How to use Ona Blocks

ONA Blocks are a fast and easy way to fight against odours at their source. Simply open and expose to the air or remove the block from its container. The duration of the block will vary but it will be effective for about 4 weeks relative to the airflow and environment around the block. To limit the amount of odour control and extend the life of the block, pop on the floral pattern lid, making it excellent for hydroponic setups.
