To Cover, Or Not To Cover.

cannibutter from growfaq, theoretically would i cover the crock pot or not??

yeah cover it up. i just made some cannabutter with an oz. of ak-47 to a lb. of butter and left it covered for 8 hours on low. its hella dank!!

thanks, now would it be an issue if my crockpot was old as hell, and was only gettin the mix to about 175F on high
