Using pressure, you can extract plant material using much less solvent than other methods and get higher yields. Here's a handy manual pressure extractor which is under $20. You put your material in, wrapped in polyester or nylon mesh, sit the unit in a bowl of solvent (preferably subzero butane), let sit as long as desired and squeeze the solvent out. The crushing of trichome heads will expel more resin like a rosin press. Using the Oil Buddy, you can optimize your medicinal herbal extraction operations like never before. Testing showed that "blasting" BHO leaves about 7% THC in the waste material.
Come to think of it, if you used alcohol you could use a spray bottle to spray just enough on the material to completely wet it. That way you use minimum solvent. The solvent would be enough to allow the resin to flow at room temperature, thereby avoiding all heat. It could be called solvent assisted rosin pressing. In fact maybe butane could be sprayed on right from the can.
