mirrors

[detroitfish]

does any one have a grow room that has mirrors on the wall to reflect light?

if they do, they're silly. mirrors absorb more light than they reflect.

yep, you're right. mirrors are a bad idea. they only reflect light back to one point. and they abosorb alot of it too.

They can also create hotspots.... I use white poster board.

light-wise, a mirror is like a 'black hole', no good ... go with flat-white surfaces :thumbsup:
