I just got my ppm meter in the mail today and my tap water reads 147. Am I able to use my tap water for my dwc buckets?
Depending on your location, tap water's content changes which theoretically results in slightly changing how the plants react. Personally, I cant tell a difference in how the plants react between RO and Tap, however the meter reads different between one and the other lol... Just keep an eye on how they respond and you're right as rain.
