Aluminum foil in grow room. bad or good?

[fluffy100xr]

Aluminum foil is one of the worst reflectors you can use, go with white paint.

Here is a logical Statement...

White, is white because it reflects every color when light hits it.

but a reflective surface only reflects the same color that is shown to it.

hmm.. imo its an each to their own kinda thing.

I used to run black gardening plastic around the walls, then foil over the top.

The black plastic used is the type that people put down in their garden beds before putting mulch or bark or anything else around their plants. Cover the walls in this & then foil was put over the top.

We only used the plastic to keep the privacy of what we were doing.

i suppose the logical thing to use is a thermal blanket, those big foil things they use after running a marathon. they're designed to reflect light and heat. 80% light is reflected off them so i guess they're the best things you can get, and they're cheap too.

aluminum foil can be really good depending on how u use it. white paint is better, mirrors are no good because they absorb to much light (trust me) and dont disperse it evenly. mylar is overated.. doesnt do much more then white paint. the reason foil gets bad is because it wrinkles to much and doesnt reflect as nice.

My walls are already white, muuuhahahahahha

white will reflect around 90% of light. mylar will reflect around 95%. crisp paskets are a cheap source of mylar if you use a bit of elbow grease. alluminium foil is a poor reflector.

It's also a bad for you. Yet most people apply aluminum to there blood stream on a daily basis. Often even more than that.
