Grow Room reflection

no well my walls were not white before lol

my mylar wont fall i used a couple of cans of spray adhesive used for glueing down carpet tiles on the walls.. but as bricktop quite rightly said... its a mission to get it on the wall smoothly without wrinkles.. especially when dealing with a couple of meter lengths

ok,im saying I made my grow room comepltly flat white I have a 600 watt hps grow light just wondering how much this will help my yield

I tend to doubt that anyone could figure out a percentage of increase with each successive increase in quality of reflective material used that could be considered to be even half accurate unless it was put in a wide range for each with the added on statement of mileage may vary etc.
　
There will be conditional differences from grow room to grow room and then there are the genetic differences in different strains so it would be virtually impossible to tell someone that if they go from using reflective material ‘A’ to reflective material ‘B’ they will then see an ‘X%’ increase in yield. In different grow rooms with differing conditions and differing genetics the increase seen there might be ‘D%’ or ‘N%’.
　
Pick the best possible reflective material you can afford or that may for some reason work best in your situation, apply it/install it as perfectly as you possibly can and then with lighting and plant positioning try to make the very most of it and things will be what they will be.

That makes sence thank you
