Correlation Between BHO Yield % And THC/CBN/CBD Content of Strain? - Page 2 - Cannabis Concentrates - International Cannagraphic Magazine Forums

So, what's the verdict? Can you expect to yield roughly 25% bho from a 25% thc strain?

You are looking for extraction efficiency numbers. In other words the amount cannabinoids that were removed in the extraction. A 1000 grams of 10% cannabinoid content material has roughly 100 grams of cannabinoids available to extract. If you extracted 90 of those gram then you had a 90% extraction efficiency.

Where people get confused is getting this confused with extraction yield. Some might think that a 10% extraction yield on 10% cannabinoid content material is great. But if that extraction yield is only 50% cannabinoid by weight then you only have 50% extraction efficiency which is not that impressive.

Homogenized Pre extraction test and Post extraction test are the only way to keep track of the extraction efficiency.

so, how can I quickly asses potential feed material to avoid surprises? I realize the thc content only contributes to total hash yield along with the other compounds.

Grade your material by tested potency and know the yield range you would expect from that grade.

You will have to still take random samples to insure that you have fully extracted to your desired extraction efficiency. However you won't have to test post samples for each extraction so long as it match the yield of the tested sample.

Buddy saves all his spent material from his bho runs..

once run nugs busted thru a screen and ran once ...is saved...

his buddy re-runs his spent material with iso....gains another 5% (turned in to distillate) is his avg not sure what his percentage is on the distillate..

His buddy does it once every 4 months or so when they have enough spent material..

he recovers his iso with a rotovap i believe.

Well, if you're talking about making crude BHO, and you do a thorough job, 1000g of buds containing 25% cannabinoids should produce more than 250g crude BHO. If you're doing it warm, it will likely be 300+g and even at subzero temps, likely at least 260g. Although you may leave 10g of cannabinoids behind in the material, you will likely be pulling out 20+g of waxes/undesirable compounds.

Once properly distilled, you will end up with less than 250g because of that 10g left behind in your material plus some amount lost during your extraction/refining process. The better you get at your technique, the closer you should get to that 250g number.
