Odors are one of the biggest challenges in indoor growing. In a grow tent, intense odors quickly build up from plants, fertilizer, irrigation and drying, and can escape to the outside. With SmellCrusher you have a professional solution at hand that reliably neutralizes odors instead of just masking them. Whether Absorber Gel, 40 Day Gel, Absorber Spray, Fabric Freshener or Car Freshener – the products are versatile and offer discreet, long-lasting freshness.
SmellCrusher is a brand that specialises in odour neutralisers rather than masking scents. Its range covers gels for continuous use, such as the 1-litre Gel in Breeze, Bubblegum, Fabric Fresh, Lemon and Orange (Orange also in 5 litres) and the compact 40 Day Gel, plus the odourless SmellCrusher Absorb, the Fabric Refresher for textiles, a Perfume spray and a Car Freshener. Pick a 1 L gel for a grow room, the 40 Day Gel for a cupboard or small space, and a spray for quick use. Keep gel containers out of direct airflow so they last longer. Find the full category in air fresheners, pair it with carbon filters and see all pest & odour control.
