Maybe they should just make Rosin? That and dry sift and water hash are permitted in Calif. You can get very high yields of Rosin from good dry sift or water hash I have seen over 75% and it is legal as far as I know as no solvents are used.
I will wait until the dust clears before jumping to conclusions if they were just testing or a commercial production facility, but either way they do not deserve jail or the shit they are in. I have seen very large co2 and BHO production facilities in Calif, huge... No way they are legal like in Colorado, in fact several were moving to Colorado when I visited.

Yes, Sam, We know about Bubble Hash, in the backwoods USA. I definitely prefer it, and pay special attention to making concentrates of quality without Butane. People seemed to have lost interest in water and Ice extraction for the butane products that do make crappy product yield something worth something, I suppose.
Low-Grade growers blasting whole crops rather than grow good flowers.
