Urbanfarmer,
How do you or what do you use to check the Ph and EC with to make sure it is accurate? I have been told that the paper Ph strips are junk and they have too wide of a variance to be reliable. the only other tool I see that is really accurate is pretty expensive ($150.00). What do you use to check the Ec and does that vary form week to week in the water supply or is that a constant reading through out the season. Check once and done or a regular (weekly, monthly?) check? I should have thought to ask this when I had the soil scientist at my disposal a few weeks ago.
