I've notice slabs run with more propane don't smell as terpy; GW also confirmed this in one of my earlier posts. Anyone know why propane heavy slabs are so much stickier and less stable? Originally I thought it was more terps.

Is the reason propane doesn't pick up the C 30 molecules (whatever makes oil darker) because it is so much colder, or does it have to do with the different properties of propane? Thx all.
