Well I don't know if it's helpful but here is how I do it....i melt some coconut oil down and pour in my weed.....too much and I add more weed, too little and I add more oil. This is seriously how I do it so I know its not any help.

Ps....I think X-Crispi mentioned that 1 full tablespoon of coconut oil equals 14 grams. Maybe that will be info you can actually use. :wtf:
