I have white plastic from grow store this Post makes me kinda want to change it. But I wonder If White plastic is better than white paint. But Mylar still seems to be the ultimate best.

The difference between mylar and flat white paint is very minor. And mylar is much harder to work with and keep flat against the walls. On the other hand, some surfaces (smooth laminates) aren't always easy to get white paint to adhere to, so I did use mylar in my big cabinet. When I can, I use flat white paint. When I can't, I use mylar.

Right now I have the white and Black plastic that you find at your grow shops. Plus painting would stink to much in my Apartment. After reading that post by, Can't rember name I was thinking of switching to Mylar. Because I am in such limited space and everything helps. But I guess if the difference isn't much? From mylar and White Grow shop p[lastic. Ill just stay with what I've got
thanks

i use aluminum foil tape from hope depot

you would probably be doing your plants a favor, to switch to white walls ... regular foil (IF that tape is similar to aluminum foil) ABSORBS light, not good at all for a reflective growing surface ... :smokin:

No no, no mirrors. Not good.

Best is mylar.

After that is flat white washable paint with fungicide.

Yay, fungicide. Boo, fungus.

[MegaOctane12]

Stinky is on the ball......... as usual.



I would say that the white plastic material is just as good a substitute for white paint. It really depends on your situation. Mylar is best, flat panel white or white plastic sheeting come a close second, the loss in lumens is neglegible.

But why no mirrors? They reflect 99% of light.

Hotspots.

[Skeebo]

Reflection of visible light is completely different that PAR. Reflected light from mirriors may have modified the light photon, thus changing the level of the energy and loosing some of the energy,

black and white poly is cheap and reflects 90% of light

As far as paint goes, you got semi gloss, enamels, mylar, latex, spray paint, satins. But where are you going to get the ingeredients for the paint from. Barney the dinosaur??????? Maybe you should just use wallpaper.

aluminum foil can be used, but u cant use the shiny side, u must use the lesser reflective side, like with using mirrors, useing too reflective of material can cause hot spots on the plant and burn it causeing more harm then good.

[stinkyattic]

Tinfoil is a waste of time. Really.

[harris7]

I use the white/black plastic. and i would have thought it to be a lot better than white paint. With the plastic it reflects images (like a mirror) at certain angles and is really glossy, seems way better than paint. As well it is very strong and can you can easily change it around

:D :D cant believe i am going to try to give adivce :D :D

I used this stuff called reflectix (i think thats what it is called) it is like bubble-wrap but covered in thick foil (some of it you can even pop !! :D :D)) anyway and from what i know it is really cheap and is nearly as effective as mylar, shoudl be able to get it in any DIY (home work) shop under insulation because it is a really good thing to keep things inuslated.. :S hope i helpe :D :D :D

1: Take a piece of thin wood painted flat white, and photocopy it. Copies Result: White
2: Take a peice of mirror, and photocopy it. Copies Result: Black
3: Take a piece of melamine/mica, and photocopy it. Copies Result: White with sparse spots of black.
4: Take a peice of tinfoil, and photocopy it. Copies Result: Mostly Black and many white spots

Conclusion: Mirrors suck.
:thumbsup:

[halosin8r]

I have no Mylar at hand so I cant test it to see its reflectivity through the simplistic science experiment of PHOTOCOPY. If some one has a peice and a scanner, please do so and let me know ;)

I just go to the dollar store during the christmas excuse me the holiday season and by the super shiny wrapping paper. The non decorated side s just as good as mylar but nowhere near as expensive. If u like me and keep leftover wrapping paper u can try that. If not just wait another month and a half and buy some from thte dollar store.

Hope it helps

[youngcity]

Though its not as easy to work with as mylar because its so thin!

[stinkyattic]

Hey if you wan tto be really cheap just go to a camping store and buy some emergency blankets for $2 each.
They're thin mylar.
Hang them FLAT.

[m.g.]

mylar is the best reflective surface but is a bitch to install and even more of a bitch to keep clean. it also can cause mold to grow between it and the wall from lack of circulating air. and unless it's kept clean it's no better than flat white painted walls, which are next best and most often used by growers for its easy application and ease with cleaning. aluminum foil might look good to newer growers but is actually a waste of foil and time as it soaks up needed spectrum and creates hot-spots. mirrors are the absolute worst to use...the reflect very little beyond 'white light'.

just stick with 'the book' and you'll have a harvest worthy of your time and effort.

i use the shiny side of tinfoil, i have no hotspots, works great

[partcleguy]

I use foylon (or alumaglo?) in my cabinet. It works great! It looks like duct tape in that it has all those little strings that reinforce the material in the middle, with a shiny reflective side and a non-reflective side. It reflects about the same as mylar and it has much better light dispersion than mylar. Only problem is it might be a little expensive (which isn't a problem in a small cabinet- don't need much) :thumbsup:

man you cant tell if you have hot spots. only the plants know.

does this mean you can talk to plants. :rasta:

[stinkyattic]

You may think so but other things would work BETTER than 'great'.

[Pass That Shit]

You can go back and forth of which one works better and more effective, but here's what I did. Decent size room. I picked up a gallon of the cheapest flat white at the box store and just slapped it all over the walls. I did stink up the joint, but I did the room in two shots while I shifted away the plants. It was easy, fast and cheap. Peace

[Pass That Shit]

Also, I agree about the mirrors. I don't think the 99% reflective stat is the problem cause that's a good thing. I feel that the mirror advances the light making it way too powerful for the leaves to consume nutrients from it. It would be like taking a plant and moving closer to the sun. You'll just fry it.
