i cover the walls of my cabinette with aluminium folio. but at the back side i put a big mirror. other sides are covered with folio.

so my question is;

what is the best wall reflector material?

white painted wall?
aluminium folio?
or mirror?

foil = bad

mirror = bad

white paint is good, but you want to go out and get some mylar

Well you clearly haven't read up on your little project before you just jumped in... If you did, you'd know that foil and mirrors are the two absolute worst things to have.

Flat white paint, or mylar is best.

Good luck.

aluminum foil is a big no no.. it causes too many hot spots and will cause burn to your plants.. i think i have read that semi gloss white is like 80% reflective, and that flat is like 85%.... mirrors do not reflect light at all, but rather absorb light, so that is another bad thing to use... they make specialy made foil(mylar) for grow rooms that is like 95% reflective and only costs like $20 or so for a decent sized roll... either that, or just go with the white paint.. i have flat white walls, and they seem to work great..
whichever way you go, best of luck on your grow..

i just searched for mylar on the internet. and it looks similar to alu.foil. but yea it is a special material for growing plants.
and what type of mylar would you prefer?
diamond or normal?

also where do you buy it from? except for internet!
a shop for fire extinguisher and materials ? :)

and what type of white wall dye would be the best?
oil paint? or doesnt matter?

also whould it be ok if i used some big cardboard and paint them to white?

except for mylar or flat white latex, does oil paint work fine? and if so what is the reflection ratio of oil paint?

Click to expand...

once u paint it with oil base paint ur always have to use oil based paint, get something thats easy to clean up with water based products... ive seen primer work just fine but i would go with flat white... 15-20 bucks for a gal or flat white spray paint since its for a cabinet i think u said... that would be 5 bucks...

Paint the walls white, or buy this mylar... http://www.plantitearth.com/grow-lights/mylar.aspx

Mylar is almost 100% reflective that wont "crinkle" and make sharp points of light, like tin foil. It's suggested by every grower that knows what it is.

{Edit} I wanted to add that it seems as tho your taking advice very well, and not being objective at all. You should change your name to "Learns well".
