Yeah I’m definitely not biting for the calcium or nitrate meters, but I’ve had the pH meter and I like the quality a lot, and I just got the EC meter with the K meter. I’ve already found pH + brix readings to be pretty useful. I realize all of this has its shortcoming, but I guess I’m interested in being able to just measure some parameters and using that info as a tool to sharpen my observation skills and learn more about our system. Next is sap analysis, after we stop growing so many different crops.
