Support is not available so I guess I"ll try here. After a very disappointing harvest (only 17 grams of mostly small buds) I have now cleaned the unit as per the Grobo instructions. But now I’m trying to fill it back up, the app is telling me it’s at ‘optimum’ level even though the unit is empty. I went to Drain, then after a few seconds it said it was done and asked me if I wanted to Fill. So I did and the app is still telling me it’s at optimum level.
Given these problems and the pitiful yield I got, I’m beginning to lose faith.
