Yeah, I had read about that. I really don't see color being an issue at this point though. Organics are of interest to me too so it would in the future. Thanks for the equipment recommendation. That sounds like a great price, too.
lemonboy Reviewed by lemonboy on . pH: Drop testers? Is the GH drop tester an effective way of measuring pH? I realize it isn't near as accurate as a digital system. I just wonder if for the hobbyist... keeping the pH between "yellow and yellow-green" is a worth-while approach. Just looking for opinions. Thanks. Rating: 5
