No, you cannot put a humidifier or dehumidifier inside your Grobo grow box.


This is because it can harm the delicate technology inside and will void your warranty (Click HERE, read line four under 'Warranty Exclusions'). In some cases, it can cause irreparable damage to your unit that will not be covered by warranty if identified by Grobo Support. For an example, click HERE


If you want to change the humidity of the room your unit is located in, use these appliances at a minimum of 10 feet away from the unit.
