Hi guys and gal's it's my first time making cannabutter. I have a oz of not the best bud and a half ounce of small bud but better quality. Do I have to decarbe the weed first because I've watched a few videos and they didn't decarbe it they just left it in the butter for 3 to 4 hour's. I'm a newbie grower long time smoker. Any help will be much appreciated thanks in advance.
