Gel for a fixed location
Want an odour neutraliser that releases continuously in one place? Gel is a practical format: open the jar and place it where you need supplementary odour control. Choose a separate location outside the immediate growing area and check the airflow around the jar.
For targeted use at a particular moment, explore odour neutralising sprays. Choose the format for the task as well as your preferred fragrance.
Extraction remains the foundation
Can you constantly smell air escaping from your grow tent? Check the air path, connections and filter first. Gel does not move air or regulate temperature or humidity.
A suitable grow tent carbon filter treats extracted air. Use gel as a supplement and address any persistent source of odour.
ONA Fresh Linen Gel: the 3 litre version
Our current gel range contains ONA Fresh Linen Gel 3 litre. This is the Fresh Linen fragrance in gel form, with a stated volume of 3 L. Check the product for current price and availability.
Open the jar and place it in position. Keep it stable and accessible for checks. Choose a location that needs supplementary odour control without directing fragranced air straight towards plants or harvested material.
A 3 litre volume does not define a fixed coverage in square metres. Odour load, air movement and the way you use the gel determine your needs. We can help you assess your situation.
