Ona Block is a semi-solid odor neutralizing agent that slowly releases to eliminate any airborne smells. Made from a complex formula, it uses essential oil technology to destroy a wide spectrum of organic and non-organic odors. Not a masking agent; it neutralizes odor.
Ona blocks work well for small amounts. Invest in a carbon air scrubber or make one yourself. A negative ion machine will cleane the air but you may notise that your finished bud smell less stinky.
