Color to Paint Walls for Reflectivity?

[silentflyer]

Hi, I am finishing up a small room in my basement to use as a grow room.

Getting ready to hang some drywall, what would be a good color to paint
I was thinking flat white?

Will this be a poor reflector, would i be better with some commercial
mylar, etc.?

Thanks

Flat white is the best to paint it...

A friend of mine swears by eggshell.

I've often wondered this, why flat paint as opposed to a gloss?.

I always assumed(probably wrongly)that a semi-gloss would provide more reflection.

Self explanatory; a great option for large grow rooms or for people who are interested in a low maintenance wall. Flat white paint has the ability to reflect between 75-85% of the light, and does not create hotspots. Adding a fungicide is recommended when painting.

Glossy and eggshell whites do not reflect light as efficiently as flat white. Semi-gloss paint for example, only has the ability to reflect between 55-60% of the light. Also important to remember when using paint is that any smears or blemishes on the surface take away from how reflective the wall is so care should be taken to avoid marking or staining the walls. Titanium white paint is very reflective; however it is usually only used on reflectors due to its high cost.

there's a big list of materials and their corresponding reflectivity here https://www.rollitup.org/advanced-marijuana-cultivation/254752-flat-white-vs-gloss-white.html
