If you have a living situation where you cannot have any scent escape the unit, please be advised that the Grobo is not 100% scent free. 

Smell is often a concern when growing cannabis. That is why Grobo's smell reducing Carbon Filter is here to help! Our custom filter uses two layers of activated carbon to help filter the air before it leaves your Grobo. The smell becomes strongest towards the end of each grow, and pungency can also differ between different types of strains (i.e. some are smellier than others). 

We recommend changing your filters after each grow and keeping your Grobo's door closed as often as you can for the best results. You can purchase Carbon Filters on our store, HERE
