Is there an instruction on how to replace the pH sensor?
((# GroboFixMe )):
(Instructions to dismantling the Grobo under ‘Hide’): (Other than that Follow the PHsensor cord):
Thanks, Barbara! I don’t need to replace it just now but by the time my third grow starts, it will be due for it’s yearly replacement
Great question @coffindancer!
@Stephen May I suggest that this and other procedure’s be located in a sticky somewhere on this forum?
