Ratio of Vaped Bud for Ganja Butter?

[irydyum]

For 4oz use 3-3.5 lbs of butter. Yes it works for vaped buds because I've made it and got really high.:hippy:

Wouldn't it stand to reason that if you are getting more THC out of your vape duff, then you aren't vaping all your weed? My understanding was that the vaporizers big attraction was it's ability to extract almost 100% of THC from herb.

So if you were vaporizing all your bud, then making butter out of the duff, shouldn't all the THC already be gone?

Just some food for thought, I believe that you make it and that it works well, just curious if you weren't getting all the punch out of the vape, that's all.
