To 5°C (41°F) specifically.
Is anyone else bothering to measure and adjust temperature of the ice water before a run?
I haven't done this as of yet in any run, and the other few medical growers I know don't measure the temperature before running their material through. However Iam going to start at least looking at the temperature with a fairly accurate thermometer during the collection of the next batch of hashish.
I'd love to hear of anyone's experience.
