GHL SA2 (stand alone).....set to auto (automatically alternates dosing time so the doses never overlap)....25 ml of both Calcium and DKH (Randy's recipe, #2 recipe for DKH)24 times/day.... manually dose Mg...... system is roughly 150g....considering adding a third pump to it to dose phyto
I couldnt be happier with this set up.....very easy to use and set up...
