So I have been thinking about the % of terpenes that are infused into distillate to make carts. The majority are adding anywhere from 5% to 15% into their blends when making carts. That I know of there are no studies on the effects of terpene vaping. A recent post about smoking flower compared to concentrates got me thing about concentration levels. I’m going to use easy numbers to keep it simple for this example. If I was to run a 1kg extraction(trim) the yield would would be approximately 100g’s of concentrate. Of the 100g’s depending on strain the yield is 7-14% Terps. Using 10% as my average that gives me 11.70g’s of terpenes which is an average for what is added to a L of disty. At these numbers what it seems is you are smoking the same amount of Terps found in a G of flower/cart, .0117g. Is this correct or am I off here?
Not technically vaping, but, inhalation exposure.
Seems correct to me little on the high side for flower but yes
Yes i can see those numbers for terpenes on a extract bho/pho
But straight dry Flower i find in my reports around 7/8% terp or lower
Guys we’ve done between 60 and 100 terpene extractions they all range in yield between less than 1% and the highest was 3% but usually less than 1.5
My average for the past 65 batches is 8.35%, the highest being 16.94% and the lowest being 1.33%.
Edit: Over the past 275 batches, average is 7.46%, highest being 21.4% and lowest is 1.2%.
These percentages represent percentage of the crude.
Yes @betroit is right about the terpene
Content of dry Flower 0.5/3 %
My 7.2 % is of a freeze dryied sample
And done by a lab that is very modest if accurate at all 
My numbers are similar to @Betroit and @ExTek90, although we occasionally see higher terpene yields and higher % terpenes in crude from nicer input material.
We also have farms, and typically our greenhouse flower (which we think is quite fragrant and terpy) comes back between 3-5% terpene content. Highest I’ve seen on a flower CoA was 8% but I think that it was a fluke lol.
I personally use 2%- I find a better flavor with it not being over powered by limonene.
So if your turbine content comes back between 3-5% is that based on an analysis of the dry flower
And if it is then what percentage are you able to extract off of the biomass
Yes, that 3-5% is terpene content by weight of the dry flower. I’ve mentioned it in previous posts, but if we are using full flower we typically see around a 3% yield by weight as clear gold terpenes. Some strains have put out as high as 4% or 5% but those are few and far between. We typically run a mixture of popcorn buds and high quality trim though, which is typically more of a 1-2% yield.
We usually yield between 75-80% of the terpene content present in the flower when we target them for extraction. It’s tough to get all of the terpene content out without pulling fats/waxes/cannabinoids, as the terpenes that make up that 3-5% dry weight of the flower cover a very large range of boiling points, molecular weights, etc. So we are usually pretty happy with what we get, it is extremely characteristic of the flower material and looks nice.
Flower usually tests around 1-2% terps but one thing to remember is most labs are only testing for 20-30 Terpenes so there are likely other volatiles in there (terpene or non) that aren’t being considered. Highest terp result in flower I’ve ever seen by a long shot was 4.3%. Anything pushing 3% is impressive in my book. I can’t say I had any of the characteristic terpene irritation/nose burn etc associated with high terps. I imagine smoking flower loses a lot of terps to the open atmosphere versus an enclosed cartridge so it might be tough to compare smoking flower to vaping oil.
10% real cannabis derived terps is still harsh in my experience. I don’t know of people doing 15% terps in anything. When I’ve gone over 10% it was extremely runny and way too harsh.
