Bullshit! No Fucking way in hell does it ADD a 10% yield when extracting bho.
Seriously man? Most average 10-15% return. Those are some outrageous claims Holmes.
Depends on what you're running and the processing. Trim can vary a lot, so for the purposes of bragging rights I suggest we stay with buds in this discussion.
Now lets define buds. The highest BHO yield that I've personally witnessed, was 28.1% and was from bud that had been manicured and the highest I've personally yielded was 21.6% from manicured bud.
Strain makes a big difference, and the lowest I've seen was 5.7% from a Catalyst whole plant extract, a high CBD strain.
That leads us to whole plant extracts. Us'ns and most brothers and sisters remove the fan leaves first, because even though they have trichomes, they are sparse and produce a different quality extract. That leaves us with the buds and sugar leaves, including popcorn, and on average our high THC strains are producing a 20% plus yield, and our high CBD strains producing 18% or so.
Unless we are weighing Absolutes, plant wax pickup adds to the weight, and is typically highest in outdoor grown product, extracted at ambient temperatures. Lowering the temperature reduces wax pickup and requires a longer extraction to yield the target elements.
That leads us to the next step, and that is bragging rights. I extract oil differently for show and tell, than I do for making oral meds, or if we plan to make clear out of the product afterwards using winterization and short path distillation.
When I go for bragging rights, I make two extractions. One for bragging rights, and the second to not waste what I left behind. Certainly I expect at least a 10/15% return on the bragging rights part, with our current strains.
Soooooo, the message is that everyone isn't talking the same language, which introduces a layer of confusion, even before we reach the posturing with BS part of bragging rights.
