???? WTF ????

Ok, does "feed meter" stand for pH/EC/TDS/ppm meter?

Important? Well...
Short answer: yes.
Long answer: yes.

But, if you've been successfull without one... well, keep it up... unless, you want to improve your grows... or you want to know what happened when something goes wrong... or if you want to push your plants to the limit... They ain't that costly...

Peace and love GrowMan,
