is white paint REALLY better at reflecting light than foil? i just don't see how... but i know foil causes "hot spots" but does the paint actually reflect more? would any of you guys use white paint in a GR if you didn't have the money for mylar? thanks
cheers,
sd

My GR is painted Matt White mate - you'd be surprised how bright it is when ya open that door

Upgrading to Mylar soon though, cos that stuff really is ---->

hi skinny d,
if i didn't have mylar i'd use white paint,definetly.......

most of the growbooks say the same aswell i think...

hi guys,my new growbox is still on the drawing board,sitting relaxed hi ,? is mylar self adhesive,like fablon!! or do you have to provide a paste,also would it adhere to new plywood thanks guys regards twinkle

If you can't run to the expense of Mylar then I would suggest rolls polystyrene wall insulation. You'll get it in any wallpaper shop or DIY store. It costs about £2.50 -£3 a roll.

I looks dull but according to the stats it's the next best thing to Mylar in terms of reflective properties, far better than paint or foil. I used it until very recently and haven't noticed any drastic improvement since changing to Mylar.

nah they are not self-adhesive...........

i used a stapel gun(i was in a rush,

but this isn't good enough,as it gets pulled about,

i'm gonna re-do mine,so i'd be interested what others say...

i was gonna spread silicone on the wall......is there a better way??????

Twinkle = Use a staple-gun it's quicker and easier.

Sorry about that sr, you beat me to the post. Good to see you can spell better than me as well.

Stapel gun worked for me, it's still on the wall.

cheersguys,looks like the staple gun is going to be ressurected,does the shop sell mylar,regards twinkle

there has to be a better way?????? or am i just heavy handed?????

i just sprayed my walls with glossy white spray paint and its WAY brighter than the foil i was using!

try not to use a glossy paint...dull paints reflect better for some reason.

Hi folks,

Got this from a book;

Reflective Qualities.

Foylon 94-95%
Mylar 90-95%
Matt white paint 85-93%
Vinyl silk white paint 75-80%
Matt yellow paint 70-80%
Tinfoil 70-75%

Hope this helps.

thx payday... i have cardboard walls and i covered them with 2 cans of spray paint.. it is semi-gloss white enamel and the difference between the foil is very noticeable.
