ONA Gel Polar Crystal 20 Kg. is an industrial-format odor neutralizer that releases a clean and crystalline aroma through slow evaporation. Bucket designed for large areas in indoor cultivation, shops, and warehouses, with prolonged coverage and easy handling.

ONA Gel Polar Crystal 20 Kg. belongs to the professional range of ONA odor control. The gel matrix integrates essential oils and active agents capable of capturing and neutralizing odor molecules in the air, instead of masking them.
The Polar Crystal profile is reminiscent of freshly washed clothes and mountain air, ideal when discretion and environmental comfort are a priority.
The large 20 kg volume offers extended autonomy in grow rooms, work lines, and logistics spaces. Simply open the container or distribute portions in ventilated containers to increase the exposed surface and promote diffusion.
Technology designed for demanding environments —treatment plants, factories, facilities with animals— and successfully adopted in homes, businesses, and indoor grow cabinets.
Compatible with assisted diffusion through ventilation or fan dispenser to increase reach (higher consumption when airflow increases).
Suitable for coexistence with plants, people, and pets; effective against cannabis, tobacco, kitchen, humidity, and animal odors.
Available at Hydroponics Blanes, Grow Shop in Spain with expert advice, catalog of cannabis growing accessories and discreet shipping from a true trusted Grow Shop.
Phases such as flowering, trimming, and drying significantly increase the odor load in Indoor growing. The ONA Gel Polar Crystal 20 Kg. format keeps the environment controlled thanks to sustained release. Ideal for technical rooms, workrooms, curing areas, and extraction corridors, where a fresh, light, and constant aroma is desirable.
It is used to neutralize persistent odors in large areas: indoor crops, warehouses, public spaces, bathrooms, and industrial kitchens. The gel formulation bonds to volatile compounds responsible for bad odors and deactivates them, leaving clean air with a Polar Crystal identity.
Considered a high-performance cannabis growing accessory, the 20 kg bucket reduces refills and simplifies aromatic logistics. Direct integration in indoor grow cabinets, drying chambers, and trimming areas, as well as auxiliary areas where it is advisable to maintain a pleasant environment for staff and visitors.
Recommended during odor peaks (advanced flowering, harvest, and drying), on days of high humidity, in rooms with limited ventilation, or during periods of intense activity. Suitable for large homes, shops, and warehouses needing continuous neutralization and a fresh, non-invasive aroma.
1) Open the bucket and gently stir the top layer to activate the surface. 2) Remove the necessary amount and distribute in ventilated containers to maximize the contact area with the air. 3) Place near returns, entrances, or emission sources to improve circulation. 4) For intensive diffusion, use a fan dispenser or integrate into ducts with a coupling (greater reach means faster consumption). 5) Replenish portions when intensity decreases. 6) Store in a cool place, away from heat and sunlight. 7) Avoid direct application on plants or sensitive surfaces; prevent contact with eyes and skin; follow the manufacturer's instructions.
