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 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.

Thanks potroast that sounds pretty good to me if that is the case, I was a
bit concerned it may cause possible hot spots, do you think there is a
chance of this or not?
While I have your attention I have a query on a ball shaped growth noticed
on 1 of my babies today, you seem quite knowledgable as I have read a
number of your posts in the past, can you give me any insight to whether this is a pre-flowre or not please
Any other thoughts/suggestions from anybody is welcomed

I don't think that you will get hot spots, because the surface is smooth.
That appears to be a preflower, and it appears to be a male preflower. It's hard to tell, though, and you should grow it out, and induce flowering to be certain.
The triplex-node trait is nice, I've seen it once, and if it's a female, she will have a nice yield.
That leaf-edge curling you have is probably from too hot or too dry.

Yeah Roast if the curling is due to to hot or dry then you would be right mate, humidity is only 15-30%, I have 2 towels in there hanging up which dry out twice a day. I water the towels in the morning and before I go to bed, dry each time. The humidity must get sucked straight out as it evapourated off the towels. The temps get to 37 (100) max temp with a min of 20 (55) daily, can't help it with this HPS light in there. I suck air from my sub floor which is always cold... fucks me what to do

Polished metal (85-95%) has about the same reflectance as mylar (92%) without the hot spot problem found with mirrors and the shiny side of aluminum foil. But as someone else mentioned this is rarely brought up because of the cost associated with polished metal. But since your cost is free! no worries!

most definetly! I went to the dollar sto' and got 2 packs with 6 sheets for 2 dollars. Switched that out with my tin foil that I was using, and noticed a HUGE difference immediatly. It was all of a sudden daylight in my grow space ^_^

This is good to hear, thanks 468 & Sky, it appears to look dull though... not bright like say white plastic or paint, it is very highly polished though not bright like I would expect
