PH AN EC METER, ANYONE TRIED THESE?

I haven't tried those.. are you growing in soil or hydro? I bought a really expensive ph tester. The funny thing is that I really don't need it at all anymore. I am growing in soilless. Once I got to know my water I never needed the meter again.. I'll occasionally use it if I need to really drop my water ph for cloning or something.. That's a decent price though if they are a quality product.
