Im going to be putting together a new grow box/room soon and I really like the idea of a fully automated pH controller. Something with a digitial box I set my desired level at, has a sensor that goes into the resevoir and two individual pumps one for ph up and one for ph down. The controller will turn on the needed pump automatically etc. This way the unit constantly monitors and adjusts the pH level 24/7.

I have seen this setup on the homegrown extreme pro boxes, but Im not spending over $3500 for one of those.

So if anyone knows of places that carrys what I am looking for within a reasonable price please let me know, also looking for a system that monitor ppm and will release co2 automatically as well.
