Ok, I tried search but no luck. If these Qs have been answered elsewhere please direct me.
1) Best method to test PH?
2) What equipment / supplies do I need? And best place to purchase?
3) How important is PH testing / how much should I focus on PH as a beginner?[/list]
4) Is there a metric/guide as to what I'm testing for?
Thanks gurus!
