Grotek vs ONA - Please help!

Discussion in 'Growing Marijuana Indoors' started by Grasd, Aug 13, 2007.

  1. Hi,

    I have been looking for ONA, but cannot find any locally.

    There is a product from Grotek that is also an odor neutralizing agent, but I'm unfamilliar with it. A local store owner says it's the same thing. Apparently you get crystals, and a liquid that you use when the crystals dry out.

    Is this just as effective as ONA? (Looking to create a bucket/fan system as described in an earlier thread)

    Is it safe to breathe the air after it's been filtered through this stuff?

    Thanks in advance!!
