We do, but not as often as five years ago, when we extracted most of our oil from bubble, to avoid the chlorophyll and water solubles. As almost all of our oil goes into orals or topicals, we have since developed a non polar solvent extraction that meets our needs without the added step of making bubble hash or dry sieve first.
Bubble extraction is also limited as to how much you can extract, before starting to unduly contaminate the harvest with green plant matter, so we still do a non polar extraction of material that we have already processed for bubble, to glean the residuals.
