I have been using a tio2 spray in my grow room and in the room that the grow rooms are in for a year now. As a result I have found that the plants grow a little slow in the grow room and it grows out more than up. In the budding room the buds don't have smell.`I have also had no mold problems at all. I think that this is the next way to rid your garden of smells and mold! Your should try it out.
