Which will reflect more light? (pics)

Just get some flat white paint its 85-93% reflective, aluminum foil is garbage and should be avoided it will created hot spots. Shit flat yellow paint has better reflective quality than foil lol
More "foil is garbage"... "hot spots"... It's like you're all quoting the same dumbass cuz it puts you in a comfort zone. That's whatcha call a "herd mentality".

Again.... anyone have any proof or is the circle jerk all you need?

Sorry buddy Arrid is correct... one of my friends tried it and it's horrible. Stop trying to defend yourself because you are only making yourself look like more of an idiot. Take it for what it is and move on.

For good reflectivity use mylar, panda film, titanium white paint or elastomeric paint.

i vote no on aluminum foil, i used it many years ago on my first grow and it was not good not good at all,,, unless your useing cfls/not enough light it wont burn em but it still is ment for cooking not reflecting light crappy cfl's yuk........ oh yea to the guy whos thread this is srry man but yea listen to the ppl that know and get the panda film or flat white paint, i used mylar and sprayed the wall with that spray adhisive crap you know the stuff

Your posts are like poison to this forum... Want proof? Go put foil up around your plants and lights.

Al foil is used for cooking. i put my chips on it and then in the oven. it reflects HEAT not light.

the heat will bounce off the foil and onto the plants which will make burn holes = not good.

just use panda film, its cheap enough :mrgreen:
Foil is an insulator... it's a good thing.

Aluminium foil - Wikipedia, the free encyclopedia
Aluminium foils thicker than 0.025 mm (0.001 in) are impermeable to oxygen and water. Foils thinner than this become slightly permeable due to minute pinholes caused by the production process.
Aluminium foil has a shiny side and a matte side. The shiny side is produced when the aluminium is rolled during the final pass. It is nearly impossible to produce rollers with a gap fine enough to cope with the foil gauge, therefore, for the final pass, two sheets are rolled at the same time, doubling the thickness of the gauge at entry to the rollers. When the sheets are later separated, the inside surface is dull, and the outside surface is shiny. This difference in the finish has led to the perception that favouring a side has an effect when cooking. While many believe that the shiny side's reflective properties keep heat out when wrapped on the exterior and keep heat in when facing exterior, the actual difference is imperceptible without instrumentation [6]. The reflectivity of bright aluminium foil is 88% while dull embossed foil is about 80% [3].

Oh Shit, forgive us. I thought we was talking about the reflective properties with foil vs something that actually reflects 99% of high dollar lighting & elect. bills. A Rag off a Terrorist would insulate what?, bad temp? Do you people want to muddy the simple question more?, Muddy the Waters? Here's the ignorant-ass question. When Bud Worms eat foil, is that the cause for Global Warming? Mylar relects 99%, find a better stat, or do the bake potato method. Good Luck.

It's for cooking, now shut the hell up. :dunce:

You are wrong there mate...
Mylar = 90-95% reflective..

You're dumb Arrid. If you've had a bad experience with aluminum foil then speak up. Otherwise you're regurgitating what you've been told. But..... I have used aluminum foil and your whining doesn't do shit for me.
Using aluminum foil reflects the heat back at the plants more than the light and makes little burnt spots. This HAS happened to me before, who give a good damn if you got lucky, unless something always works good dont suggest it.

So no one really answered his question, and I am somewhat curious also, can Reflectix be used or will it have the same "burning" effect as foil?

We've already discussed insulation as a property of aluminum foil. Don't blame something else for your mistakes.

do you seriously think tinfoil is good? looking back at you quoting wikipeida the first line it said something like .25MM thick wich means it cant hold heat at all and reflects it back (along with the light - ps it doesnt reflect alot of light it sucks.)
because of this it makes HOT SPOTS we are all talking from personal experience your obviously not go learn something please, you no like read a book?

not wikipedia anything from there can BE EDITED!

Foil is flat... it is no more convex than mylar or a reflector. As for the Wiki stats... they are referenced and quoted. Webber your statement is neither here nor there. Read the Wiki article again and you might learn something. Thing is..... you have to pay attention. Anything on this site can be edited.

I know a lot of you have to worry about just keeping your plants alive so I'm not mad at ya for thinking you can't do it. All y'all need is an open mind and a lil experience. Keep it green.
