I read this on the opening page. I have not done this nor seen any documentation on this.
Can the team elaborate In more detail please?
The Grobo unit will require very little maintenance; all you have to do is top off the water and replace the nutrients when the unit sends you a notification, as well as do a full system flush of the unit after every 3 grow cycles. This flush mode is fully automated and only requires you to pour a solution into the water reservoir as well as place the exterior hose in a bucket or sink.
