Hi Brix meter Expereinced, What type of refractometer do you use? Here at the SHC we have a digital stationary one in the lab, where the sap goes into a 5mm diameter dish with the reading bulb(?) underneath. I don't get enough sap out of my plants to get a reading. Would I need much less sap for a handheld refractometer? I thought I ask, before I buy one. Many thanks for advising me. Christiane Jaeger
