All the hardware is finally in, and most everything is set up. A couple of disappointments, however. First, one of the ph controllers is defective (see the pH readout in pic!). Second, I simply had too much stuff to squeeze into these little cabinets, so the co2 cylinders have to sit besides the cabinet, which puts a damper on achieving a 'clean' look.
Once I sort out the pH controller issue, on to plants!
