Is smooth mylar ok to use for grow room
Some people use mylar. Plain old flat white paint does a good job.
The smooth stuff can glare the light causing a hot spot on your plants, same reason mirrors are a bad idea
Agreed. Diamond pattern mylar is recommended because it creates even light distribution w/o hotspots.
That’s why I was asking, have a roll of smooth mylar, just didn’t know if I should use it or get diamond
I rolled out some heavy black construction visqueen. Sprayed with glue, rolled mylar on top and covered my tent frame. split the front and sewed a large zipper on it. Worked great!
Just want to be sure with it being smooth and not diamond print it wouldn’t burn my babies
