reflective paper

ok so just a quick question about adding reflectivity to my grow cupboard, i had an idea, and i wanted to know if it was maybe just a stupid idea or worth trying....

I have a lot of high gloss photo paper lying around in my house, most of which will never be used, if i put that all over the walls of my grow area would that be reflective enough for my plants? I know about paint and mylar, but I've spent a lot of time an money already, i would like to know if this could save me some of both since it's already here, i nevcer paid for it, and its easy to install, no mess no cleanups...any thoughts?

mylars only $4.00 dollars a square metre.

I've got photo paper avalible as well.

It'd be marginally better than white paint - but needs to be fixed and washed properly to prevent discoloration - esspecially when exposed to the extra lumens of a grow system.

Cheap mylar can be found in most stores with any sort of "outdoors" section, in the form of "emergency space blanket". Usually about a buck or 2. Works really well with a spray adhesive - you might have that around if you got lots of photo paper.
