"I am making concentrate for use in a low wattage vape pen, using the disposable batteries because the higher wattage batteries burn up the atomizers in small carts so with this being said I will need to decarb right? Probably making my concentrate using grain alcohol wash and was going to let it air purge or cook it off ( haven't decided yet) is there an advantage to either other than the obvious fact that cooking it off gets done quicker. Any advice would be greatly appreciated. This will be my first run with this so any help on some of the best methods that others have already come up with through trial and error would be great. I have done hours and hours of research but there is some conflicting stuff out there. "
