grow epeen instead of cannabis. They derive self-esteem from their 'grow-knowledge'. It's hard for them to admit they were wrong about something they were so certain of....

You're wrong by the way. I could show a fairly decent and unbiased test busting the oldskool 'white walls myth', it shows aluminum foil, radiator foil (normally used to keep heat from heating inside...) and mirrors and others reflecting nearly twice as much light as white walls (also the ol' chalk and thick layers etc). Regular mirrors aren't great because they absorb more than just visible light, but it (in that test) still beats white walls - by far.

Distribution... ever wondered why reflector hoods are alu and not white? The ideal situation is to have a stroke of mirroring aluminum(-like) material that works as an extension to the reflector hood so you aim most of the light at the plants. White is better for lighting up the space yes, but you want to point the light towards your plants and not distribute it randomly. Indoor=controlling the environment of the plant.

The test, the pics, the numbers, and results even under T5, etc, or a cool pic of NASA growing with alu mirrors on the wall (and they hate wasting energy in space) I could grab them in minutes, but since you claim white is the way to go, show me your proof, and I will show you mine.

Blue pill is for white walls myth, red pill is for the truth. Take your pick.

mirrored aluminum and mirrors are two completely different things, i was talking about mirrors being inefficient. Dimpled mirrored aluminum is the most reflective stuff out there so of course nasa will use it. Normally used for reflectors, it is now being used for grow rooms. It's all about % lost when it comes to reflective materials, and i agree with OP that the tin foil is the worst stuff out there, use flat white paint on a flat wall , tin foil causes heat spots (potential fire) and also, you get less reflective %. Mylar is sold at wal-mart as "emergency blanket" in the hunting section, try the shiny side out.

stop the aluminum foil BS and understand lighting people who disagree

I use aluminum foil in my grows.....just thought I would point out that wrapping chicky nuggies in foil stops air flow from dissapating heat, aluminum is actually quite effective at this which is why you have to use hot pads to take a pan out the oven but you can pick the foil and your cookies off the pan with your bare hands. Also why on cars they make things out of aluminum things to be cooled like your intake, heat shields, and cylinder head/block but that's also for weight reasons.... aluminum foil is an effective way to reflect light on the cheap..it reflects better than white walls....look it up....ugh people make threads like they know everything..but its the internet if you want an actual answer this isn't the place in my opinion

Aluminum foil , fuck just about every new grower tries this trick as runs with it . Surely we all know that it is not worth the time and effort but none the less let them wrap and tape all they like . In the end we do not have to hear this ANOYANCE or deal with it .. I just ignore it like I do Miracle Grow and all the rest of the silly beginner shit .. Note that most who do use foil only do so for a short term , as nine out of ten times the foil never lasts beyond the first grow if not wrecked during .. Peace ......PotSnob

I have used Aluminum foil, so please pot gawds forgive me my sins.... Just don't blame the 'tin' foil for all your problems... Seems to me, those that take responsibility for their actions, do not have a problem with Aluminum foil... Hummmmmm those that have problems, want to "BLAME" someone [My Brother was supposed to water my plants and now they are dead... must be the tin foil] or something like: "I can't figure out whats wrong" Threads and he's growing in MG soil with tin on his walls... so it's always someone/something else fault... Take responsibility for your own failures in growing, and stop blaming MG / Tin Foil / CFL's / for your problems... It's you.... Sorry, once you figure it out... You'll understand.... once you get it, you'll get it... until then... it's fun ...just watching you!

Not endorsing specific products but this pretty much explains my views...

400w flouro, MG Nutes , mirrors and garden dirt.
They are about 16-18 in tall

"Spiegel" means mirror. Witte/wit is white. From a test with a setup created specifically for testing, no direct light to sensor, only reflection. Not the best and most reliable test, but a fair unbiased one nonetheless. A common mistake also mentioned in the original (dutch) thread is people applying photographer knowledge to growing plants. (Or worse, use mythbusters Mummy movie myth as example...). As I mentioned in my previous post, diffusing the light is not a goal in growing, lighting up your grow room neither. Directing all the light you got towards the plant is, that's the logical way to go. Hot spots is BS (also tested, including using IR cams...).

From the guy after which we named the Torsti plates (sort plastic plates with a reflective alu layer, easy to clean, will last a while...) in the list above. That's a 0.92GPW grow, notice the lights above it.... You don't want me to start posting pics with buds...

And for the people who want to insist white walls work better, why do you think the best grow tents aren't white on the inside... Can you really fool yourself they haven't tested it extensively? Black and white foil used to be popular here... it's now the cheap stuff because everyone knows there are much more effective options. The point is to reflect the light the plants want and use, not make the room bright.

I agree with this logic when it comes to your hood, you want the light directed/focused down onto your plants...

How many grow tents have reflective walls that aren't textured or pebbled? Once the hood has directed the light in the direction it is aimed, all the light that missed the plants needs to be redirected to the plant. A flat reflective surface will only reflect light in one direction in relation to your light source but a textured/pebbled reflective surface will reflect the light on many directions with more likelihood of hitting the directed target (the leaves).

Watch the video with the laser pen i posted on the previous page, if that doesn't provide you an understanding of what i am saying we can agree to disagree.

so is that a reflection from your mirror?? lmao nice looking tree's. wait mirrors don't reflect.. just fyi mylar is used to make mirrors so why would adding glass make it non reflective????????

Mirrors are reflective.... just not useful. If you look at your grow light in a mirror, u see an image of a light bulb perfectly reflected plain as day. This is a lot different than dissapating that light over an entire surface area and reflecting it.

Glass Mirror are electro plated.
The best NASA polished metal ones are about 99% reflective ,but the cost is prohibitive. Hubble telescope expensive.
Common glass is almost as good exept you lose some to refraction an tint. About 90-95% reflectivity.
It owns standard hvac polished metal.
Most can't cut glass or get it free, so its not for everyone.
But its free side lighting for me...


And remember mirrors only work when the angle if incidence is correct....
Flash your plants , they like light.

i said flat white painted walls would be better tan tin foil. Isn't the layer of glass in the mirror what filters out the light ? Why not just use a mylar film or something if it's the same as a mirror? I understand that a mirror is good, but I think plain old cheap mylar is much better. As far as a light reflector goes why not dimpled aluminum??
just wondering , and not saying that mirrors will grow crap weed, that plant looks great, I have already gotten deep into this subject before and came to the conclusion that mirrors are to be avoided, so i gather you're saying check the angle of the mirrors and make sure the reflectiveness is pointing right at the plant?
