Ona Gel can help massively with combating smells outside your grow room. Suitable for placing in ducting, the gel evaporates as it releases a neutralising odour - meaning it works until there is nothing left! Unlike Ona Blocks, this gel can be separated easily and distributed to where it's needed.
Available in three scents, Ona Gel comes in two sizes:
- 1L Tub ('Fresh Linen', 'Polar Crystal' & 'Pro')
- 4L Pails ('Pro')
