Thank you for your response. 
3% sounds incredibly high yeild of pure CDT from plant material.
I’ve heard of some buds testing above 3-4% terp content…living soil stuff…but even 1.5% YEILDS seems really high from what I’ve heard. May I ask how you know this to be true?
Are you speaking from experience or hear say?
*I hope Im not coming off rude…I’m genuinely asking. A few I’ve talked to in the past said 1% would be very high. (I’ve never extracted terpenes personally, way above my expertise, I just buy them from others.)
I do know some ppl are very good at it…use different methods than most…just shocked if it’s possible to pull 3% from flowers and them be pure.
May I ask how you came to know that?
