I recently moved, and the unfortunate side effect was going from well water to city water and realizing halfway through the grow that things weren’t quite right. Turns out I need to ph down and that was beginning to seem like a daily occurrence when cultivating in hydro and trying to hit the magic reported sweet spot of 5.8.
Turns out there are tools to help. I opted for the inexpensive (still expensive) Milwaukee controller. So far so good.
I bought a bottle of distilled water and diluted my ph into it. The pump now doses the system to keep it fairly steady at 5.8. With this system being on a float valve I found that with the water constantly topping off the PH was a moving target.
As a lazy grower, it is money well spent in my opinion.
