i've heard about it. didn't pay much attention to it though. realized for it to work, I would always be putting on a coat of paint and that is just not practical.
i have found a new paint everyone should try if your making A indoor grow room. It is called kilz oderless white paint. it is highly reflective and kills oders from inside the room....please hit me up if you decide to try this...
warm if you had a pet and let it piss on the same spot where you put the paint, it would eventually begin to smell again.
