I read and followed the recommendations on this sight for making vape oil, but it is not coming out well. I followed the advice here and got a great plant with huge buds and powerful smoke, but I prefer to vape as the smoke is more harsh.
I used everclear 151 (75%) and let the ground up and decarbed weed sit in it for two weeks, with liberal shaking. Filtered this through a coffee filter. There was too much alcohol in the mix so I used a double boiler to lower the alcohol and added some glycol and glycerin. What I ended up with was not so much an oil as a tar. Large globules of tary THC form on the bottom and the sides. This tar is too thick to use as it clogs up the syringe and the vape canister.
What did I do wrong?
