I've been reading a lot about BHO and I'm planning to make a batch soon for use in an Ecig. My question is when do you decarb the weed. I was thinking about doing it before I run the butane thru it but not sure the effects it will have on the oil. I've also seen where it's done in the oil state. Input please as I am now to this and won't want to mess up my weed.
