With a variety of different scents including Fresh Linen, Polar Crystal, Apple Crumble, and the simple PRO formula, ONA Block can help to ease the odor concerns of any indoor grower while adding a fresh and appealing aroma.
To activate the blocks for grow room or grow tent odor control, simply open and poke a few holes through the protective seal, or open fully depending on personal requirements. When deployed correctly, one six ounce ONA Block can effectively neutralize odors from a 3×3 grow tent.
