Brand differentiators for odour control
Within the neutralisation category, brands offer distinct approaches. Zerum provides a wide spectrum of gel, spray, and block formats with various scent profiles catering to both automotive and general space use, suitable for budget-conscious growers and professional applications. ONA focuses on natural essential oils and advanced technology for persistent odour elimination, offering powerful solutions for dedicated grow environments and general household use, appealing to those prioritizing natural formulations. Sure Air specialises in gel-based systems with long-lasting aromas and mechanical dispersal enhancers, ideal for continuous odour management and integration with larger containers.
Your path to a neutral grow environment
For growers dealing with moderate odours in enclosed spaces, starting with a gel format like Zerum PRO Gel Neutral, 900 g or Zerum PRO Gel Lesní jahoda, 900 g is recommended, particularly for soil or coco mediums. If ventilation systems are in place, integrating ONA Odour Control Duct 200 mm with ONA Block Fruit Fusion 170 g offers a targeted approach. For persistent or intense smells, especially those from smoking or animals, consider Puroder likvidátor pachu HEMP 100 ml for its ability to penetrate porous materials. Those requiring a powerful, broad-spectrum solution for larger grow tents may opt for Vaportek Maxi do 20 m3, while ONA Liquid PRO 20 l is a robust choice for extensive odour control in professional settings.
