it hasn't been discussed a lot. Most of us couldn't afford to put stainless on our walls. If we could we would buy better lights first and just slap some flat white paint on the walls. VV

i dont think it would really help that much i mean u can just get tin foil and face the dull side out..ghetto but efficient

Or just use a roll of mylar....cheaper and a lot more effective.

The stainless cost me nothing, my mate had 3 or 4 sheets of

2700x900x18mm thick MDF with 2 mm highly polished s/steel stuck to it, left

over from a commercial building job or wrong size... I built the whole room out

of it

Here's a pic of whole room

you should lower that light a way more.

that's just an old pic to demonstrate the walls made of stainless steel, the HID is currently approx 2 foot above plants, they were/are still young, didn't wanna suck the life out of them

That looks like the evil supercomputer from Superman 3!

Here's a good time to repeat this:

Here's the chart of percentages of light reflected from Jorge's latest:

Foylon 94-95
Reflective Mylar 90-95
Flat white paint 85-93
Semi-gloss white 75-80
Flat yellow 70-80
Aluminum Foil 70-75
Black < 10


They say mirrors are not good reflectors because the light must pass through the glass, and that diminishes the reflection. But since you have a mirror-like finish without the glass, it might be up there around 90 percent.
