Is there a pH controller?

[turtle420]

this is how it works, stick your head in the 5- 10 gallon tub for 15 mins. blink 3 times while biting on 4 roots, if you come up out of the water after the full 15 mins with the roots still in your mouth---ph down

LOL!!!!

Yes, those machines come... they're called "Dosers".
